EBC rotors - problems and alternatives
Discussion
Eyup,
I have EBC grooved and dimpled GD150 front rotors, they are less than 3 years / 10k miles old and need skimming - if not replacing, depending on what we find.
I've found other threads where people are having EBC rotors skimmed, so is there an issue with them?
Has anyone found an alternative to the GD150 for a Griffith (Sierra 4x4 I believe)
Anyone fitted Tar-Ox?
Thanks
Ian

From my experience with EBC rotors this is fairly common to all high performance discs. Are you using uprated pads as well? If so this will likely cause additional heat which clearly affects rotor life.
The same by the way is true of Tarox (in particular) and Black Diamond. Had them all and they all have limited life spans and dependant on the type of disca can be skimmed easily.
Unfortunately its the penalty for having more stopping power.
I now stick to standard rotors but even they need skimming with uprated pads on a biannual basis.

t product and even worse service/attitude i will never buy their discs again.I've had TAROX discs (sport) grooved & drilled which have lasted well after 3 years & several track days - also fitted EBC Ceramic reds at same time which are also holding up well. Cost a bit more to start with for a stnd upgrade but worth the money long-term.
Never tried EBC discs but pads always been okay on several applications i've used them on

I’ve just put EBC GD558 discs on the rear with Red stuff pads. These are same size as original, but grooved and dimpled.
I’ve never had dimpled before and there is a ‘shush-shush-shush’ noise as the wheels rotate. I can’t find anything touching that shouldn’t be. I think maybe it’s the edge of the pad passing the grooves and dimples.
I’ve got AP discs on the front. They’re drilled and grooved, but don’t make any odd noises. Is it an EBC thing, a dimples thing, or what could it be?

Is it only happening on one side or both?Assuming it is not tyre/wheel related then maybe one of the discs is not sitting flat on the hub face.
Calliper's painted, no sign of marks to suggest rubbing anywhere.
Discs properly seated too.
I had this - turns out it is air being compressed as the groove passes under the pad.
Sounded like spokey-dokeys on a bike, and seemed to get twice as fast (ie. 2x as many/sec) when I applied the brakes.
Goes after a little time/wear.
I did a track day, and it had gone by the end of it - no spokey-dokey noice now.
It is a standard thing, and will go - worry not.

I've also just fitted EBC grooved and dimpled discs all round during chassis overhaul and have the same noise, however I've used Mintex M1144 pads not EBC ones. I initially went round and took all the brakes apart again to check for problems but none found and when Steve Guglielmi set up the suspension he said that the noise was normal for the type of disc.I’ve never had dimpled before and there is a ‘shush-shush-shush’ noise as the wheels rotate.

So the fix is to drive it like I stole it.Do 
Well that's a relief.
I upgraded the fronts a couple of months before the rears. I'm still puzzled why the fronts make no noise, but the rears do.
Fronts are 300mm grooved & drilled rotors on alloy bells with AP Tuscan 4 pot Calliper's. DS2500 pads.
