James B Posted June 23, 2010 Share Posted June 23, 2010 Hey guys, Just wondering if anyone else has this problem. Replaced my discs and pads all round with EBC Turbogroove and Yellowstuff pads. I get a funny grinding noise that varies as the wheels rotate. THought it might have been the bearings so took it in to Abbey for them to have a look (feeling like a clueless muppet). Apparantly its nothing to worry about and Simon (awesome helpful chap) said its just the pads picking up on the slots in the discs. I've seen a few posts crop up about the compatibility of yellowstuff and them only being designed for flat discs. Does anyone else get this noise with their brakes? Specifically the same brakes that I have? It's bloody annoying as noises go and I'd like to understand it more / know if anyone else in the same boat as me. Cheers, James P.S On a totally separate note - big thx to everyone at Abbey. They really do live up to their reps for being so helpful. I'll defo be returning to them for any work that needs to be done. Quote Link to comment Share on other sites More sharing options...
chippychip123 Posted June 23, 2010 Share Posted June 23, 2010 Alright your a Tonbridge boy, same here. wot colour zed have you got and I,ll keep a lookout. On the brakes issue I've just ordered some EBC turbo grooves but with DS2500 pads. So I can let you know when they get here if they do the same Quote Link to comment Share on other sites More sharing options...
ikarus Posted June 23, 2010 Share Posted June 23, 2010 I get a funny grinding noise that varies as the wheels rotate Can you elaborate on the description a little, is it doing this during braking from speed? is it only when the brakes are applied?

maxi-glasgow Posted June 23, 2010 Share Posted June 23, 2010 When I put grooved discs and better pads on my Saab a few years ago there was a definite difference in noise level when braking over OEM, and by that I mean louder..so I would imagine this is all your hearing.

Those yellowstuff pads are really damn abrasive, you will probably find once they have worn the the discs away they will stop grinding. Do you find any benefit from the??? under braking??

Chris`I Posted June 23, 2010 Share Posted June 23, 2010 If Abbey have looked at it and are happy with it, then I wouldnt worry. As the others have said, grooved discs do make a bit more noise, so it might just be that. Quote Link to comment Share on other sites More sharing options...
GT4 Zed Posted June 23, 2010 Share Posted June 23, 2010 The grooves explain the noise in part and also becos' yellow stuff are more aggresive with higher metallic content. I get this on my slotted BBK with race pads moreso than when i used sports pads. Its even more noticeable if you brake gently and your window open you can hear the abbrasive sound . IMHO I don't think that makes the TG incompatible with yellow stuff and i would not worry about it +1 that is will lessen with more wear.

James B Posted June 23, 2010 Author Share Posted June 23, 2010 I should have been more specific - I get the noise even when I'm not applying the brakes. Quote Link to comment Share on other sites More sharing options...
Jay Posted June 23, 2010 Share Posted June 23, 2010 I have just ordered this set up......... so I guess only time will tell if this happens to me Quote Link to comment Share on other sites More sharing options...
Jak Posted June 23, 2010 Share Posted June 23, 2010 Happens to mine too - I could understand if it was just when i applied the brakes, but its a bit wierd that it happens when not braking! Quote Link to comment Share on other sites More sharing options...
ikarus Posted June 24, 2010 Share Posted June 24, 2010 It's odd that it happens when not braking. Are you on Brembo's? Quote Link to comment Share on other sites More sharing options...

fakeindian Posted June 24, 2010 Share Posted June 24, 2010 I get this noise to but I have been told that it's something to do with the air getting in the groves so it makes a noise... Apparently it helps with the cooling of the brakes. Don't know how true this is but I hear it all the time. Just got used to it now Quote Link to comment Share on other sites More sharing options...
Jay Posted June 24, 2010 Share Posted June 24, 2010 Ok i fitted these today....... I am at the bedding in stage and yes there is a noise...... but only when I brake..... so am hoping it means they jsut need bedded in Quote Link to comment Share on other sites More sharing options...

SteveW Posted June 25, 2010 Share Posted June 25, 2010 I have the exact same set up and don't get any grinding noises but do get a sort of clicking sound, kind of like a train noise clickety click etc etc - can only hear it with windows down. Its all to do with the air going down the grooves between the pads and disc. I'd suggest you jack the car up and spin the wheels by hand. If the disk is rubbing on the pad in some places and not others, I would say have your runouts checked on all disks, you might need the discs skimming on the car to get them to run true to the hubs. Checking runout is a must when changing brake discs. All the best Steve Quote Link to comment Share on other sites More sharing options...
H5 Posted June 25, 2010 Share Posted June 25, 2010 Check that the metal plate behind the brake disc hasn't been nudged and is catching the disc itself. I have had this and had to bend it back away a bit. Also check there isn't a stone trapped around the caliper or anything. Other than that, if they have been checked with the wheels off, not sure what else it could be apart from pad and disc noise from the slots.

James B Posted December 9, 2010 Author Share Posted December 9, 2010 Know its been a while but I've found out whats causing the noise and its not good for all those having the same problem. It's caused by uneven brake runoff, which is basically that the discs have been put on badly. Now I have to have them skimmed which is gonna cost £150 for the front 2. I've learned a lesson about being cheap and getting mates to help me with them. From now on the car will just be going to Abbey or any other mechanic I can hold accountable for **** ups. Great lesson in buy cheap, buy twice. - or maybe it should be be cheap, pay twice Hope you dont suffer but cant halp but feel you're probably in the same boat as me. For anyone just joining the thread the noise is a ticking sound that present even when brakes not applied. Quote Link to comment Share on other sites More sharing options...
SteveW Posted December 9, 2010 Share Posted December 9, 2010 Brake runoff? never heard that terminology before. Is that another way of saying brake runout? Or something completely different? My EBC bits are still all good, still no problems even after 4 trackdays. Rear disks are getting changed soon though due to a wheel bearing failure that I didn't notice damaging the disk. Probably going to get Tarox rears just to be a bit different but I would happily buy EBC again. Cheers Steve Quote Link to comment Share on other sites More sharing options...
Cragus Posted December 9, 2010 Share Posted December 9, 2010 Mine judder at speed - I am taking them to the Garage in Motherwell when I get back on the road. Quote Link to comment Share on other sites More sharing options...
James B Posted December 9, 2010 Author Share Posted December 9, 2010 Here's the response. The vibration may be caused by the discs being fitted with more than 0.002†runout initially. The only way forward now is to have the discs skimmed on the car. Please read the information about Pro-cut lathes on our website www.ebcbrakes.com So yes it was runout. Being largely clueless its not a term I had heard before. Quote Link to comment Share on other sites More sharing options...
Cragus Posted December 9, 2010 Share Posted December 9, 2010 EBC told me the same thing when I phoned them mate! Its funny how most people who have these rotors are having the same problem. My car has been off the road for a while so I was going to deal with it when the good weather comes in but I might just take it up with EBC sooner.

James B Posted December 9, 2010 Author Share Posted December 9, 2010 If you're near Northampton you should. They gave me a number for somone that skims the discs for them for free. Surprising they should have that relationship with someone if its such a rare occurance?! Only problem is its way too far for me to go so I'm getting Abbey to do it for me. Either way I dont think I'll be getting EBC next time. Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted December 9, 2010 Share Posted December 9, 2010 Everyone I spoke to on here said to avoid EBC rotors can't say I have changed my mind any reading all of this thread... Quote Link to comment Share on other sites More sharing options...
