I always worry, one day a bus will go up the hill. But it will be so bad the person can’t afford to fix it. You are a True miracle worker. You are the man who seems to always make it work!
Breaking down that close to you makes me consider them real lucky people. My kind of luck I would have just pulled on to the interstate! Good job again as always!😁
As a guy who works with air brakes, those that do, not need to understand how clever the air system is. On the drive wheels that is the primary air circuit. There are two tanks, primary for rear drive wheels, secondary for front steer wheels and air bags, etc. Some heavy vehicles will have a 3rd tank for large air consumption accessories. The brake chambers are the equivalent of a brake cylinder on your car. Instead of fluid they use air. On the rear wheels a clever dual chamber is used. One diaphragm works the service or regular brakes, the other one is a spring apply air release chamber, or can as we refer to them, all built together. When air is applied to the brake chamber the spring brake is overcome releasing it. Simultaneously the service brake can then have air applied to it by the foot brake to stop the vehicle. So air is needed (about 90psi minimum) to release the rear spring brake chamber, while at the other end of the chamber allowing the service or regular stopping brake to apply. No air on the parking brake chamber will cause the parking or spring brake to apply Caging is a procedure where a special long bolt is inserted into the back of the brake chamber spring brake end. The tool along with a ratchet is used to manually release the spring brake making it possible to move the vehicle without air applied. They had a Murphy day here in that when the spring brake diaphragm blew out it fouled up the innards (precision term) of the chamber and misaligned the slot in the park brake chamber that the caging bolt or tool engages into a "T" slot to release the park or spring brake so the chamber could not be caged which meant they had to have air to move the bus. Whew there is the longer short story!
You know Scott, my hero's have always been mechanics, the way they think, apply logic, problem solve etc. So nice to see some young guys like yourself carrying on the trade.
Great video and job! I wish there was a shop like this in the Denver metro area that worked on these coaches and did a good job. Nothing like this really exists here unfortunately.
Reminds me of when I lost a water pump 1 mile from home on the 99 Range Rover 4.6 HSE. I drove home about 1,000 feet at a time, turning the engine off when the temp got near the red zone. Worked out fine.
When I saw the condition of the outside of the brake pot and not that it indicates the health of the internals but definitely was showing age and with a broken spring brake pot on one side, the other is suspect as well. And a few minutes later I was nodding my head at two brake pots ready to install .. doing the right thing which will save this owner a huge headache down the road when the other one would have failed. Those lovely wire braided hydraulic line style air lines, those go to crap after some years on roads that have any salt, they can snap like a pretzel without warning. I've done the very same thing with my two main highway tractors, replaced all the spring brake pots and switched over to the rubber style hoses ( of course the fittings were mostly seized anyway on the old hoses.. go figure ). Yup, do it right and do it once pays in the long run !
@@BusGreaseMonkey The main trucks as well as my grain trailers use 30/30, they have pallets of them for example sitting at a truck/trailer supply warehouse type store I tend to get them from ( bendix brand ). That's the problem with some of the not so common parts and imagine the 20/24's tend to fall into that category, both cost and availability. I have had horrible luck some years ago now with a certain other brand that are no doubt some Chinese crap pretending to be quality at another supplier, the main spring broke within 3 years or so and had this happen twice with the same brand.
A nice trick if you have air leaks and you want to block the air stream: cut that airline and put a bolt in the line. It will close the line quite good. I once did an air line repair with a plastic bag wrapped tight around it and adhesive tape to secure it. It hold 600 miles...
Usually when the cage bolt won’t go in it’s because the spring is broken and the broken end of the spring puts a hole in the diaphragm causing the leak. The broken also reduces the parking brake power. It’s a good idea to replace all the spring brake cans after 10 years or so. They do wear out. They are not too expensive if you get them from a truck repair shop and it’s WAY more convenient than being broke down on the road.
Hopefully you use ear protection. I'm 55 and tinnitus is a real thing. Not bad yet but I've shouldn't been so cocky in my youth. Yeah born in -69. A different time. Learn from your predecessors. Hello from Finland!
A memory from over a decade ago. Wasn’t Country Coach based out of a small town in western Oregon on the east side between OSU and UofO? I lived in that area. I also lived in Delaware, Ohio (just north of Columbus) which made Flexble buses and coaches (that one is 30 years ago now.)
That parking brake can release was a pucker moment for sure. Even with all the prep I wouldn't be able to resist flinching from that! Thank goodness they were at least nearby and the coach could still move. Didn't even know that could even be an issue.
If there's ever a "good" place to break down, it's any place near a shop. If there's ever a "good" failure, it's a failure that allows you to "limp" it back to that shop.
If you have shop air ,I use a schader valve to cage the new spring ,the old one I use a quick connect same as the shop air ,sometimes the spring will break and you can have a terrible time with the bolt
I've had my car for 12 years and the only time it broke down I was only a mile from home. A rear wheel bearing collapsed, locking the wheel. If I reversed a short way I could then go forward for a while before it locked again. I staggered my way home that way and didn't need a towtruck.
Definitely time for some HighRes. outer wear. Your assistant's shop clothes blended into the shadows and road color making him all but invisible. Narragansett Bay
Better to breakdown with that close to your workshop rather than in the next state and pay a wrecker fee on top of a garage that has him over a barrel..
I worked for a company that manufactured spring brakes. All were made with a universal length rod unless they were going to an OE who specified rod length. Rod standardization significantly reduces inventory.
I'm thinking...that if you need to ask how much the yearly maintenance on a vehicle like that is...then they are definitely out of your price range, eh? smiles.
What's the old joke They ask a doctor what he does if someone dies when leaving his office..he replies, "I turn the patient around so they look like they were on the way in." Turn it around. Oh no, it broke on the way in and almost made it...

A CAT???? there's a Cat in Scott's shop...I'm contacting the local media....cats and dogs sleeping together....this is biblical....LOL
Yup looks like the bus grease monkey has a fetish for cat power the he kept in the closet all these years lol It’s Armageddon I tell ya.
We don’t really work on cats. We just do light maintenance.
@@BusGreaseMonkey I know just goofin around
@@sirmister4411i was just pointing that out before another stray cat shows up at my doorstep wanting some major attention ;)
Too late now. The mold has been broken of Detroits only.
Great bus control while backing!
Way better job than i would have done backing up
It was great if backing up directly into the gate and turn on the grass there..
Gotta love the 9th generation F150 headlights.
I love picking out which vehicles RV manufacturers (often) borrow headlights and tail lights from.
That bus must haul on the highway. It ripped up the hill like it was nothing!
That newfangled 4-stroke diesel technology has something to it.

It's always fun being able to identify what headlights and or taillight they used for these coaches. 1992-96 ford f150 headlights.
The coach liked its pampering so much that it wanted to stay longer and get more. :)
If you have to brake down, I can't think of a better place for it to happen. Great fix as always.
You know Scott, my hero's have always been mechanics, the way they think, apply logic, problem solve etc. So nice to see some young guys like yourself carrying on the trade.
At least he broke down when he was less than a mile from the shop.
That's akin to breaking down in your driveway. He was very lucky.
Beautiful Tennessee mountain roads. So calming.
Great video and job! I wish there was a shop like this in the Denver metro area that worked on these coaches and did a good job. Nothing like this really exists here unfortunately.
that break down is the epitome of something unfortunate happening at the right place, like having a heart at the entrance to hospital

We tried to get the tags too but they were 20/24’s and after trying several sources we were looking several days out. No one carries them

Sounds like a lucky breakdown for this guy. Nice fix.
Excellent job
Great place to break down. A hundred miles down the road would have really sucked.
Gosh he was lucky it did not happen out on the freeway bro. Safe travels. Ken.
Nice work with some challenges👍

92-96 Ford F-series headlights and signals. Cool.
"you don't use a strap wrench or anything... We tried that" 😅
Those air leaks are easy to find number to replace the piggy back chamber.
Good morning 🎉
If you have shop air ,I use a schader valve to cage the new spring ,the old one I use a quick connect same as the shop air ,sometimes the spring will break and you can have a terrible time with the bolt

Nice, well, he was luck that that happened by you guys.
Have you guys ever considered developing and producing your own tools specifically for this type of repair?
It's sad that Country Coach went under, while lesser brands survived by making RVs that look as good but are built with sticks-n-staples.
15/16 Ratchet wrench 👍🇨🇦🔧

Those aeronose ford headlights ik them well
Murphy sure had his way that day, eh? Oof. Everything that could have gone wrong seems like it did on that brake can, eh?
That looks like a c12 or a c13 cat
Better to breakdown with that close to your workshop rather than in the next state and pay a wrecker fee on top of a garage that has him over a barrel..
I would have replaced both spring chambers as a pair. If they are original, the other one is probably brittle too.
We did replace both
How do you figure out the length of the push rod in the brake chamber to match the old one, just measure the old one and cut it the same?
Yes tape measure
I worked for a company that manufactured spring brakes. All were made with a universal length rod unless they were going to an OE who specified rod length. Rod standardization significantly reduces inventory.
How long is this bus? Seems awfully long going into the shop.
43’
@@BusGreaseMonkey wow,looked longer than that to me. Nice bus.😘
What Cat engine was in that coach, anyone catch that or recognize it?
C 12. 455 or 500 hp
Well corrosion ate them cans up.they simply timed out
Why do they call it a "cage" bolt?
Well it was close to the shop.....
Weird lookin Detroit didn’t know they made yellow ones
You couldn't release the maxibrakes ?,nvm you answered my question in the video,
They would release until the air bled off quickly as soon as you released them
Next time you face this problem .cage the pot and take a pair of welders wisegripes and pinched the line
Watch the video to the end and we explain why
Why is he driving on the wrong side of the road?
I'm thinking...that if you need to ask how much the yearly maintenance on a vehicle like that is...then they are definitely out of your price range, eh? smiles.
wish you had blocks under the axles instead of just jacks.
The body is on jack stands.
You can take vice grips and clamp off the hoes going to the brake chamber and stop the leak until you get it in the shop
Brake wouldn’t cage and the air lines were not rubber hoses
Couldn't cage brake pot??
The spring was off center and the bolt would not go into the slot
Please turn the Volume Up on your Videos. We (I) can barely hear you the last Few months now. Is it just me? Or my IPhone 8 with a bad speaker? 🤷♂️
It’s you, volume is fine for me. 🤷♂️
it's you
Buy a Bluetooth speaker....I use one with my phone when watching RUclips videos and it amplifies the sound quite nicely.
Headphones 🎧
It’s on your end.
Sound is fine here.
Did you let him use the new Transtar for a loaner until Monday? Haha
I always just take a saw off and cut the rod that way I don’t have to worry about pressure
If you're going to break down...
Where did the caging bolt go???
😊😊😊
What's the old joke
