Porsche Brembo 996 BBK conversion

Fake news

[jbfrancis3]

I’ve read that powder coating calipers is not recommended for calipers. My preference is to powder coat my calipers due to the fact that I have a great powder coater nearby. However I am tracking the car so I am concerned about its ability to withstand the heat. Anybody successfully powder coat their calipers for track use?

Who says that?

How could the calipers handle the temps of braking but not baking? Are you baking ?

I have to say that this modification has made me hate my car. The squeal makes me avoid driving it. It is so intrusive. Does anyone know of anything that can be done to fix this or if this is also an inherent problem with Brembo BBK’s in general like this set,

Make sure you are running updated pads and spring kits. Lube all contact surfaces but don't go nuts. Get the sticky dampers that sit on the back of the pad. Look up my post of a Porsche bulletin about why brakes make noise. It's not unique to this mod.

Also remember these pads and calipers were not engineered to function with our rotors. Results will vary. My car squeaks like crazy with genuine Porsche pads. Oh well. The braking is far superior to stock I live with it.

Check your clearances and make sure nothings rubbing

I have these brakes on my car and do not get any squealing. Are you running dampeners? Maybe it is the pads you are running?

Yup those are the numbers.

I actually just saw a Low milage 28k set in near dam mint condition on eBay. Shouldn't need rebuilding I called up the supplier directly and just bought them.

Anyone have any tips on were to source 996 Rear set 996352421 996352422 ?

Are those the caliper part numbers? (responding via mobile, away from my laptop)

If yes, eBay always has these available. So long as nothing major is wrong with them, you're good. You're rebuilding and refinishing them presumably, so the risk is minimal IMO. eBay is where I got mine.

OK, mystery solved -- I heard back from Eric at Rally Road.
Those washers were shims for the caliper brackets, not crush washers.
.
This reminds me that I forgot to update the following:

How well did the Girodisc boots seat into the caliper? On my rear calipers, the large boots fit fine, but none of the smaller ones will seat correctly.

I was able get the smaller boots to seat. After Girodisc checked if the parts were correct (they were), the suggestion was to use a block of wood and a c-clamp. I used the Girodisc pad spreader, which got them to seat all the way.
One important detail is the boots need to be installed dry. I got a little assembly lube on one of the boots, which kept popping off, even with pressure. I cleaned it up, and it stayed seated.

Isn't it a banjo bolt into the caliper? The crush washers should go on either side of the eyelet that the banjo bolt goes through.

[elbert]

I have the Rally Road lines and brackets for the rear brakes. Included in the mix were 4 copper crush washers. Any idea where they go?
I tried in-between the line and caliper, but the gap is too big and the washer floats around.

(I can't remember if Rally Road included instructions -- if they did, I can't find them, and I apologize if this was covered in them.)

Yeah the dampers are extremely essential to knocking out the vibration. I live with the squeal so I don't have them rusting inside my calipers.
