Caliper rebuild, rotor and oad change

[Daviboy]

Just whipped off the front wheels, changed out the rotors, stripped cleaned and rebuilt the calipers, threw in some new pads, bled system and tested. Easy total 4 hours and solid brakes on completion. Another wee project bites the dust.

Hey I did the caliper rebuild on my 82 SC Targa this past summer. Replaced the steel pistons with stainless steel pistons. Should be good for another 26 years.

Ruf-Porsche, where did you find pistons for your calipers? The only ones I've seen advertised are for the aluminum "S" calipers. Or do you have said calipers?

My pistons are a bit pitted (though still leak free for now), but I am not anxious to spend $600 on 2 new calipers to get that fixed.

Narrow A calipers are the same design as S calipers but made out of steel. Shouldn't the S calpier pistons fit the A caliper?

Pelican does not list them as fitting. If they do, that would be dandy. I have wide A calipers I believe (I have an '88), but I would think (dangerous, that, where Porsche is concerned) that the pistons would be identical, and the caliper got wider.

My calipers are also "A" calipers. Got my stainless steel pistons from ZIMS. Piston were $32.00 each so for 4 pistons they came out to $144.00 plus the price of a calipers rebuild kit.

Thanks much.

Brakes are great now big difference even though old pads were 50% and only one rotor 3 thou under, although the rebuild has eliminated the pull to the right which was from the outside piston on the passenger side.
