Porsche Brembo 996 BBK conversion

[Sergmann]

I feel as though the first portion of pedal travel is doing very little. Perhaps I need to do a better job bleeding the brakes or try a replacement stock master. I was running stock brakes (non zcp fronts) with hawk 70's before this and I don't feel like this was at all an upgrade from a brake performance stand point. maybe its the pad I chose?

does anyone run any type of aftermarket master cylinder with this setup or strictly OEM E46? I am not very impressed with this setup on the track (Ds1.1 pads) and am wondering if going to a different master cylinder could help? would 996 GT3 even be a possibility? It has a 27mm piston vs our stock 25.4mm

What don’t you like about ds1.11 with 996 brembos? I run this as well and I thinks is on par within spec what endurance the pad is designed for, very comparable to Pfc 08 pads IMO.

More surface area means less pressure. You'll have to push the pedal even harder to achieve what you were already getting. This setup significantly increases the amount of surface area the fluid is pressing against.

Interested to know the part number and if everyone installed the sensors with Porsche connector? I remember EAS used to sell these sensors a long time ago.

The parts are pretty interchangeable. Just look up any non-PCCB wear sensor for a 996. Get aftermarket. Heck, a Cayenne wear sensor would probably work because length doesn't really matter. It's just the part that clips into the pad.

Or solder the wires together and heat shrink them right by the connector. You can just cut the original wear sensor wires and plug them in.

You could replace the connector on the car with a Porsche one. I'll get the part number either tonight or tomorrow.

Titaniu//MI just had the same issue as you. Ordered the same part numbers which i thought would be a left and a right but I got two of the same side. Were yours mispackaged or did we both order the wrong part numbers?

Me three. From what I can tell, I got two of the right rear pipes instead of one left and one right.

Mispackaged. Only way around this issue I have found is to physically go down to the dealer that has the parts in stock and inspecting the lines in-person.

Just finished with these. I sanded off the Porsche logos with 1000 grit, put decals on, VHT clear over it. Not perfect but it passes the two foot test and they’ll be covered in brake dust soon enough anyway. The calipers came disassembled so rebuilt with the Girodisc seal and boot kits. I used brake fluid as lube and pistons went in nicely for the most part. Couple were more difficult but they seem smooth now.

Boring black but IB is enough color for me

Nice exactly what I did.

Give me your caliper part numbers and the vehicle they're from. I absolutely need to know the vehicle because the parts catalogue can be a nightmare. I can attempt to check with my parts department on Monday. Not sure how much help they'll be because generally lines like that aren't sold through dealers. It's worth a shot.

Doing this conversion as my quarantine project, and I ordered two rear crossover pipes. However, despite ordering two different part numbers, I received two identical pipes. Can anyone confirm which one of these is wrong?

Yes, pistons are hard anodized. They shouldn't need replacement unless they're not smooth.

A word on boots - they're not that important. They're important if you want to get 100k out of the seals, but if this is a track car where you're rebuilding seals every year or 2 or if this is a lightly driven weekend car, you actually don't even need boots, let alone nice new ones. You can absolutely reuse old ones. They'd have to be really falling apart to not provide protection from the elements.

I’m in the process of rebuilding some 996 f&r, where are you guys getting new front and rear piston sets from?

I see rockauto has the seals kit

Unless they're corroded or damaged, pistons tend to last a long time if they're stainless steel or titanium. If you're just rebuilding them to refresh them, inspect the pistons and throw some seals + boots on and call it a day.

StopTech pistons aren't bad and are readily available. I don't know pricing for Brembo pistons but I would guess they aren't cheap.

I think you can get Brembo pistons from places like HRP.

Rockauto sells Centric seals, which have some inconsistent tolerances. The kits also do not include the boots, and you might as well replace them while you're at it.
I got the seals and boots from Girodisc.
