Rear Brake Pads | 1981 Pininfarina

[18Fiatsandcounting]

The brake pads sizes (front and rear) were the same for all the production years from '66 through '85. What did change is the style of the anti-vibration spring, so 1980 and later was different than the earlier ones.

Are your Napa and RockAuto pads too big, or too small? If too small, do you have the anti-vibration pad in place?

If the pads are too thick even after compressing the piston all the way. You have to screw the piston in using the slot on the face of the piston. It is not always easy to turn the piston but the only way to get new pads in.When done the groove beside the slot must be on the bleeder (top) side in order to bleed the rear brakes properly.

I've been having no problems with the pads from Autozone, OReilly or Advance aside from having to remove the plastic anti-squeal plate and use the anti-squeal coating instead which has been the case on more legacy and new vehicles than just the 124. And that's even after putting new rotors on that were fully machined and brake ready which many are not.

You have to watch out for some rotors that are not machined to thickness and still need to be put on a brake lathe to be milled down to final thickness and trued up.
