EBC disk brake opinions

Duncan said:

Hi, I have a bike with Avid cable pull disk brakes. I think they came off a 2000 Giant ATX 890.
The OEM pads performed perfectly and wore acceptably.

The other day I replaced them with XC EBC pads, the front lasted 12 km and was down to the metal.
I got a free replacement but the same thing happened again, it was from a completely different
batch as it had a redesigned backing plate. I had a 12 Enduro race the next day so my only option
was to go back to the OEMs. They still worked perfectly but are within a bees [censored] of the metal.

I haven't had a chance to get back to the shop yet but wanted to do some research before I did.

Has this happened to anyone else? Did you find out why?

AFAIK the rotors are good and straight, with the wheel spinning I can pinch the rotor without
shredding my skin.

The calipers are straight, as evidenced by the wear and stopping power of the OEM pads. The
Caliper was set with the necesary 1/3 2/3 spacing on each side.

The EBC pads wore diagonaly but that was due to them wearing to fast to adjust the stationary
pad. (the first and second set wore the right and left pads down respectively without affecting
the other).

The dead pad looked extremely pitted as if material was coming off in chunks.

I have a friend who is a 'brake pad engineer' for bendix who says even with a totaly screwed
caliper/rotor a pad should not do this (on a car anyway).

Been using EBC on my Hayes Mechanicals for a couple of years. Zero problems (except with the gold --
which squeel at the drop of a hat and don't stop very well). You didn't say which pad (red, green,
or gold). The red don't wear as long as the green and as far as I could tell in my riding, all you
get is slightly better fade resistance -- but I've only really seen the difference on long steep
road descents in the mountains when I come up on a slow moving car 🙂.

I've always had my pads last more than a season -- and I ride a lot. Except when they get bad oil /
grease contamination, and that's not EBC's fault!

In comparing the EBC green to Hayes pads, they both last too long to get a comparison there. The
EBC seem a little more resistant to squeel and oil contamination, but fade slightly more than the
Hayes on long steep descents or where I need to ride my brakes -- but not enough to make me worry
about being able to stop. I've swapped pads mid ride just to get a better comparison (they're that
close 🙂).

I've heard of EBC pads breaking up on cars. Don't see why a similar friction material shouldn't do
it on a bike.

I've had problems with brand new pads getting wet & muddy and sloughing away really fast like you
describe. Someone posted recently about a "glaze" being built up on the pad surface that protects
it. I don't know about that, but there is the usual claim that pads need to 'wear in' with 20 or so
hard stops before the performance is any good. Maybe that's what it is? Maybe the 'glaze' is needed
in part to prevent water having it's wicked way with delicate new braking surfaces.

Pad glaze is a bad thing - that's what stops 'em from stopping you.

Never had any problem with my disc pads wearing fast, but they take a helluva lot more than 20 hard
stops to bed in, even with the use of wet mud (which works wonders, BTW).

Shaun aRe bedding in a new set right now so I can stop if I need to coming down off Snowdon,
heheheheh........
