69 Front Caliper Restoration
« on: March 06, 2022, 09:15:25 PM »
Looking for tips on caliper restoration as to the do's and do not's. Can they be safely bead blasted, etc... Short of installing on the car, is there any way to bench test the pistons to make sure they're not seized up? Any and all tips will be much appreciated. Thanks in advance.

When all is said and done, paint them black, just like the factory did. Blue caps on the bleeders.

Learning more and more about less and less...

Gosh, I was looking for photos of my Pacer caliper rebuilds I did a few years ago, Now I sure think the single piston versions are very DIY friendly and the seal & Oring kits are very affordable, seating the seal and installing the piston past its installed o-ring with out injuring the Oring are but a few of the details I can vaguely remember. I can not remember if I had to polish the bore ever so slightly, new bleeder screw, new mounting bolts and slider o-rings and a splash of black paint, etc.

Calipers should look something like these when done.  (Don't look at the bolts on the upper ball joints. I couldn't find anybody to rivet during Covid)...Joe

Thanks for all the pics, they're very helpful. Can anyone chime in on the actual process of cleaning the calipers and testing the pistons to make sure they're free? Thanks again.

I can't believe there's not a GOOD youtube video on caliper rebuild. This one will give you an idea. Use a large "C" clap & wood to move the piston back into the caliper. Maybe somebody knows of a better video....Joe

Air pressure in the rear to blow the piston out for rebuild... hone the cylinder and install the kit. They are very easy to do.
