EBC Brake Discs any good?

Post Wed Jan 12, 2005 3:41 pm

Was thinking of getting a set of EBC brake discs to replace the standard solid dics on front rather than going to the hassle of getting new callipers for vented discs.

Has anyone get any experience of the EBC brake discs?

Post Wed Jan 12, 2005 3:51 pm

A friend of mine has used them no problem on his cavalier, but I've heard too many people say bad things about them to recommend them

Do ATE make a non vented disc? if so go for that!

EBC brakes are a bit naff really

325i front brakes will work much better are arent any extra hassle to fit

I'm currently running vented EBC grooved & dimpled on the front of my 325i, and they have now warped after 10 months use. So I'm not that impressed with them, also they are a bit noisey.

Does anyone know what the ATE power discs are like, and whether they are noisey when braking??

Sounds like I should stay away from EBC discs. I am concerned about getting vented disc callipers off another E30 that may be knackered, as you won't know till the're fitted

Have you cheacked they are def. warped and its not just pad transfer/build up on the discs? This can happen esp. if you leave the brakes on when stationary after using them hard with discs still being hot

As for ATE discs I don't find them particularly noisey, but you will get _some_ sound from any grooved discs
It's usually the pads that make a lot of noise, and the better they work the more noise they seem to make in general

My EBC discs were the same after about 12 months. Only warped a little but had stress cracks all over the face, due to heat I think. I didnt push them that much so I wasnt impressed.
They were noisy, but I would say all drilled and grooved discs would be. I was told EBC were louder than others.

If I stay with standard brakes, I will probably get some ATE discs as Ive heard good things about them.

Did you fit EBC pads as well? I have found the warped disc feeling to be caused by the early EBC pad material on the Greenstuff pads. Changing to Redstuff improved things but material still built up on the discs (280mm with Wilwood 4-pots). They have now changed the reds to a ceramic quality.

ive got ebc grooved discs and have had no trouble with them in the last 14 months ive had them, i used green stuff pads at first and they where crap, i got bad fade on them, now i use feredeo pads and now its all perfect, if anyone is looking for a good pad i would reconmend feredeo pads

Definitely warped and yes I am using the green stuff pads, which i think brake really quite well appart from the vibration from the warped discs.
But if it is the pads that warp the discs then they both are gonna go in the bin.

It looks like I will go for the ATE power discs but not sure on the pads either :
the PAGID fast road pads (which I've heard they squeel after a while) or Ferodo, mintex.
Or can anyone recomend what would be good with the ATE power discs?

Post Thu Jan 13, 2005 9:59 am

Ferodo DS2500, these will squeal too though, I've heard Mintex are even worse for squeal.
Pagid are bloody pricey - no experience with them

messed up this post

. how do i delete it? what i meant to write is below. sorry

Post Thu Jan 13, 2005 10:03 am

i'm pretty sure standard bmw discs are ate anyway. so they've got to be pretty good. the only thing with the power discs is they eat pads(as do any grooved disc) but have only heard good things about them. i've got genuine discs on mine and have had no probs. the only difference is bmw paint the hub part of the disc grey. well worth doing, looks better than rust

Post Thu Jan 13, 2005 10:04 am

Are Ferodo DS2500 pads like fast road pads, similar to the green stuff pads?
Plus where can I buy them??

Post Thu Jan 13, 2005 10:11 am

i've used pagid fast road pads before and they were spot on. you can get them from gsf

Post Thu Jan 13, 2005 10:14 am

i cant remember the code No on my ferodo`s, but i think there is a fast road and the rally ones, ive got the fast road ones, green stuff pads are good for hard breaking now and then, but you try breaking hard in them quite a few times and they soon over heat and fade badly and thats through experince

Post Thu Jan 13, 2005 10:15 am

nothing to do with this post, sorry but used to live in steeton when i was i bey tvrtasmin. moved to devon in '84. we lived in pot lane. first time i've seen it anywhere since we moved. brought back some memories. good roads round there. mega cambers. spent loads of time in the old ww2 bomb factory down the road as a kid. i bet thats houses now init

Post Thu Jan 13, 2005 10:46 am

ferodo ds2500 are fast road, and ferodo 3466 are light competition/rally compound.

i run the latter with ebc turbo discs up front and my discs also have microfractures so i wouldnt recommend them at all...will prob try black diamond next or tarox or brembo

Don't know why anyone would want to run anything other than ATE discs really - they're cheap as chips and do the job!
I would advise against any drilled discs as these will just crack

DS2500 are a track/race pad that can also be used on the road as a fast road pad, they supercede (and from all reports I've heard are much better than) DS2000 which I know some BTCC drivers used
I think, but dont quote me, Ferodo make a seperate fast road pad - not sure what its called, might just be DS???
DS3000 is a full on race pad that requires warming up before use so is unsuitable for road use, they offer a higher level of friction, but will eat discs

I don't know any thing about the 3466 that Karan uses apart from that they are also a race pad that can be used on the road (I think) and I've heard a couple of people give them the thumbs up

The part no's for DS2500 on the 325i are
Front: FCP303H
Rear: FCP296H

Quick follow up about Ferodo pads
Looks like fast road are DS performance - friction coefficient. about 0.45
DS2500 0.5
DS3000 0.62 when warm

DS2000 had a friction coefficient of 0.42!

I've read this one before that is why i asked if Greenstuff pads were used as they and the early Redstuff used to deposit pad material on ANY disc not just EBC.
If anybody has had problems with the early EBC sport orientated pads, EBC will usually exchange them FOC.
