Decided to rebuild my calipers as I had noticed that many of the dust shields and heat shields were deteriorating pretty badly.

I ordered new bolts, brake pads retention spring and kit, dust shield and gaskets etc.
well, should have ordered pistons too..............
Anybody know of a good place to order pistons??

 

Used a $10 bicycle pump to pop the cylinders.

 

Anybody out there that replaced their calipers and have a spare 28mm piston ?

 

I've had difficulty sourcing Brembo pistons. I do recommend Zeckhausen Racing http://www.zeckhausen.com/ . They sell Stoptech which fit the Brembo caliper. The issue is the height of the piston. Stoptechs come in either " Short" or "Tall". Work with them to figure this out. Service is excellent.

 

Thank you. I bought the seals and dust kit from them. I will call and ask about pistons

 

Tor - I had my calipers rebuilt late last year. They found a couple of cracked pistons and a couple more with pitting. I neglected replacing the degraded dust boots too long, so that was my fault. Porsche doesn't sell replacement pistons, but will sell a whole new caliper at an outrageous price. However, the pistons in the street 996 GT3 are the exact same pistons as those found in the 996 GT3 Cup, and Porsche motorsports sells replacement Cup pistons. So my shop (Nolaspeed) bought the Cup parts to complete the rebuild.

I don't know if Nolaspeed kept any of my old pistons. If you are desperate to avoid buying a new piston set, I can ask them if they still have my old pistons, and which ones are reusable.

 

I had same thing happened to my calipers and this is what I ended up replacing them with.

So far so good...

 

Thank you

 

Any links with instructions/video on DYI caliper rebuild for 6gt3?

Step. 4: I was not able to remove by hand so I used a bicycle pump and the plastic soft tip per photo above into the hydraulic port. Used brake pads and pic/ screwdriver handle to block off cylinders.
Left one cylinder free to pop. So I did one cylinder at the time and move myself around to each one. Trying to pop all 4/6 out at the same time proved to difficult.
One cylinder out, clean, change gasket and dust cover, insert, block off and moved to next one.
Used a mechanics pick to remove dust cover. Used a plastic sharp tip pick ( interior plastic removal tool) to remove the gasket.


I removed the brake line at the caliper. It was easy. Then used an arrow stabilizer tip to plug the brake line. The steel line at the caliper is very small so the soft rubber tip which I found at a sporting store worked well to plug the line.

I say the project takes about one day including bleeding brakes after.

 

Thx! Looks like a good little project and not too complicated. Putting it on my list.

 

My shop identified those pistons to me as a 2nd option to the Cup parts. They had done many rebuilds with the Cup pistons, but had never used those SS pistons and therefore couldn't vouch for them. It's good to know that you got a good result with them. I may try them if I ever need to replace pistons again.

 

You can get a brembo rebuild kit from PMNA and that includes everything you need including the pistons and yellow zircon inserts

 

Thanks for the help.
Zeckhausen supplied the single piston.

 

New brembo rotors all around.
