BRAKES!! Please Help!

[Barney392]

Those are Toyota brakes, famously noisy. Best of luck.

2 years on TeraFlex and never a peep! I am not a light braker though. I usually lean on them, all the time. Light braking will cause any pad to become noisy over time as the pads will develop a glaze.

Just my $.02

EBC is good, Akebono, Hawk, AC Delco Specialty/Fleet, I'm sure there are others.

Gotta ask though, do you drive with both feet? Using the left for the brake? or does anyone else who drives it do that? Many people who do will ride the brake pedal slightly, which causes the brakes to glaze, which will cause squealing. Never drive with 2 feet unless you have 3 pedals.

Been thinking about this problem. There is also brake grease. A little goes on the back side of the pads on the piston(s) or caliper "ears" that contact the back of the pad. This is supposed to damper the vibration causing the noise. Additional info.

Personally I prefer the "brake glue" for the back pads. As for the "ears" it all start with file down because I never in my life got a properly fitting brake pad "ears" that would slide freely.

Get up to about 50 mph and hard brake to a complete stop. Do that three times to remove the glaze. It works.

Good bedding process, but not to a complete stop. To like 5 MPH, then drive for a minute or two between each time. The idea is to not have too much bake pad material transfer in one spot if you completely stop, as the pads will be clamping to a red hot rotor. After the last braking event, you want to drive for several minutes, so that the rotors and pads can cool. If you get stuck at a light or something while they are still very hot, take your foot off the pedal and use the parking brake, or put it in park or neutral. With brand new rotors and pads, you will want to do this 4-5 times.

Yea, I even opened a case with Powerstop and they sent new pads. Immediately did the bedding process they call for. Next day on the way to work SQUEAK!!!!!... like WTF. and again. Lubed up the pins, the contact points on the caliper ... And ill tell yea.. 2-3 hard stops first thing in the morning and the squeak is gone for the rest of the drive.

I have power stop brake and rotors. Mine squeek/pulse for the first 5-10 mins (light brake, heavy brake makes no noise) and then once warmed up are fine. I too have tried everything. Ill be pulling the trigger on the teraflex front brake kit at the end of this month. I'm just fing done with this noise.

did you do the full break in procedure? i have 20K miles on my power stop brakes without any squeaking. the with the factory brakes i did get squeaking when love days in hot hot weather wheeling or after mud/water crossing. easy way to fix is heavy grit sand paper on the pads and rotors. Changes the wear pattern just a little to help with the glazing the rotors

Yes, Its something i always do. the full procedure in cluding the cool down drive aswell. This is my 5th set of powerstop rotors and brakes on various cars and never had an issue.

wonder if it had bad heat treating on a run of rotors.

Were the rotors and pad surfaces thoroughly cleaned with brake cleaner spray prior to mounting, then after in the event that any grease or oil was transferred form hands or gloves?

the first time yes, the 2nd, well no

You can pull the wheels off and spray them down really well. Then do another bedding process. If you didn’t pull the caliper pins, clean, re-grease, then burp the seals, it would be a good time to do that too.

Most people skip the caliper pins, even some shops. Make sure you use high quality synthetic brake grease.

Yep, i always wipe down and reapply syn lube to the pins. What is Burp the seals?

Push the pins in and use a pick to lift the edge of the seal. It allows air, or any excess grease to escape, so that they will move freely.

Thank you for all of the responses.
Responses to questions asked:

I did do proper bedding. When they start squealing I can bed them again. And it stops.

I have replaced pads 3 times. Rotors twice. Calipers twice. All to rule out possible bad components, contaminate parts, etc. Zero change.

I do not drive with 2 feet. Just one.

What confuses me is why the noise goes away after parking for a while. Like overnight. The noise is gone in the morning. Then it starts once I stop and go quite a few times and doesn’t go away unless it is parked for hours or I re bed the brakes.

Confused.
