RS2 Brakes

[MPSeed]

Can anyone tell me the Porsche Part numbers for the RS2 discs, pads and sticky pads.

I have had dreadful probs for the last 7 years with vibration and/or squeal.

Also Porsche bits are half the price of Audi (plus 10% Porsche Club discount).

Any feedback on cross-drilled upgrade? Porsche Part numbers etc? Also scored discs upgrade.. are these upgrades worth it?

This is the only aspect that has blighted my love affair with my Ragusa RS2!

Hi Mike,

the upgraded brakes are definately worth considering, if you have stock brakes in need of work. I've read the kit costs about £1600 (with VAT) in UK. German price is a little lower I think.

It includes everything except new rear calipers (read front discs, calipers, f+r pads and noise parts), easy to install, absolutely stunning brake feel, power and fade resistance. Have had it for 3 years, best money spent on the car. Not even that expensive, you get a bit back by selling the old calipers to S2 or some GTI owner.

There was some useful info on sourcing Porsche brake parts for RS2 here recently:

As regards sequeaking, Porsche told me that the pads should have no copperite at all, and should be run dry. The Damp plates are essential (my RS2 came without them). However, since my Audi dealer smothered the pads with copperite (or whatever it is), I have had no trouble. It seems that the brake dust builds up and the pads movement is restricted etc. to cause squeaking. The copperite may have prevented the dust jamming the pads.

My first problem with squeaking was the use of the wrong pads even though they fitted (incorrect material?)...

Also one can get corrosion (alloy/metal mismatch) behind the caliper plates that pushes them into the caliper restricting the movement of the pads... this is a common Porsche brake problem. The plates need replacing and the corrosion removed. Porsche have done this for me.

I am not a mechanic, so if any information is incorrect, and you know better, please correct me!!!

Old thread I know. Can anyone confirm these are the part numbers from porsche for STANDARD 304mm rather than UPRATED 322mm. If so useful 'sticky'
And that I purchased wrong pads in getting 968CS pads ??

[GlynRS2]

Alastair,
I agree we need a definitive RS2 brake thread.
Requirements being the exact Porsche part nos. for all discs, pads etc. on RS2 in standard and factory upgrade specification. Also it would be useful to know what Porsche models all these parts come from.
I have read several threads on various forums etc. and the information is conflicting to say the least. Standard callipers from a 968CS but painted red rather than black? But 968CS pads don't fit unless trimed? Discs from where. Rear calliper and discs a mystery combination??
Once this is known and verified make the thread a sticky

Had to replace the rear discs and pads recently, Audi want £187ea +vat,
but after seeing a very knowledgeable Porsche specialist, and a bit of measuring with a vernier, We worked out that just like the front discs the back ones are off a Porsche 928 S4, only £80ea from Porsche, fitted straight on with Porsche 928 s4 rear pads, these are the same pads as 968 fronts apparently.

this is for standard not big brake version

measured everything because Audi EKTA says discs are,
8A0 615 601C 290 OD x 24thick,
except my rear discs measured 299 OD, and since the dealer said they would be non returnable special order i did all the checking on sizes.

Rear pads are 8A0 698 451 A
with sticky shim pads 8A0 615 231 B
and 8A0 615 231C

these numbers come from the huge bunch of German service receipts that came with my car,

if Google translates German right

then Front discs are handed as 928 S4
audi part number 8A0 615 301 B Bremscheib
8A0 615 302 B Bremscheib
think pads are 8A0 698 151 F Bremsbelae

cant find a reference for the sticky damping pads but i used ones for a 993 carrera these are round discs that fit each piston rather than the rectangular pad with the two large bosses, and about a quarter of the price. About £2-3 ea, there are 2 different sizes, and you need 4 off each, the rectangular pads are £15ea from Porsche and you would need 4 of them.

i searched around for the prices and parts because i don't like getting ripped of by dealers for having a great car, My previous cars both Lancia Integrales 8valve and EVO11 where way easier to get parts for, but also more fragile

Very useful thankyou ! Do you mind letting us know which porsche specialist as some are less than helpful if you tell them its an RS2 'Oh I would not know if that will work'

[ozonefrenzy5]

alastair,

Porsche specialist is Tom Ferguson Motor Engineers,
at Newcastle Upon Tyne, they only do work on Porsches and Nissan Sunny GTiR's ! ( they race one in northern sports and saloons series)

Would also recomend Autobahn german car specialists at Hexham,
also run an BMW M3 in northern sports and saloons series
they sourced and imported my RS2 from southern Germany,
and used to import BMW M3's.

neither local Audi dealer seem to know of any local RS2's or do work on any.

Am trying to get more info on RS Audis from a friend of a friend, he works at Cosworth, and apparently he was responsible for engine work on the RS6 and cancelled RS8 project.
