One of ebc discs appears to have warped, so i'm looking for some new discs. When I had standard discs and pads, they tended to fade after just one hard stop. What I would like to know is whether it was the discs or pads at fault?
My red stuff pads still have quite bit of life left on them. Would standard discs be ok? I'm not hard on the brakes, so i'm just looking for a desent road setup.

Any info appreciated!

anyone?

What type of fade was it? Generally:-

If the pedal was firm, but no stopping power then it was a pad fade.
If the pedal went really soft, long travel and no stopping power then it's the fluid

There are a few things that cause fade, one is the heat getting put back into the brake fluid, could possably do with a change? you can also add braided lines which should give you less flex.
The second is that its the gasses that build up between the disc and pad, basically stopping them connecting properly, grooved discs help here, and possably a different type of pad.

Pedal was firm with no stopping power.

you've over heated the pads in that scenario then......................

use a better spec material, fit cooling ducts or use your brakes less....................LOL

I have just changed my brake fluid in an attempt to fix my brake judder problem. No different. Looked at my o/s/f brake disc and I think I have confirmed that the disc is warped. On the disc, I can see where the pad has been making contact. There appears to be a 15mm gap either side of the pad contact area, towards the outside and middle of the disc.
Any ideas?

changing fluid can have no impact on a "judder" of any type.......................

its possible you have a (partially) seized caliper or similiar issue, pads trapped in caliper??
suggest a strip and check at least to confirm and sort the fault..............

Stripping them down when I get the new standard discs and pads that I have ordred. (not from subaru might I add!)

It only happens when I generate some heat. Driving around town and up to say 60mph is fine. Braking from above that causes some judder. I thought it might be glazed pads so, I warmed them through and did some firm braking from 90 - 40mph several times. This actually made the problem worse and felt as if something had over heated. I could feel it even at 20mph until things cooled down. Thats was why I changed the fluid + it was due for a change anyway. I don't brake hard at all, and this is the first time I have ever experienced any kind of braking problems.
Just hope that the new discs that I have ordered will fix the problem.

So would standard discs be ok with red stuff pads?

will work fine, although redstuff are not my choice...................

Now i'm thinking that my pads are worn. Do these look a bit low? (sorry for the quality, took them with my phone).

difficult to tell from those pics, but appear to be fairly low..................

It was the discs that caused my juddering problem! Only had them on for 8K! Pads looked quite low aswell, so after I went for a short drive with new discs fitted (to confirm if it was discs or pads), I fitted some new pads.

Now, bearing in mind that my new discs and pads are standard (lucas parts), straight away I could feel that I had a more positive brake pedal, and after 10 miles of gentle braking to bed them in abit, they felt so much more positive than the ebc cr^p.


I know ebc red-stuff pads are not supposed to last that long, but I didn't expect the discs to follow the same trend! Warped after 8K (well actually 6K!), £350 for brakes that only last five minutes, and don't even work that well either. If I had done a few track days, I could understand this, but not for general driving.
I bought my lucas discs and pads from grahem goode racing via ebay, for ..... wait for it..... £99!

I vow never again to buy ebc products again. Yes buck, i'm sure those track tests that ebc have carried out are very encouraging, but, in the real world (which actually counts) EBC Red Stuff Ceramic Pads and Groove + Dimple Discs were noisey from day one, didn't feel any different from my original setup that came with the car, and lasted 8K of normal motoring. FACT!

Here's what left of my discs and red-stuff pads:

Only took me around 2 hours to change both sides (and had that short drive in between), it was the rocker cover gasket that took the most time today. 3 hours! It wasn't really that hard to do, just very time consuming with the limited space.
Still, a successful day in the garage!

Did you check the condition of the pistons in the calipers? As long as they are moving freely then they wouldn't be the reason your disc and pads have worn so quickly.

What sort of driving did you do over the 6-8K?

I don't think I use my own brakes any harder now than I did for 2yrs on the OE setup and they lasted ages. I fear the aftermarket EBC stuff I'm running now won't

Pistons were fine. As for my driving, I have always averaged between 19-23mpg on my sti 4 which has stage one mods (green filter, decat exhaust system).

New pad thickness vs old pad thickness:

Hopefully I'll have a look at mine at the weekend, although the garage said they looked fine a week ago. Most of my driving is motorway, so I hardly use them day-to-day. They're then interspersed with some fast B-road driving so they tend to get abused on a couple of times per week and then over just some short distances.

If I'm climbing or biking at the weekends then they'll get some serious abuse over longer distances (40-70 miles).

Thats probably about the same use that my car gets.

I wouldn't call ebc's products 'dangerous', just poor, in all areas.

A bit cheaper than 'Official Subaru' items. They were relucant to quote because its an import. He came out with, ' oh yea, import 4-pot brake's are different to uk spec 4-pots.' Kn&b! Quoted me £425 excuding fitting.
