How to Replace a Brake Can aka Brake Chamber.

- A relatively smooth brake chamber replacement. My goal this month was to make all of my videos around 3 minutes long. This job came out of nowhere and unfortunately 3 minutes just wasn’t long enough. Hopefully you can all forgive me this one time.
I had a load stick in a rolloff tank while dumping at the landfill. I pulled forward, then I backed up and hit the brakes. The load came out, but when I went to leave I noticed that I only had 60PSI on my gauges. I could hear air rushing through the parking brake valve(yellow button) and the warning light and buzzer came on.
I was able to drive off of the garbage hill to where the city has a recycled-asphalt parking lot for their trucks and got out and could hear the chamber leaking.
I was able to get the brake released and shored up the air leak so I could make it safely back to the shop.
The parking brake spring had broken and punctured the diaphragm inside the chamber so it needed to be replaced. Make sure to buy the correct part for your vehicle. Thanks for your time.
Heres the link to my extended in-depth video on a more difficult chamber as well as links to 2 other non-affiliated sources on brake chambers.

They way my brother use to do it was separate the two halves while standing in front of it. He only did one though. God rest his soul.
Hahaha. They don’t even put the removable band on the parking brake side anymore. I have just done the pancake on the service side before when I was in a hurry. The service brake spring might break a finger but it’s not a widow maker.
Not laughing at the loss of your brother if that’s a true story. Btw…
@@MikesMischief nope. Just joking.
Hahahahaha I knew you were joking, even though it has happened
Not gonna lie that was really creative for not having a caging socket. We buy sealed non adjustable clamps on the chambers cause people tend to kill themselves messing with the clamps.
Yeah I don’t think they make cans with removable clamps on the big spring anymore. I haven’t seen one for quite a few years. I mumble a bit but yeah I just use the truck air to pull the spring back if there’s enough left of the pancake.
the best part of the video was the end , nothing brings more joy to a parent than kids having fun , those memories last forever , you are blessed !
Thank you Frank.
Thanks for sharing! Great job on the brake can change!
Excellent video, showing everything, especially being on the ground where it’s most likely going to happen 😊
Thank you!
Excellent video on the description and work explanation.
Awesome video my brother! 👍👍👊👊🔥🔥
Thank you 615!
@@MikesMischief your welcome
I don't know what some people are talking about, you said it clearly in the video that you have different brake chambers. Some people just like to talk😂😂😂😂😂😂 Thank you for you very informative video
I know it’s illegal to have different cans on the same axle. That being said if you only have one or the other you can get by for a couple days while you’re waiting for parts to come in. The difference in throw isn’t actually a problem until the shoes are worn down. The short throw cans are $30 at Napa and for some reason a guy always has some lying around. I ran it for a couple of days until I got a long stoke can in and had time to put it on. I wouldn’t do that if you live in an area where you cross an active dot scale daily but that’s not the case here. Stupid? Probably… but it is what it is and I’m ok showing it in a video because that’s real life and a guy might have to do it to get by sometimes.
@@MikesMischief Thank you so much for the information. I really learnt a lot from your video
Mixing brake chambers will get you put out of service by DOT.
Plus a huge fine. 😢
I understand what you're saying though.
👍👍👍
Brake can work replace them s cams and bushings oh and do some wheel seals
Bushings are like the herbal supplements of the braking system.
Maybe I’ve been doing it wrong but I just back off the slack adjusters and then let all the air out and done deal.
If you can back your slack adjuster off with the brakes set then your brakes aren’t working properly. These should take 45 min tops and there’s no reason to let all of the air out of the truck.
You text edit about long and short stroke chambers being a DOT Violation is inaccurate. The stipulation is the same "size" chambers. Size is defined as the diameter of the chamber, not long stroke vs short. Just an FYI.
FMCSA/DOT Section 393.47 Subpart b says “The service brake chambers and spring brake chambers on each end of an axle must be the same size.” I copied and pasted that from the FMCSA website 2 seconds ago. I didn’t see “same size” defined anywhere. Do you have a citation where they define “same size”? Long stroke cans are visibly larger not the “same size”.
Good instructions though. 😂
buddy you have wrong new brake chamber. the old one is long stroke , the new one is standard stroke...
Yeah I caught that in the video. We just ordered 4 new long stroke cans and replaced them all.
Dude! That's an out of service violation!
You can't mix brake chambers. I understand if you have an emergency. However,
In a regular replacement situation, that will get you in a lot of trouble with the DOT!
I actually said that in the video.
@4:56 that is not the correct way to measure to cut the rod. there could be issues inside the can that cod cause that measurement to be wrong. you are suppose to mount the chamber then use a square to mark the rod off of the center of the S-cam.
I’ve been working in shops for decades and I’ve never seen someone mount a can just to get the measurement. I’ve used a long square when a can blew out and there was nothing to measure. You can measure from the center of the s-cam to the face of the bracket with a long square because the bracket itself is a square surface that is normally flush with the face of the can when mounted. Square is square so it doesn’t matter if you measure the top, middle or bottom as long as you’re measuring from the same square surface. When the spring is shmucked inside I use a metal coat hanger or wire to get the measurement if it’s not too far gone. The average person is too lazy to mount and then unmount a can for a measurement. Probably the “correct” way but certainly far from the most common.
@@MikesMischief i dont unmount mine. I cut it off while its still on the bracket.
@@TORAH-613 this is the right way to do it. anyone that matches rod lengths is just following the prior mechanics footsteps. sometimes, even the engineers footsteps... it can be done but i think its payrate subjective
New brakes new drums. Brakes won’t stop heating up. Tried adjusting the brakes but slacks automatically adjusts itself. If anyone can help.
Did you get the right shoes? I’ve seen guys put the wrong shoes on and they drag and then heat up.
@@MikesMischief I have no idea. I just took it too the shop and had them replace everything. Two brake are working perfectly fine. Its just the the other two. That wont stop. I just noticed one has already started polishing the inside of the drum.
@JagdeepSingh-wv1ry I replaced the brakes on a trailer once and the drums went on tough. I told my boss and he said run it. I took a infrared thermometer with me and the drums maxed out the thermometer (over 500°) in 3 miles. We ended up taking them off immediately. They sold us Q-pluses instead of Qs. The other problem could be the air lines on the wrong hole in the can. Did they change out the can? Is it on the truck or trailer? Are your glad hands hooked up properly?
@@MikesMischief its on the truck. I have a 2003 fLD freightliner. Now I did little research the one that they installed have 3 rivet holes. So I’m guessing they are called 4707. Not sure about the diff between 4515 and 4707 are they interchangeable?
@@MikesMischief and mine doesn’t go that hot in that less miles. I have driven over 1000 miles on this. With applying the brakes they get around 400 to 500. I too measured with infrared thermometer. But even without applying brakes I used engine brakes and spike after noticing the drums overheating two of them do go over 200 plus. And that’s with no brakes applied at all.
I'm more concerned you putting the wrong brake chamber back on the truck
Why?
