Performance Brake Pads - 7 Key Characteristics
HTML-код
- Опубликовано: 18 авг 2015
- When replacing your brake pads, you may choose performance brake pads depending on the design intent of your vehicle. Brake pads very widely in quality, with different temperature ranges, wear characteristics, and frictional coefficients. Which brakes pads are best? Depends on your application. Brake pads used for road cars can be quite different from race cars, requiring more cold bite and less top end performance.

NEW VIDEO EVERY WEDNESDAY! 
Авто/Мото
School of Engineering Explained. My friend said he learned more from your free videos than he did at school. You're one of the people who has inspired me to do something great in the automotive world and that I will. I hope I get to meet you one day.
***** Very kind words, look forward to meeting you alongside your something great!
***** mechanics. For him to become a good mechanic he had to better understand automotive parts which is what he struggled with in school until I showed him this channel.
***** In engineering school you mostly just learn theory. This info is useful of course, and probably more practical than what is learned in college, but college is so heavy on theory to weed out dummies.
TennisGvy had 650ish kids in my freshman year of mech engineering and now there are about 120 including me in my senior year. Crazy how many people switch majors i thought it would be around half.
Andres Lezcano How do you like it? My nephew wants to move out of state to study engineering.
Just to add on to the person that commented earlier I go to school to be an automotive technician and you do an absolute spot on job at explaining everything honestly if we go over something in class and I don't understand it I just sit there hoping you have a video for it
Just found your channel. I'm fixing up my first car and I love learning more about the parts I'm fixing. Great stuff sir.
The best, most concise, and informative video explanation I have seen or heard of for pads thus far !
I've been subscribed for quite a while and have watched nearly all of your videos, It's given me more confidence when i'm selling parts because i'm able to explain to customers using the information you are providing us with. My only complaint is that you seem to be rushing through your videos more recently, i'm not sure if you're just limited on time but your slower videos make it easier to get all the details.
awwww he's come so far in confidence when starting videos
Enjoy your videos, very to the point and easy to follow. The son of an Engineer I instead went into advanced vehicle design, I find your subject matter very interesting. Retired now, good to see young people still interested in what makes the world work.
I like how you always find nice topics and have the time to base them on graphics. They bring much more info than just a number.
I know that your target audience is already very educated but it would be awesome to have one of your videos on the best driving habits so I could reference to my non-engineer-yet-smart friends.
Perfect timing! I changed my rear disks and pads today!
This is one of my favourite car channels.
+K.H. Thank you, very kind!
Woah! Quick answer!
Then again it is 4:47 in the morning.
You're pushing my passion for engineering even further! thanks man! keep it going!
Again man, the images showing up while you describe the parts is also a great improvement! very glad to see positive changes in your videos!
Good work!
great explanation, I like how you explain why you choose one over the other depending on use.
Thank you for your videos. You take them down to science. Very helpful...
Your videos are the best at explaining stuff like this
Great video! very informative, to the point, quick. Excellent!
Awesome explanation, thank you!
Great video like always!
Great video! Definitely calls for a follow-up, e.g compare characteristics of a few high performance pads, and also why getting pads with super high friction coefficient isn't necessarily going to stop the car quicker: it will trip the ABS (if you have one) or lock up the wheels (if you don't) in case of heavy braking. Very high friction pads require tons of aero to get enough grip on the front tires to maximize braking force.
Good information. Seems like brake pads are a mundane, common sense subject, but it's nice to hear it all explained as well as you have done.
Cheers. Love your videos.
great video as always! I love your channel dude!
good video as usual. keep doing yo thang jason!
Once again sensational work mate!! - keep up the great work. Z
Great video, thanks for sharing. A good addition to this video would've been if you talked about the performance of different pad materials.
Another great video. Keep up the great work
Cool video, always very informative
Thanks for the info!
Your videos are awesome
I have been wondering why heel-toe shifting was ever used. You just explained it. Thank you.
such a cool guy, thanks for the info as always!!
Pads should be made out of the material used in a 1970's plastic doll...you know the one that you would always see intact in the smoking debris of a plane crash.
Funny people never talk about changing break fluid. An inexpensive thing to do, it makes great improvement ....no one believes me.
@YMC-DAB420 Where do you buy that at? I need some of that!
After watching EtCG's video on stainless steel brake (err break) lines, I'm thinking about an upgrade! 😅
It's worth doing if it hasn't been changed for awhile. On a new car, changing the fluid won't help unless you're tracking the car and need a higher temp rated fluid.
I learn a lot on this channel
I click like as soon as the video starts. I know it's gonna be good every time
Good Stuff, Great Tips😃👍🏿
maybe a better video would be the comparison between semi-metalic and "organic" ceramic pads, which most of us buys
frank james I agree. I've seen some comparison, but this guy explains well. I would like to hear his opinion and what he thinks about it.
frank james Yeah, I'm still confused with those. What's better in different situations? Ceramic, metalic, organic - there are so many of them.
+frank james semi-metalic is better for track/street use as the compound has a high temp range. The ceramic pads are really good for street use as they have low dust and noise and some can be used for a track. Organic is purely for street use as it has good friction from cold but really bad for speedy driving as they will overheat really quick
I agree
frank james Organic if you drive like a woman. Semi-metalic if you want to stop.
I love your videos, however I was hoping this one would include information about how the different pad compounds effect the amount of noise, dust and rotor wear you will experience. Any follow up on this?
i bought the hawk hps plus and putted dot 4 fluid to go with my slotted disk they violated my rotor after 1 track day but i did not brake fade at least :)
great video like always by the way!!
thanks jason bro
I can watch this guy all day teach
Thanks so much for your videos. Would a lip along the edge of my rotors cause brakes to produce intermittent chirping sound while driving? Thanks for your time and patience.
I'm going to grad school to study stuff like this. Materials Science and Engineering. Love the vids Jason!
So did you join any institute to get study it?
I want the caliper that goes around the whole disc. 20 piston calipers for my Civic.
#WheelLockUp
And then how will the rotors cool down?
Boyd W through the internal vents
@@MustangsTrainsMowers The caliper cools the rotor down, too.
@@MustangsTrainsMowers You will need a extra radiator for water cooled discs.
Btw... I think the original comment was a joke
Your art work is getting slightly better. Lol 👍🏽
Great video. I kniw this has been asked alot before and you answered to this in a Q&A but... What about project integra?
+Engineering Explained, did you bug my car this morning? cos my wifey was just saying she wanted to change the brake pads on her car! You posted this just in time!
Damaged/old brake fluid plays a big part in break fade - a simple flush every year can makes a lot of difference.
But full flushes, most auto shops don't bleed the brakes and only replace what's in the reservoir.
Oblithian Too true..
Oblithian that's a good way to do it. of you use a clear pipe... just fill the reservoir up and bleed every brake. starting furthest away from the reservoir until they become clear.
of you change you fluid every 2 years or 12,000 miles. then why you need a hard chemical which eats the brake lines too?
I had huge Brembo brakes and rotors with ceramic pads and they failed immediately on the track.
I had to pit and have my pit crew put in my Cobalt Friction racing pads. Back on the track and the racing pads are impossible to overheat and fade.
Castrol Srf $80 a pint full synthetic brake fluid is a must!
thank you for the explaination. Quick question, would new cars brake assist systems like the chrysler Ready Alert Braking system increase wear on the brake pads?
You sir are a genius
thanks for the info.....now..Mr. Engineer please design me some Magnetic brake system choices and get them installed on my z4 roadster....thanks
P.s I watch all your vids and I really appreciate the time and work you put into them.
Hello! Which pad material would be better for small track days and city drive at the same time?
Maybe ceramics? What's your opinion?
By the way, thank you for usefull videos!
For your Integra, look up 95 Acura Legend coupe 6spd dual piston calipers. Grab Mini cooper base rotors, and grab the T23 caliper carriers off the 4 cylinder min 90's accords. They will all fit on the integras, massive stoppage for not much. I am waiting to put the dual pots on my new to me prelude.
I've had brake fade once coming down a very tight twisty hillside road while on a "spirited" drive. By the time I got to the bottom I had almost no brakes at all. It's quite unnerving.
theslimeylimey cool thing is the more they heat up the less they brake and reduce heat absorption which works as overheat bypass
theslimeylimey Usually, you will still be able to slow down with the e-brake as the rears will likely heat up less. Had this with my father's car (turned out the car just needed to be serviced and still had factory brake fluid), pedal to the floor had actually less effect than downshifting : I ended up going straight instead of turning at an intersection, put two wheels on the grass and pulled the e-brake to do a u-turn and stop. Tried driving a bit a slow speed to help cooling a bit before stopping, and then tried to pour snow on the brakes. That was a pretty funny moment^^
GT-Alex good tip about the e-brake. My car was a manual so I used the engine as a brake while I stood on the brake pedal which slowed me down enough to make the corner. It felt like there was grease on the discs.
theslimeylimey
Although, I would recommend pulling it slightly only, unless you're very experienced or trained to this. I think the reason is pretty obvious.
+GT-Alex Pouring snow on the brakes isn't a very good idea, could end up cracking/warping the rotor.
Great channel, great content. What are your thoughts on breaking in or bedding new brake pads? Is it necessary to do or just a myth?
My dad makes his own brake pads for our ATVs by JB welding clutch material onto the plate. From personal experience they last longer than OEM brake pads and brake better under wet/dirty conditions.
There are soo many different types of materials pads are made out of, do you have a video explaining the differences of them?
hi
first thanks a lot for what you are trying to do and for what you already have done
second we are trying to make an f1 car to participate in the formula student competition and i am holding the braking system part and now with your help i know a lot aabout braking system but i have problems with calculations of forces and these things and some problems in choosing suitable parts and components
so i hope you can help me with any video that will ease the selection on me
thanks a lot
How does ABS work? in depth like when is it activated and how does it know, how does the ECU calculate slip and relative velocity?
yes i just putt on 4 pair for customers last week .the cheap under $20 pads ar asbestos still to this day as are the low end clutchs
I would like to begin my comment by stating that I love your videos. I would like to suggest that you begin making videos on motorcycles. There is a considerable amount of technology that needs your superb explanation skills. I feel as though it would present an opportunity to gain a good number of subscribers. I understand that your passion seems to be with 4 wheeled vehicle but being an engineer I'm sure it's not too large of a jump. Just a suggestion.
I started watching your videos long time back but now i got to see this video when i am searching material for my masters dissertation this is very helpful :) thanks and can you tell from where i can find more papers and research material for my dissertation in automobile mostly on materials?
What subjects do you have for this dissertation?
Was there a follow on or part 2? Think you left a lot out 1 slot or 2 slots, smi metallic vs organic.
Thanks for the video could you do a video of the hot wheels 332 foot jump truck please ;)
omg thank you. it was time to change pads and there is nothing on youtube to help me decide
can you make a video of blow off valve ''bov'' plz
can you please explain what does the current iVTEC VVTi double vanos ect. works? whats the different from previous generation
I just bought a B4 Sub and it came with slotted and drilled rotors: what pads do you recommend for this application?
All I do is look for akebono made in japan and always had great performance that last!
I have a question. I have akebono euro premium ceramic brakes. Would they be considered racing or just performance?
what type of brakes would you put on something like your Acura or any family sedan like what material
I will like to know how to choose break pad regarding blocking force
Those brakepads you shown, where those Ferodo pads for Girling brakes? I think i recognise them.
If you have a car traveling at 60mph with normal family car brake pads, will it enduce less wear on the brake pads and rotors to stop quickly in a short distance or stop slowly over an extensive distance?
I can't decide for the Subie, Stop tech pads and rotors, or DBA Rotors and Hawk 5.0 pads? or Stock (which I guessing are akebono) ??????
I would have liked to hear you talk a bit about which types of pads (pad materials) give off more or less brake dust. Is there a general trend/rule in cost of braking performance for the low dust type or can you find a low dust pad that still has good braking?
yes. our pads have very few dust. It is ceramic formulation, without any metal.
Wonder how good them Callahan Brake Pads are?
What about towing and 4 wheeling? Some vehicle uses the brakes to act like a limited slip, what would be the best pads for them?
+enggeneering explained sir can u plzzzz help me with ecu of active suspension
i hope that to talk about ceramic pads and a regular one
Thanks, though I wish you spoke more about pros/cons of the various material options.
mwsaplam It's certainly a complicated subject. There are dozens of materials, but often times you're not going to be buy "x" material, you'll be buying some composite of many numerous materials. Hence, it's important to look at the temp charts and see how the pads perform.
+Engineering Explained Yeah, good point. Thanks for the reply.
What material should my pads be made up of if I am making a Gokart?
Engineering Explained I upgraded to larger calipers before and went back because it seemed my brakes would fade much faster and last much longer. Is that because of the components not cooling down quickly enough?
Hi! my 2018 BMW M4 with 25k miles currently got front brake pads at 5mm thickness (NOT carbon ceramic). With the car, brake servicing warranty was purchased that will expire in 15 days. BMW doesn't service unless thickness goes to atleast to 4mm. No chance of getting the car to track/autocross, any other specific driving style may use 1mm thickness with 50-100miles driving? :) Thanks!
what about rotor wear? which one causes less wear on the rotor?
I always thought the changer on the edges was used as another more visible “wear indicator” as in if the pad wears away the chamfered edge the pads are close to being worn out. I know they use a metal strip that drags along the rotor and when that happens the pad is gone and needs to be replaced.
True story but way older vehicle. The pads were worn down enough where the rivers used to connect the pad to the backing plate wore down and was digging in the rotor.
Great video.. I'm in the market to replace my rotors,pads and calipers on my 2000 4Runner.. every 2-3 years my rotors get warped cuz if the heat and I have to have them fixed or replaced. Any brand recommendations for rotors pads and calipers since I'm planing on changing all 3... ??? Thanks
Hugo S. 4Runner are notorious for caliper failure
AJ L crap , I did not know that... any advice on what brand to replace them with?? The OEMs are 500 a piece.. screw that!!!
a lot of big brands like textar and ate,etc dont put frictional coefficients on the box to now how they work
I really appreciate your videos. What is torque(Low, Medium, High) in reference to brake pad characteristics? Keep up the great work!
does suspension effect stopping distance?
Two piece rotor breakdown please.
A comparison between ceramics semi metalics and standard pad material would be good
#question i have seen this on many makes and models of vehicles , why do manufacturers make the pads smaller than the disk , what i mean is radially the pad does not cover the disk leaving a thin line of metal all around the disk , i would like to hear your thought on this since in my opinion its just so you have to change break disks every time you change the pads ( just like what Scotty Kilmer thinks )
No need to change disc. Its not a big deal if brake pads size is small.
I have been fighting with pad wear and performance in my 2006 4-runner sport. The truck has warped rotors from day 1. Now I have put a lift, heavy bumpers which has added 800lbs. I upgraded to EBC yellow pads which lasted 6000 miles. The orange pads went 9000 miles but no warped rotors! Is there a pad that will last longer and not warp my rotors??
Rotors warp from heat and sudden cooling. So if you are braking really hard and make your rotors very hot then hit a puddle it will warp your rotors.
I have a Porsche Cayman S 2006 3.4 naturally aspirated with red calipers that say Porsche on them, Does anyone know what type of pads these originally come with ? I don’t have the vin numbers, guesses maybe semi metallic or ceramics ? Thanks
hi i want to make some changes in brake pad materials for my project which materials are prefer for me
Great video. Would have been even better if you had made it even clearer that brake pads are always a compromise on something. For example if there was a material that had great coefficient of friction at both low and high temps it would wear extremely quickly. Also you could have explained the basic equation of friction, which doesn't involve area, so just increasing pad size doesn't give you more breaking force. Just suggestions, please keep video coming.
Gavin Newman Thanks, I have a lot of videos covering F=uN so I didn't bring it up again. Everything's a compromise. :)
Okay. You didn't need to explain it, just mention it and maybe get some self promotion! Keep up the great work!
Can you make a video on how spoilers work( I know is obvious but there is a lot aerodynamics involved there) and how do they affect to RWD,4WD and Racing FWD. Thanks man!
Alberto Smith Castro ruclips.net/video/DYpxcE7rBw8/видео.html
Oh! that was fast! thank you! I really wanted to see that!
Tip: For daily use avoid the slot brake pads all you can. They are just there to collect debris and scratch your disks. Otherwise clean them very frequently. Live and learn. ;-)
Hi, I recently replaced my pads and I noticed that the new pads didn't have the slot / cut out in the friction material... I haven't noticed a difference in braking but I installed steel braided lines and new discs at the same time. Considering I was trying to improve the brakes with new lines/fluid/etc, do you think I should replace them again with pads with the slot?
+SpeedVitz LDN The features don't necessarily make the pad, the compound does. If it's a quality pad it shouldn't matter too much if there's no slot for heat expansion.
Engineering Explained Thanks for all the great videos and useful reply.
