Reply to "Seeking advice prior to rebuilding the brakes for 1332"

I just want to add something about the parking brake mechanism:

The parking brake is self adjusting by means of a ratchet mechanism between the two pistons. This mechanism allows for compensation of brake pad wear.

The assembly shown in Larry`s photo contains a small collet with a very fine thread:

On my car the parking brake was not working because the thread on this collet was damaged - no pressure could be applied to the brake pad when the parking brake was pulled. Obviously, someone had tried to push the rear caliper pistons back without turning the outer piston by 45°.

So if you separate the pistons as shown above, please check those threads for deformations:

Unfortunately, I couldn`t find this collet anywhere. So I had it re-manufactured.

If anyone needs this collet, please contact me for technical drawings.
