Does anyone know if these are easy to rebuild? Do they have rebuild kits? Should be a couple of o-rings? Mine is failing, my rear brakes lock up once in a while. Attached a picture of it. 73 Dodge
there might be rebuild kits out there, you may want to disassemble and make sure everything is in decent condition. I had one that the pistons were all corroded and wasn't worth rebuilding. nice thing is this style is common to pretty much every GM from the 70's and 80's and new replacements can be found easily
