I am at a truck shop and they stated they need to locate parts for our coach. Where does one shop for rotors, pads and so on. What are the part numbers?

Those numbers are for front not rear.

You need to double check as I think you need these depending on how hot the calipers and rotors got:
Rotors 3218K167
Pads Kit 15625 PM
Slide pins Kit 15016 or alternate # 15013
Caliper Major repair kit Kit 15007 Left side
Kit 15006 Right side
Helper springs Kit 15018

Depending on how hot the calipers got you may need this # also
Slide pin bushings Kit # 15010

Thanks guys for the help. A couple of week ago when at Goshen, Indiana parked at the fairgrounds we heard a loud clanking sound when we released the parking brake. We thought it was a caliper stuck then released. The guys checked out the caliper and it slides with no problem. Calipers currently do not have the helper springs installed. Tech could not understand why it wore the pad out. I told him about the noise and he seems to think that the spring broke in the large air chamber. He is going to check that out. He said that a broken spring could cause that caliper to not open properly. If that's the issue would it be wise to change both chambers? They are currently making sure the pins are going to come out easily so they can determine what needs to be order. We are going to have them put the helper springs on all of the calipers. Should I just go ahead and get new pins?
Thanks, John M.

After all the problems I had with brakes I would buy new pins without hesitation.

A broken spring can get wedged and keep the piston from retracting. Not very common but the air cans are not very expensive.

The pins can be re-used if not pitted. These pics. show before and after wire wheel brushing.

The pins were heavily pitted. We are getting a new rotor for right rear, pads changed on both sides of the rear, new pins all on 4 wheels with helper springs installed and clean all slides. Will check the bushings out. The brake chamber was ok so they are going to check out the caliper.

Too much grease in the slack adjuster will hang the pads up also.

They ordered the parts but only able to find on slide pin kit. They will clean the pins on left rear for now. I found 3 kits on eBay. Those kits are pricey as high as $165 per kit. I found them on eBay new at $120 per kit. Ordered 3 kits. They will change them when I get back from my FMCA RALLY at Indy.

I think that is where I bought the ones I have in the shop that weren't needed when I serviced the brakes. I am accumulating a lot of spares for this coach. Hoses, 12 volt air compressor, slide pins, resonator, lots of air springs even a spare SW3012 Murphy's law says none of these will fail, it will be something I don't have.

Over greasing of the actuator will cause brakes to drag as well. Important to purge as per the manual when you grease it.

Broken spring in the chamber is always a possibility they break with out warning or a real rhyme or reason. Yes change both at this age as weak springs also weakens park brake application.

Well, brakes on the rear are done. When you are away from home it's hard to pay for repairs you can do yourself. New RR rotor, new pads for both sides, new slide pins for both sides, added the helper springs for both sides cleaned calipers and new seals on RR....$1921 in damages. Your at their mercy when you are away from home. It had to get done. I didn't want to cage the RR and ride with brakes on 3 wheels. As my granddaughter would say...It is what it is!

Are the front and rear caliper and pads the same?

Re: Rear Rotor Replacement

Caging the chamber does not mean you only have brakes on three wheels. That spring you cagebis for park brake only. You would have one wheel park brake with the chamber caged. To finish a trip you could cage it and use wheel chocks when parked. That being said the chamber was the cheap part of what you had done.

I wouldn't consider that price you paid to be out of line.

Lon,

On your coach they should be the same pads.

As a side note the KSR701 7173 are what most fire trucks run. High heat applications. These are hard as hammered he77. If you live in Denver and cross the divide every weekend this is for you.
the Kit 15625 PM are for normal service. Somewhat softer compound. Lot more responsive cold.
Both will work on the ADB-1560 size brakes .

Rotors, pads, pins and labor. 2 coach bucks sounds right on to me. Yes you can do it cheaper and 2K hurts but you didn't get screwed.

+1 on reasonable price for the work performed, MOT similar on my coach

I had a rear rotor lock up and sear around the axle drum? Brakes were welded to the rotar and I felt something was weird as I was in traffic but realized after I couldn't stop the coach in time and rear ended a car(a little). 1 of the few times I got nervous driving and was in edge till I made it home. 1 wheel not braking is very dangerous and needs fixed asap with no regard to price. Safety is worth the 2k$ . Coming from experience.. there is nothing like pushing the brakes and you keep moving in a 40k to 50k lb coach.. even when you hit something it just slows but doesn't just stop.
