D&C Extreme Rear Disk Brakes

Does anyone have any experience with these? Mine squeak obnoxiously. From a cold start, they’re fine, but as they warm up, the squeak starts. The more I drive around town or in traffic, the worse the squeak gets. It’s driving me crazy.

I contacted D&C about this. They have nothing to offer and say the pads are custom made for this kit, so I can’t just buy a different pad. The only alternative is to purchase ‘85 El Dorado pads and have them ground down to fit.

Does anyone have a real solution or are my only options:
1) have custom pads made
2) switch back to drums?

Thanks,
Mike
 
Have the rotors checked for run out. Also are you running a disk/disk MC and not a disk/drum? And how old is the hose to the rear brakes???
 
Everything is brand new. I have about 3000 miles on the system. I’ll have to check on the master cylinder. It was all built with the intent of being disk/disk, but I will double check.

What do you mean, “run out”?

oh, definitely not. they’re in good condition.

Does anyone have these specific brakes? Im thinking the issue is specific to the design. They look janky from the start, a waste of $600. I’m wondering if anyone has resolved this issue.
 
I'm not familiar with D&C's rear disc brake kit, but when we have squeaky brakes we will start with the pads and chamfer the edges. Otherwise they really shouldn't squeak unless they have a piece of metal or a small rock stuck in them.

What material pad do they use?

Did you bed them in properly when new?

They’re ceramic pads. You don’t have a choice. According to D&C the pads are a specialty pad made just for this kit and you can only buy replacements from them.

They were. i’m sure of it. The brakes are fine for about 3 engagements, then the noise starts as they’ve been warmed up. I’m assuming it’s the metal expanding as they increase in temp. The more the brakes are engaged (think hitting every red light) the louder and longer they squeak. However, if you wait a few seconds longer and brake hard (which is a terrible idea) they don’t squeak as much, but it’s just squelched by the harder engagement.
 
It's just a GM pad. Just go to the autoparts store and get a pair of pads and try them. I've sanded brake pads before with no issues. You could also have a bent flange on your axle shaft(s). Or your caliper isn't level to the axle shaft.

Are you just using sandpaper on the backside of the pad or do you have a better process to grind them down?
 
Yes I also had to sand a set down on 3/4 ton set up with those calipers. In some cases with the rear calipers you need to keep the tit on the back of the metal backing plate as it sits in a groove on the piston and prevents it from rotating.

Did you grease the back side of pads and the caliper where it sets on the pads?

Go use them more and wear them in!
