My front brakes has been squealing for the last 2 weeks, so I decided to change my brake pads today. Everything went fine and the squealing was gone for about 90 miles. The squealing came back
Could it be because I need new rotors?

 

yeah, if your rotors are warped, they can be causing the squealing, you don't need new ones, you can just have them turned for considerably less. but as always, the best thing to do is upgrade! stoptech stage 2 brake package! order one today!

 

Your rotors might have some pits in them or something... I don't think I'd bother having them turned (especially if they're warped). Just go with some slotted replacements or something.

 

That's a quote from a Stoptech employee who works in the industry with brakes.

Rotors don't get warped, in all my years of racing and dozens of cars I have never, ever seen a warped rotor. Ever. I've seen a lot of cracked rotors, a lot of crushed internal vanes, a lot of "bowed" rotors from overheating, but never a "warped" rotor that grinding down a rotor will somehow fix. It's just another one of those "fixes" dealerships have somehow made the public believe is the right way to do things, and is comparable to having a slight ticking noise that you don't know what it is in your engine, and they replace the whole engine and call it done.

I've seen rotors with metal pad deposits on the rotor that will cause a thickness variance in the rotor, but you can visually see the material on the rotor if you know what you're looking for.

Obviously, grinding a rotor down will get rid of that pad material, but it will also lower the overall heat capacity of a brake rotor by a considerable amount.

If you just got new pads, bed-in the brake system properly VIA that link up above, if the problem still happens, check to make sure the backing plates on the pads are attatched correctly, and make sure the wear-indicators on the pads isn't bent or misshapen in any way

 

Saved me some time...thanks.

The only thing I would throw out there is "what pads did you install?"

Some pads need a good bed-in to run quiet and some padswill always be noisy. Without knowing what pads are installed its hard to say exactly what is causing the noise.

 

I installed some Axxix Deluxe brake pads. I did the brake bed using the directions from your (stoptech) site. Could there be something wrong with the pads?
Thanks

 

I try and help, but sometimes I just feel like throwing my hands up, I'm about to turn into one of those "search monkeys"

we should make it a requirement that before you post a new topic, you have to have made at least 5 attempts at a site search with the keywords that are used in your post you are about to make.

BTW, Rice, I had those same pads on my car and never noticed any different noise issues, they had great initial bite and excellent fade resistance when I took it auto-crossing on high-speed, long runs more laid out like a road-course, and the only abnormal noise I noticed compared to stock was when I was slowing down to a stop lightly applying the brake, at slow speeds it made more noise than stock pads, but nothing out of the ordinary

How about a video of the noise? Someone else posted a video when they were having an odd noise and we were able to pin-point the problem immediately.

 

I have the same exact pads and the same exact problem. Exactly what Octocan explained. When I apply the break to stop at a stoplight it squeals really loud but when you hit about under 20 mph it goes away. I don't know what's wrong but it is loud.

 

Did you get it fixed yet? I may have to contact Axxis if this problem persists.

 

i just learned to suck it up, i have axxis ultimates and powerslot rotors, i squeal everywhere i go, but i stop on a whim. and in conjunction with my radar detector, i have avoided many a speeding ticket. i say the squeal is well worth the annoyance!

 

I haven't gotten it fixed yet since I only had the pads for about a week now. I noticed that it squeals like crazy when the pads heat up.

 

I have brake squealing issues too, but mine are the opposite. If I break hard, there aren't any noises, but when I break gently, my brakes squeal really loud. I didn't have this problem until recently. I had about 5k miles before the squealing noises began. I have Brembo slotted stock rotor replacements and Endless brake pads (don't recall which one). I'd splurge and get the Endless Rotors if it can solve my squealing issue when braking gently. Also, I swear it's only coming from the driver side, which is why i think something may be wrong.

My friend told me it's common with performance pads, but I just wanted to add my situation just in case it's not. I've kinda grown used to it, but it's still loud and a little annoying.

I also followed the proper break in procedures for the pads and rotors. I did it late at night on the freeway and luckily didn't get into an accident or get a ticket.

 

Squealing with light pedal pressure is a common issue with performance pads. Some pads will alaways squeal and other will go away with a good bed in procedure and some time for the pads material interface to build up. When in doubt, do another bed in cycle of 10 stops, 60-10MPH to build the brake pad transfer layer.

 

I shall do the procedure again then.

 

just remember NOT to come to a complete stop when the brakes are hot, what I do whenever I know my brakes are hot (like after a race or spirited driving or hill descent) is slow to the point I am ALMOST stopped and slowly pull the E-brake to stop that last bit and don't touch the brakes, the E-brakes are connected to a drum and their temperatures at the hub are usually a solid 200C lower than the rotor face after heavy use of braking, so that should be perfectly fine

 

I had the same problem. Just go to your local parts store and ask for anti-cease or some sort of brake grease. Then ask them how to apply them to your caliper. Your squeaking will be gone after you apply the grease.
