I have a 1988 CRX SI, The problems 1: at first it was really though compared to the 94 Civic LX I drove, but it shouldn't be hard. (I'm thinking brake booster) 2: I recently had to change the rear wheel bearings and in the past I used a C-clamp to push the piston back in the caliper to put it back on the rotor with the pads. Only the piston would go back inside the caliper at all! (I'm thinking maybe the calipers are going bad? or is this a brake booster issue?) 3: I know my pads need to be changed because they started squeeling, but they shouldn't always be squeeling even if I'm not even touching the brake pedal. Could this be a issue with the calipers? Slightly warped rotors? (they look fine and when i press the brake they don't shake much but it seems like the brakes squeel just slightly louder at certain points of rotation. (I'm not too sure) I'm not sure if it is the Brake booster, calipers, or what? My car has slotted rotors in the front ( I was told they were brembo) Where can I purchase a set? Can anyone help me?
