h4nsm0l3m4n Posted January 25, 2011 Share Posted January 25, 2011 I've been having a hard time getting my brakes working at 100% again. My car has been running 83 280zx rear calipers and rotors for 2 years now without incident. However, I recently discovered that one of the calipers (on the drivers side) was leaking. I bought a reman unit from autozone but found that the brake line inlet thread was the wrong size! It was tapped for 3/8-24... I returned it and bought another set from a different store. This one was a reman from Wagner. I installed it just fine but when I went to bleed it fluid would come gushing straight out the bolt for the emergency cable. I returned that one and bought a third caliper from A1 Cardone. This one installed bled well initially. However after a few days I noticed that if I would drove the car a sizable distance without pumping the brakes the first pump would basically go right to the floor. Checking the caliper I noticed some moisture on the lower half of the caliper, I'm suspecting a leaking piston. With my back story stated I have to say I'm at a bit of a loss as to what to do. Am I doing something wrong when I install them or is it normal to get crappy calipers when you go to buy a rebuild? Is one brands of reman calipers that are "better" than the rest? I can keep buying and returning these calipers but I'd like to get this right and for headache to be over. Quote Link to comment Share on other sites More sharing options...
padam07 Posted January 25, 2011 Share Posted January 25, 2011 Sounds like you might have a bad master cylinder if the pedal goes to the floor initially. The leaking of the caliper just sounds like you got another defected caliper. I guess you are just having bad luck with them. Quote Link to comment Share on other sites More sharing options...
