Squealing Brakes Big Time

I purchased a EBC 320 rotor and new EBC brake pads, front and rear (actually I asked for new brake pads and this is what they sent). From the first roll of the wheels and the first oull on the front brake lever the brakes squealed. The information said it would take awhile to stop squealing but it has been 3+ weeks and the front and rear squeal VERY BAD.

I tried some stop squeal on the back of the front pads and it did not help. I pulled them off again and reapplied the stop squeal with no difference. I broke the pads in while commuting in downtown traffic less than 35 mph.

What to do? any suggestion(s) will be appreciated. Thanks.

Thumbs up

Possibly a glaze has formed on your pads or rotor. Did you clean the rotors with brake cleaner before installing the pads ? If not try taking the pads out and clean rotors with brake cleaner and lightly use steal wool to clean. Rough up pads with emery cloth to remove the glaze on them. Try again and see if it helps , remember to clean off all steal wool shreds. Good luck !

This kind of brake squeal p's me off more than politicians and I've found that it generally can't be simply fixed. Although I've never had the problem on bikes, I've pitched auto/truck pads after a couple of hundred miles and replaced them just because of the squeal.

'Bout the only thing I can offer other than replacement is to bevel the leading edge(which would be toward the rear of the bike) and I've only read/heard about that. Assuming the mechanicals are ok - i.e. the pins, etc aren't worn and letting the caliper move around.....

Good luck.

Did you buy new parts or old? Are your rotors glazed/really shiny? Try replacing the pads first. If your rotors are glazed, nothing short of replacing them will stop the noise. I'd try new pads first.

The front EBC 320 rotor and pads are new. The rear EBC pads are new and the rotor is stock. Cleaned the rear rotor with a 3M pad and brake cleaner. Lightly scuffed the front rotor with the 3M pad and used brake cleaner.

I can make the brakes squeal by pushing the motorcycle.

Help my neighbors are closing in for the kill. At least everyone knows I am attempting to stop at stop signs and signals.

Just replace them. Not that many $$'s and my bet is that you'll wind up doing it anyway.

edit - Second thought - if you still have your old pads and they aren't totally worn out, put them back on and see what happens. If they squeal, then you've got a different set of issues. If they don't, then you've identified the new pads as the bad guys.

TOTALLY worn out almost scary.
