Options on '75S Front Brake Calipers

SalParadise · 07-16-2017, 07:48 PM

What are my options for the replacement of '75S front brake calipers? I want to get the car on the road ASAP and don't have the time to rebuild the alloy S calipers currently on the car, so I was wondering what I could put on there for now that are more readily available and maybe I could find that are good/used and ready to bolt on.

Early 911S Aluminum Calipers

FS: Alloy S Calipers 72/73S, RS Carrera Turbo

Or these may work as well...

FS SC front calipers

The standard "A" calipers will be a bolt on replacement; they just use thinner pads.

So I can place any SC or Carrera front calipers on it with my current stock setup? I don't care about replacing the pads (obviously) but if I can find a good clean working pair of anything at this point while I rebuild the originals it would help.

PMB might have a restored set of S calipers on the shelf you can buy on a core exchange basis.

not to highjack, but I have been looking for a guide to rebuilding the S calipers. does anyone know of a thread?

so, on topic. I would suggest that the Carrera calipers would likely require changing out the rotors too as they are 24mm where as the SC, and likely S units take the 20mm rotors.

I would not say any. There are the "A" calipers for the 20mm rotor you have and the "wide A" for the 24mm rotors on the later cars. Stick with the standard "A" caliper.

These caliper really benefit from a full restoration by PMB. The need to be deanodized, cleaned up, and reanodized. Then they will be protected against corrosion again. The piston almost always need to be replaced. I no longer bother rebuilding these calipers, and just send them to PMB. Just like Fuchs rims, these Fuchs/ATE caliper need the hands of experts with the correct processes.
