Brembo calipers, like those that should be on your 944, don't have internal fluid passages. They have an external tube that goes between the caliper halves. They can be split and reassembled with ease. However, this is usually unnecessary. Pull the pistons, seals, bleeders, and crossover tube and send out to get cleaned like George says. Reassemble with new seals ($10 each) when they return and you have nice, new-looking rebuild calipers.

Oh, and get them repainted black like they were originally or you'll be "that guy".

Or just soda blast them and leave it at that.

Glass bead works just fine too. They are easy to flush out afterwards.


I found the right hot tank soak eats most paints off anyway. 2 hour soak at 60C to soften things up then a hour of ultra sonic to buzz it off.

Thanks. That notched business at the end is also something stuck in my mind. Doesn't apply to my fofo

Scraped off with a razor blade when paint initially set up. Finished off with some 1000 grit sandpaper.

PORSHE lol

As everyone says splitting early ATE calipers is a no-no. Though the seals are once again available.

VAg, I found a good source for just seals at Suffenhouse (or something like that) in NJ. good prices on aluminum pistons.

Yes, that's them. Nice part is you can buy just seals or just pistons or both. Most "kits" I've seen are $$$ because you have to buy both even if not needed. When I ran the 951/964 calipers on the SC I had several sets of just seals in the track bag.

I have a set of spares I bought years ago but never cleaned them up or used them. I took them apart this weekend to see if if can drop them off at the machine shop for cleaning. Had to be a little strategic about taking out the Pistons. Too off one side and then took off the connecting line to get the other side apart. I used an old pad and my collection of clamps.

One thing.... The frames that hold the pads in...they are MUCH tighter than the ones on my car. They are held with 4mm Allen bolts I couldn't get out. If the shop cannot get them out, is this something I should worry about it? If the pads are tight in the frames will that cause problems? I was thinking I could try and bend them a little or file them a bit. Maybe a good cleaning would make this better.
