EBC Yellowstuff LOUD (Help)

Brakes usually squill because over time, the pad material glazes the rotor surfaces. The best way to avoid this situation is to install new OEM rotors and new pads. A less expensive alternative is to resurface the rotors along with new pads.
I have had the same happen to me several times with different cars. Kind of embarrassing.

 

The rotors need to be resurfaced or replaced. If that was already done, there is probably no way around changing to different pads. The brakes have stiff calipers and are very sensitive to squeal. OEM pads have a groove cut in them to keep them quiet. Most aftermarket pads do not. Girodisc pads and StopTech street performance pads are mostly quiet among aftermarket pads.

 

Proper resurfacing removes so little material if in fact they are as you describe there is no reason not to resurface. It is like anything else, there are a lot of people out there that do a terrible job of it and a few good ones. Putting new pads on an old surface is in most cases a bad idea. I resurface them every time and have done several cars 4 times and are still not down to min thickness.

 

I've had these, it won't go away u need to change them out unfortunately

 

I swapped from OEM to the EBC Yellowstuffs and went through the same squealing issue. Your brakes aren't properly bedded. The yellowstuffs are a high temp pad and really require a lot of heat, much more than oem to properly bed them and get a solid transfer layer on the rotors.

2 track days and the high frequency squealing at low speeds went away and now it makes a dull metal grinding sound at stops, which is much less annoying.

If the sound is a major problem, swap back to OEM, but know that the life on those pads is not great.

 

It is likely that that pads are still not fully bed in especially since the rotors were not resurfaced. This means that the pads must first scrape away the old pad material that is on the rotors and then embed it's own pad material. In the process however it can be difficult to get a nice even transfer layer on the rotors due to the inconsistencies on the face left from the original pads, this can and will lead to brake squeal.

With all that said the yellowstuff pads are a more aggressive compound and based on what we've seen from our customers that have tried them you're certainly fighting an uphill battle and may never actually get them to quiet up.

We do offer what we call our 'Magic Pads' for the 360/430 which have been an extremely popular compound with this crowd specifically because of their low dust and no noise properties. They are by no means a race compound but if you don't plan on taking the car to the race track they will do everything else you ask of them.

 

They are track pads, not street pads. They work best when up to temp.

 

Nice chat its all bull**** they will never "bed in" whatever you do

 

Get rid of them ASAP before you embarrass yourself and your supplier makes himself look foolish even more

 

I think if you can get your rotors turned, you'd likely be in better shape - Brian is right (of course).

Just based on my own experience, there is something about how a pad interacts with the rotor, or the deposits that it leaves, that makes certain pad materials incompatible with (others or) a dirty/used rotor. That being said, two additional thoughts.

-EBC yellow stuff is marketed as a track-focused pad, isnt it? Pads with a higher temp range usually get noisy and dirty. My carbotech XP pads sometimes are silent, and sometimes howl like dogs. There are little tricks of course (water and a stop to put your face through your steering wheel), but that doesn't sound helpful here. Switching back to the street compound should quiet brakes down.

-Second - proper bedding is pretty important. And.. bedding them usually is done so hot that smoke is pouring from the wells. Like a normal person would think there was something wrong with your car, and give you a really wonky look (that's how I know I've got em good). Not just around and warm from street or highway driving.

I also think its interesting that people go to higher temp pads, without the need... its not worth the trade off unless you need it.

edit - one more thought. I've found it helpful or proper to thoroughly clean out the piston area and put that copper grease on the back of the pads, permatex or whatever.

 

I have EBC pads ... but, I got the Red Stuff pads for street use. Your yellow stuff are not correct for the street use and it is surprising they squeal. My red stuff squealed for a short time but after following the instruction from EBC on their recommended procedure for beddding in the pads, the noise has gone away.

I expect that if I had resurfaced the rotors, I may have not experienced the squealing, but that said, they are fine now.

Unless you do a lot of tracking, I would take the yellow stuff out and replace with red stuff.

Yup, they will dust up very quickly and if not washed off, it will create a bond with the clear coat on the wheels, eroding the coating.

The squeal isn't going to go away with these pads.

 

Just driving around isn't going to have a good chance of resolution. Taking the rotors off and getting them resurfaced is absolutely trivial. So is properly bedding the pads.

 

My EBC Redstuff was very noisy as well. Didn't have more paitience than 50 miles driving before I made the bedding in by getting them very hot. Now the noise has gone. But if you are not comfortable driving the car hard it could be impossible to make the bedding in... In my case we were taking about half an hour driving 'track-style'

 

What I don't get, is why a performance shop would put those things on, without a proper resurfacing. As Rifledriver said, it removes next to no material if done properly.

The Yellowstuff pads are not street pads. They are track pads that works in a setup where the car is driven to and from the track where the noise does not matter. If you really want EBC, get Redstuff. Yellowstuff will always be noisy, unless you drive like you stole your car or ran the MM, EVERYWHERE! And as mentioned above, the Redstuff can make noise as well.

All that being said, I've tried all the colours, and I think EBC is the most overrated pad out there. You get what you pay for. Pagid makes really nice pads though.
