Generic Brake Kit Need Help With Caliper

DanDokken · Jul 3, 2025

Hello
My 65 Coronet came with a generic disc brake kit installed long before I owned.
Have a sticking caliper now and am trying to find a pair. This part # doesn’t show on Rock Auto. I am a GM guy doing my first Mopar so not familiar with calipers. Are these A or E body?
I cannot take credit for blue paint

73- A body, F body and some others without the pin type caliper which uses a D39 pad. Yours uses, like mine, the D84 pad. The D39/84 are industry numbers for pad style. When you get one, make sure the piston diameter matches yours. Don't want different sizes side to side. E body uses the D39's. Have you tried cleaning off the sliding surfaces and lubing with a very small amount of brake caliper spec grease or anti seize? Maybe there is a burr holding up the works?

Mine started doing this. Just unbolted them, wire brushed the sliding surfaces, a tiny bit of silicone brake grease, and bolt back together. Problem solved.

Another good test is trying and push them back with a c clamp. Compare the difficulty in turning the clamp.

I have the same calipers in my 67 Charger. I had replace them as the seals were all dry and rotted from sitting for years. I has to use calipers from a 1979 Dodge Aspen. I ordered one from a v8 car and they fit fine.

Are they any better than the 79 Aspen calipers? Maybe I can try them next time I need to replace the calipers.

I don't know how they'd be "better" - what are you expecting to be "better" ?!?!?! It's all about how they fit - where the hose attaches and where the bleeder is - there is no "better".

One thing you do have to take a good look at with these reman calipers (they're ALL remans these days) is the bleeder screws and seats. I had FIVE calipers with bad screws and seats before I finally gave up and bought a pair of bleeders and refaced the seats myself (with a drill bit and my drill press I might add!).

Also, some will have phenolic pistons as opposed to steel. I guess there's a difference but it seems to be based more on which style they are as opposed to who makes them.

Honestly, just buy the cheapest one's you can find !!

Mine started doing this. Just unbolted them, wire brushed the sliding surfaces, a tiny bit of silicone brake grease, and bolt back together. Problem solved.

I also agree with this. A "sticking" caliper might not be because of the caliper itself. AND even if it is, why not rebuild it ... give it a quick hone and a new seal and boot. At least you know everthing else on it is good!

I say better in that sometimes improvements are made, but I guess it's probably the same part. I just worry about those clips they used to hole the caliper in. Seems to me pins are better.

Oh I get it ... you're one of those guys that wears a belt AND suspenders, right ?!?!?!

There are or were hundreds of thousands of cars on the road with calipers held on by those clips. Get over it !!
