Damn, that sucks! Great reminder that things can and WILL go wrong on the trail. I lost a master cylinder twice, on an Explorer and a Civic. No fun! Thankfully, both times I was able to use the gears and parking brake to safely come to a stop. These days I won't use any type of traction aid that relies on the braking system. I've never hit any of the MTS, Crawl Control, or any other off road mode button, in my Tacoma. I'm just too paranoid of stressing the brake system. I have 5.29 gears and front and rear lockers. I like old school mechanical traction aids. Anyway, another good video! Stuff like this happening just makes for even better conversation over the end of the day beers!
Well said! I feel that a lot of these comments are in denial that this can happen, and here you are telling us this happen to you twice. Prior to this incident, I didn’t even know this was a possibility. I completely understand your hesitation to use brake based traction aids, hehe.
@@JonDZ_Adventuring forgot to add, you've totally convinced me to get a microwave lol! I started using an induction burner about 6 months ago. I've always dragged along a Jackery 1500 to power it. That's getting old. I'm in the process of adding a second lithium battery to my 12v system, in the bed. Picked up a 2000w inverter to power it. Might as well get a microwave, too! Can't wait to have hot pockets and popcorn in the middle of nowhere! 🤣
I think when the rear one failed the fronts worked until the master cylinder ran out of fluid. The master cylinder is designed so if the front brakes fail the rears work or if rears fail fronts work. The guy should have pulled over immediately after the warning to check instead of driving until all the fluid leaked and caused zero brake pressure in front and rear calipers
@@JonDZ_Adventuring he lost brakes when he ran out of fluid from the leak I believe. If he had pinched it and refilled or stopped it from leaking he would have pressure to stop on the 3 others.
First of all federal vehicle, safety standards require that an emergency brake be a separate mechanical system. Now in modern cars can be electronically operated, but it has to be a separate mechanical system. Therefore, even if your caliper fails, it should still work. Most new large vehicles have an inner drum to the emergency brake actuator on rather than the rotor and caliper. And all my years in motorsports in all my years working as an engineer in the automotive industry, I have never seen a caliper explode. I’ve seen calipers that have been ground down, clear, smaller wheels, and racing applications, not fail. But the key here is to use engine braking so if you have a manual transmission gear down if you have an automatic transmission, lock it in your lowest gear and if you have a low range transfer case use four low, but the emergency brake should always work. I’d love to see a follow up video on this to see what the dealer had to say. I mean I’ve seen rally cars come in with no brake rotor or brake pads left, the calipers still intact, usually damaged, but they still had brakes on the other three wheels and even if you lose a brake line on one wheel, your other axle will still have brakes. That’s why they have dual circuit master cylinders in modern cars loose rear brakes front still work they’re not as effective but they’ll still function. Now with cars with multi circuit modern day, computer controlled ABS systems. It may be cross controlled braking, but you should still have braking on at least two wheels. I heard somebody say something about his dash lit up well that’s the computer’s way of saying you have a critical air. You need to stop now and address it but that also should throw the car into a limp on mode or safety mode, because the cars computer knows if you’re pushing on the brakes, it knows if the car is breaking or not, and which wheels are breaking and not breaking.
Thanks for the detailed information @introverted_overlander ! With all you said, I would definitely like to know your thoughts one why the e brake either failed or was inadequate at helping slow the vehicle down. You can see the Lexus roll down even with the hand brake engaged.
Things happen but sometimes doing maintenance can prevent unexpected issues. Always change brake fluid when doing brake pads or if fluid starts getting dark
That’s a good point too, and a point I wanted to make, but Daklak had his mechanic inspect his rig before this trip and he said the brakes were good. I probably should have mentioned that.
Glad that the auto parts store wasn't too far from where you guys were. Cause of this vid, I'll make sure I have a fresh set of rotors and pads on the vehicle before hitting the trails. Also have a few replacement set 😊, brake is something that can easily be overlooked.
This is scary! My e-brake was maladjusted on our trip to Colorado too. I adjusted them as soon as I got back home. The problem with e-brakes is that they only lock 2 wheels. On a steep grade it may not be enough to stop the vehicles momentum.
Something similar happened to me, but the brakes didnt go out, I was sliding down on black ice about 50 yards and braced myself for impact. It was a scary moment. This was with a 2001 Lexus RX300. Glad you guys were able to fix it and everyone was ok. Awesome video as always 🙌😎
Whew! Scary stuff! That happened to me on “glare ice” (pretty much same as black ice). I went for a ride and steered towards a ditch to slow myself down. This situation is a little different though in that there’s really no end to it unless an impact occurs 😱
Man!! Honestly if complete brakes failed then it would be a situation like a bear attack and what you would do in a life threatening situation! Just another situation to always keep in your mind in an emergency like getting in an accident and going under water
Yeah, I’d say so too. With his regearing, he’s at 40:1, he does have 35” tires though, which are 4” taller than stock. Which brings him back down to 35.8:1 which is really close to the stock 33.6:1. A 10 mph freefall with engine braking sounds about right.
Sucks when things go wrong but you learn how to handle new situations and become more prepared for future issues. That and it always makes for a fantastic memory. It always amazes me that as complex as these vehicles are that they do not break down more often considering the abuse you put them through =)
Yeah, there’s a couple things that played out in this video that humbled us. Failed brakes and random falling tree. Two things that can hurt or kill us, but didn’t, and we learned 😃
Woah! Glad you are all safe and good to see you all adventuring hard and helping each other out. I wonder if the slots in those power stop rotors enabled some kind of rock to get jammed in there which led to the eventual failure. If brake loss happens If you are Low range you definitely can pop it into L1 which will definitely limit your speed and then kick the e-brake. Winches are not rated for dynamic loading (being used while moving) so better to use a strap than than the winch itself for this.
Put it in low gear. Hopefully, he has a manual emergency brake and not those stupid electronic parking brakes... The manual brakes work on cables independent of the hydraulic system. As for dash lights, you might want to invest in a decent OBD2 reader. Just one to read codes, not the type you leave on, and it streams real-time data to an app on your phone. It's great that you all go together and help each other out when things go wrong.
I’d be willing to bet it won’t be very long before you see somebody on horseback or a motorcycle coming up looking for those cows and rounding them back up again. I’ve also heard that modern-day ranchers are tagging their herds with GPS.
Camping Randy called the sheriff and reported the escaped cows. The ranch people went to go retrieve them 😃. Edit: although we did see some walking down the roads ….
manual e-brake is nice, but so is a transfer case so you don't have to depend on it.....They also should be using the strap not the winch, that's just going to wreck the winch.
The Low Range in your rubicon gladiator on 35s is a bit different than a regeared Lexus GX on 35s. 77:1 vs. 41:1. That’s pre tire too! rubicon comes with 33s where the GX has 31s stock.
I was in Vermont off-roading a few weeks ago in my 4Runner, with stock size tires my crawl ratio is around 33 to 1, even in low range first gear I still needed to use the brakes a lot on the steeper descents.
@22:23 wow I am impressed that broken brake costs only 3 hours! I would have never thought to map out where the auto parts stores are and when they are open. Do you think the age of that lexus had anything to do with the failure? Is that a 2008 MY?
I got to ask was he on 4lo coming dow the hill?. 4lo is not only to go up. It is also very helpful to go down on step hills so you dont over work your brakes or if something happens you can brake with the engine/gear and ultimately handbrake
I'm not totally sure, but with the steepness of the trail and my friend recounting his story and mentioning he was descending at 10mph, sounds like he was in 4Lo
e-brake, downshift in 4-lo, kill the engine in gear if i have to, crash if i have to, maybe even roll if i have to. I keep my offroad rigs simple and use OEM (in my case Toyota) parts as much as possible. rear drums and brake cables ftw.
Since your last video covered 4L going up hill, should also mention it also helps with down hill descent, less brake pedal effort. With that said, was the GX was in 4L and 1st gear when the brakes failed? It would make the situation worse without or better with.
In the intro I mentioned engine braking and using the environment (purposely crashing into a tree) to slow a vehicle going downhill. The ascent was steep and the descent was steep, so while I’m not certain, I’m 99% sure he was in 4Lo.
Have faced something similar before;- Was escorting one of our company's lorries loaded with oil palm and one of them lost its brakes. My solution that day was to link it with straps to my Toyota Hilux LN106. Every time it need to brake while going down hill I would use 1st gear 4L and feathered the brakes while that lorry shifted down to the lowest gear it can go to and used engine braking. We did that for about 20km over ungraveled trails until we reached pave roads where it was mostly level all the way to the mill.
Great video and I am glad everyone was safe at the end. I am an ASE master tech and keep wondering a few things. At first I understand the master cylinder fail, and got interested in the video, but later understood he mean the LR caliper cylinder, which correlates a bit why also the E!brake fail once rotor broke. Yet aa far as I know all vehivles required 2 systems master brake cylinders, so when this happens you still have 2 wheels, sometimes they cross left rear and right front. Or front/rear which is less common. Anyhow I have a GX470 and wonder myself what really happened. Being in low gear could contribute to the feeling of no brakes because of the torque even at idle. Or air in part of the orher half of the system. Be safe. I need to adjust my E brake. 😊. Also a good reminder, red light on the dash means Danger, orange is a warning. But typically when you see a red light you should assest the failure right away.
Thanks Rollyman! It’s a good thing that the brake failure happened just 500 feet away from the trail exit, and a town with an auto parts store wasn’t too far away AND… they had parts for a JT120/JT150 platform. That’s the advantage with toyota, parts are available around the world.
Gx460 rear brakes require ignition on/ something about the abs mechanism pumping the fluid. I wonder if it’s possible to shut off engine when brakes are lost to prevent losing rear fluid.
Haha, I learned this the hard way on my 4Runner. I was mid break job and had to turn on the key, and fluid pressure shot the piston out of one of the rear calipers. You lose that piston, you lose a colossal amount of fluid very quickly. Once you know how it works though, makes them easy to bleed.
8:11 I’d open my 270 awning like a sailboat and if that still didn’t work I’d open the hood and doors. 😀 But tbh If I had no other means I’m going into the side of the mountain. Beats going off the mountain
Dude, those cows that kept photo bombing you were hilarious lol Ive had total brake failure 2x happen to me. Once in my old SR5, a brake line, and the Ebrake failed resulting in a rollover crach totally the truck. The other time was in an old subaru, and a caliper piston seal let go. I change brake calipers, and flexible hoses every 100k miles.
Oh wow! You've experienced a lot, that's for sure! 100K Brake service sounds like a good idea. I'm actually thinking about a brake upgrade now that I've added more and more weight to the rig. I've only added what I think are necessary lbs, but the rig is starting to feel heavy. Last time I weighed it was 5400 lbs, without me in it. The suspension is beefed up, but not the brakes.
They start to get heavy. My OBW clocked in around 5600lbs with me in it. Fortunately, my brakes are still more than adequate. I need rear suspension upgrades 100% though. It's not as planted as it was. Dampening is terrible in the rear. It has way too much rebound and it'll bounce sometimes kicking the ass out.
That's a lot of SUV to stop! Curb weight is about 5k stock so add bumpers and camping gear it must be 6,000+ pounds. Surprised the E brake didn't work since I believe it's all mechanical, handle goes to cables and back to drum brakes. Of course if the drum gets saturated with brake fluid your down to just one side trying to stop 3 tons. Glad it all worked out!
Great Video Jon. Such an important topic. Pilots always know throughout their flight....where can I land if my engine dies....they are always thinking about this and aware of the closest airport to them or open fields, farm land, golf course, etc.... This video reminds me to always know....where will I bail out if my brakes fail on a downhill. There is always a startle factor with this kind of failure....several seconds of "I can't believe this is happening" or "what the heck broke" which is extremely critical time during which your speed will quickly build up possibly limiting your options or the severity of implementing those options re: damage to vehicle or injuries. The longer one waits to make their decision on how to slow/stop the vehicle the worse the outcome. We should all have a plan when going down a steep hill and analyzing the options for an emergency knowing at all times, if there is a braking failure, will I immediately turn left, right or continue straight for a better opportunity slightly ahead. As you mention in the video, know your rig and what you can do immediately to slow things down with an emergency brake or a transmission that can be down shifted or put into 4LO (I have to stop to get into 4LO so that's no help) or decide at the start of the downhill to do it in 4LO just in case. If we are not paying attention to the surroundings for a bail out option and/or have not rehearsed in our mind what we can immediately do to our vehicle to slow it down quickly to help maintain control and/or stop it, we are destined for a much worse result. I had an "almost" incident while out riding with a group in some VERY hilly areas. I was not familiar with the trail, we came into an area of deep sand with some whoops and I had not experienced deep sand handling with my vehicle before. Things felt mushy/spongy, steering, braking and accelerating as we all plowed through it. I assumed it was just the sand causing these "handling" conditions. The leader announced on the radio a long sketchy rocky hill climb loop ahead and a flat area on the left to park if you wanted to sit out the hill climb loop. I love hill climbs but I pulled into the flat area where another Jeep was parked to sit it out. I crawled under my rig and my left rear brake line was leaking fluid. Had I gone up that hill climb without checking under my rig first, it would have been a very expensive and terrifying ride down the other side. It turned out on one of the Whoops coming into the sand, my oversized (for the space) spare tire mounted under the back end made heavy contact with the ground/sand and damaged the hard brake line running across the rear axle causing the leak. We were able to do a trail fix with two vise grips, zip locks and duct tape plus a spare can of brake fluid. I was able to complete the ride, with some significant downhills but I did those downhills in 4LO and with awareness as to my braking limitations.
Well said Tim! That experience you shared is eye opening, it's such a random issue. On a trip we did to the Utah BDR, we had someone damage his brake lines running into some foliage. We were able to use vice grips to stop the leak, and our friend was able to drive into town to get his brake lines replaced. The following day he had his power steering randomly fail. That was a reminder that it's not a matter of if something will will break, it's a matter of when. Like you said, we should be prepared for these situations. I like how you said, "If we are not paying attention to the surroundings for a bail out option and/or have not rehearsed in our mind what we can immediately do to our vehicle to slow it down quickly to help maintain control and/or stop it, we are destined for a much worse result."

Had that happen to a jeep Cherokee back with i was nineteen. The jeep had 4.5 inch of lift with 35in tires. Had no sways with the fender Wells cut out for more room to flex flex. Was in just in normal drive and in a steep down hill. Just had to steer my way though. And go with it.
Damn, that sucks! Great reminder that things can and WILL go wrong on the trail. I lost a master cylinder twice, on an Explorer and a Civic. No fun! Thankfully, both times I was able to use the gears and parking brake to safely come to a stop. These days I won't use any type of traction aid that relies on the braking system. I've never hit any of the MTS, Crawl Control, or any other off road mode button, in my Tacoma. I'm just too paranoid of stressing the brake system. I have 5.29 gears and front and rear lockers. I like old school mechanical traction aids. Anyway, another good video! Stuff like this happening just makes for even better conversation over the end of the day beers!

Dude, those cows that kept photo bombing you were hilarious lol
Ive had total brake failure 2x happen to me. Once in my old SR5, a brake line, and the Ebrake failed resulting in a rollover crach totally the truck.
The other time was in an old subaru, and a caliper piston seal let go.
I change brake calipers, and flexible hoses every 100k miles.
Oh wow! You've experienced a lot, that's for sure! 100K Brake service sounds like a good idea. I'm actually thinking about a brake upgrade now that I've added more and more weight to the rig. I've only added what I think are necessary lbs, but the rig is starting to feel heavy. Last time I weighed it was 5400 lbs, without me in it. The suspension is beefed up, but not the brakes.
They start to get heavy. My OBW clocked in around 5600lbs with me in it. Fortunately, my brakes are still more than adequate. I need rear suspension upgrades 100% though. It's not as planted as it was. Dampening is terrible in the rear. It has way too much rebound and it'll bounce sometimes kicking the ass out.
That's a lot of SUV to stop! Curb weight is about 5k stock so add bumpers and camping gear it must be 6,000+ pounds. Surprised the E brake didn't work since I believe it's all mechanical, handle goes to cables and back to drum brakes. Of course if the drum gets saturated with brake fluid your down to just one side trying to stop 3 tons.
Glad it all worked out!
Good point about the brake fluid. And really, parking brakes barely work on the best of days anyway.
Good point! Also.... That thing is waaaaaaay over 1000 lbs. added weight :P My guess is a good 2500 hahahahaha!
We could roll with theses, Guys all the best from mid-West Arkansas.
Down shift to 1st gear in my vehicle. Even with an automatic transmission Jeep Wranglers and Gladiators have an 8 speed clutchless transmission.
Great Video Jon. Such an important topic. Pilots always know throughout their flight....where can I land if my engine dies....they are always thinking about this and aware of the closest airport to them or open fields, farm land, golf course, etc.... This video reminds me to always know....where will I bail out if my brakes fail on a downhill. There is always a startle factor with this kind of failure....several seconds of "I can't believe this is happening" or "what the heck broke" which is extremely critical time during which your speed will quickly build up possibly limiting your options or the severity of implementing those options re: damage to vehicle or injuries. The longer one waits to make their decision on how to slow/stop the vehicle the worse the outcome. We should all have a plan when going down a steep hill and analyzing the options for an emergency knowing at all times, if there is a braking failure, will I immediately turn left, right or continue straight for a better opportunity slightly ahead. As you mention in the video, know your rig and what you can do immediately to slow things down with an emergency brake or a transmission that can be down shifted or put into 4LO (I have to stop to get into 4LO so that's no help) or decide at the start of the downhill to do it in 4LO just in case. If we are not paying attention to the surroundings for a bail out option and/or have not rehearsed in our mind what we can immediately do to our vehicle to slow it down quickly to help maintain control and/or stop it, we are destined for a much worse result.
I had an "almost" incident while out riding with a group in some VERY hilly areas. I was not familiar with the trail, we came into an area of deep sand with some whoops and I had not experienced deep sand handling with my vehicle before. Things felt mushy/spongy, steering, braking and accelerating as we all plowed through it. I assumed it was just the sand causing these "handling" conditions. The leader announced on the radio a long sketchy rocky hill climb loop ahead and a flat area on the left to park if you wanted to sit out the hill climb loop. I love hill climbs but I pulled into the flat area where another Jeep was parked to sit it out. I crawled under my rig and my left rear brake line was leaking fluid. Had I gone up that hill climb without checking under my rig first, it would have been a very expensive and terrifying ride down the other side. It turned out on one of the Whoops coming into the sand, my oversized (for the space) spare tire mounted under the back end made heavy contact with the ground/sand and damaged the hard brake line running across the rear axle causing the leak. We were able to do a trail fix with two vise grips, zip locks and duct tape plus a spare can of brake fluid. I was able to complete the ride, with some significant downhills but I did those downhills in 4LO and with awareness as to my braking limitations.
Well said Tim! That experience you shared is eye opening, it's such a random issue. On a trip we did to the Utah BDR, we had someone damage his brake lines running into some foliage. We were able to use vice grips to stop the leak, and our friend was able to drive into town to get his brake lines replaced. The following day he had his power steering randomly fail. That was a reminder that it's not a matter of if something will will break, it's a matter of when. Like you said, we should be prepared for these situations. I like how you said, "If we are not paying attention to the surroundings for a bail out option and/or have not rehearsed in our mind what we can immediately do to our vehicle to slow it down quickly to help maintain control and/or stop it, we are destined for a much worse result."
That Jeep was all driver.. 😂😂
Did they yank him out with a tow strap? I didn't see much stretch in the rope.
It was a rope, but not sure if it was kinetic. It was a violent recovery for sure.
Had two master cylinders go out o my taco. same part number Toyota refunded me
WOW what a GENEROUS friend offering a WHOPPING 5% discount, truly amazing deal! Doesn’t even cover sales tax! Thx Ian fir the blockbuster deal lol fkn joke 😂
If tell me you don't own a business without telling me you don't own a business was a person 👆
Haha! Ian is a good dude, but he's just running the business with his Wife. While the front skid plate is $275, a set of full armor will be around $1000 and 5% is 50 bucks saved.
Had that happen to a jeep Cherokee back with i was nineteen. The jeep had 4.5 inch of lift with 35in tires. Had no sways with the fender Wells cut out for more room to flex flex. Was in just in normal drive and in a steep down hill. Just had to steer my way though. And go with it.
