new brakes

pae · Jan 24, 2005

Next update is to replace the brake discs (no, it never ends does it?)

Any ideas on best value, what makes to use/avoid? Where's the best deals to be found? Anything worth upgrading whilst I'm at it?

........thinking about it this might be the opportunity to fit longer wheel studs so I can use the shims I've got for the rear wheels. Anyone know how long standard wheel studs are on a 1988 924S ????

thanks .......... Phil

I think Zimmerman discs from Porshce shop ( dont forget to de-grease the surfaces), and opc pads. Not cheapest but best value for money, ie Joe Bloggs pads 8 months, Porsche pads 14 months, on the same 924 lux, and there was a difference of a pound in price. Front pads for the Turbo, which I think are very similar if not the same as '24s pads were £29 back in August.

Crikey, you should have bought a few sets. My OPC has just quoted £70 for 924S front pads, and that includes a 15% discount. [:'(]

i would second that £25.oo to £26.50 depending on the make,and the disk only cost £10 for replacement and £47.00 for cross drilled sports. I replaced mine about 2 years ago and porscheshop fitted for me, there very good but i whish i had have gone for the cross drilled sports discs and green stuff pads, oh well wheres that list [

Try Porscheshop then. They often supply O.E.M. Their's are £28.80 +p&p. I know this because there was a set on Ebay which I checked the price of before I bid, and some idiot outbid me for more than the retial price

. D'oh! You want them that bad mate then off you go.

I'm just doing a check of all the different suppliers to see the best deal.

At the moment Powermarques are best on X-drilled disks. They only do OEM or Pagid shoes. ebcbrakesdirect.com are best on EBC shoes, and for standard stuff all round it's Eurocarparts, closely followed by Berlyn. Still looking though....

Mark, why do you say you wish you'd gone with EBC green stuff - are they any better? Do cross-drilled disks add anything to the braking performance on these cars, or just look good? I don't want to pay any more if I ain't going to feel an improvement over standard disks.

i used ate powerdiscs on my 924 turbo they have slots cut in them to deglaze the pads no complaints......- http://www.eurocarparts.com/ecommerce/Search_Results.asp genuine porsche discs dont rust round the hubs but zimmermans will so paint them with vht before fitting

I have heard that green stuff are better and have less fade, under heavy braking i can feel a little fade, i know this is normal but again i have heard that it is less with green stuff, and x drilled disks look better, yes im a poser [8D]

I would also second the comment about paining the middles with VHT paint on the disks, halfords have a good range of colours although i keep them silver myself. It's one of the only things that halfords is good for, soucer of milk table two.[

No need for x-drilled or grooved discs on the road - grooved discs will make more noise under braking, & drilled discs are prone to cracking.

I wouldn't expect Porsche pads to fade on the road, not unless you're using the brakes too hard

Their standard pads are a much better spec than most manufacturers IMO.

The Pagid FR pads are OK, (I believe pagid make the Porsche OE pads) but the ones I fitted had a nasty soft covering on the rear - this made them hard to get in & out of the calipers.

I fitted EBC red ceramic pads front & rear to my 924S - about £140 all in. These have lasted through 4 track days and around 3000 road miles & have loads of life in them. No fade on track either.

One thing I have noticed is that brake pedal travel seems to get longer as the pads wear - anybody else seen this?

pae · Mar 30, 2005

Should I change my brake pads when I fit new discs? Mine have loads of life left in them.

I think you are meant to do this, but if I don't need to that's great news (I can spend the money on other goodies [

no need to replace the pads

- In fact when using uprated/race pads, I've read it's better to bed in new discs with old pads

usermjg · Mar 30, 2005

i know this goes against what "edh" said but i would replace the pads if you are replacing the discs, even if you have plenty of meat left on the old ones, its piece of mind that you have done it, and they will bed in differently and the price of new pads from eurocarparts isnt going to brake the bank, brake get it.
i know i reply alot with tognue and cheak comments but for me it tires brakes and steering first, and they must be top notch, and the rule of thumb for me is if i can change it to maintain it do it.

Well I was going to get EBC pads when I buy some new ones, so they're not that cheap. It's just that if I can put that off until I need the pads I'm OK with that.

Thanks guys, 2 answers, both conflicting - I thought this forum was supposed to help me[

Changed the pads on my 928 recently. Apparently the best to use are the OEM ones as last longer. Discs - zimmerman apparently best and as has been said - cross drilled just noisier with nothing else to add for road use. And never buy from an OPC they charge you through the nose!!

edh · Mar 30, 2005

here's a couple of places that I got the info from

http://www.mintexracing.com/prodspec/bedding_req.htm

http://www.stoptech.com/whitepapers/warped_rotors_myth.htm

pads are servicable until they reach their wear limits - I find the pedal on my 924S gets slightly longer as the pads wear - that's about it. The pads are reasonably easy to change at any time, so it's not like you'll be saving a day's work by doing it all in one go.

As for manufacturer - I'd go for OE Porsche unless there was a good reason not to - Porsche specifiy good quality pads that will stand up to sustained heavy braking - even moderate use on track days. The Pagid fast road is similar I believe, slightly cheaper, but has a nasty soft backing material that made them harder to fit. ( I fitted them to a car I was selling)

I'm running EBC red ceramic - I don't think EBC would recommend greens. These have lasted around 3000 road miles and 4 track days, and are just over half worn.

good links those, thanks.

Chaps, I've got them at last - ATE disks (OEM). Do I need to de-grease them in any way before fitting? And should I paint the centres? From earlier comments I suspect not with these, and I don't want to.

Phil, I am disapointed. One minute I'm the bible and next minute you have to ask me if you need to degrease the disk. Every pair of disks I have ever bought, and A32NFX had four pairs of disks and three pairs of drums, had a corrosion resistant coating the like of which I would not want to contaminate my pads with.
