Squealing brakes - Toyota Nation Forum : Toyota Car and Truck Forums

dcarter124 · 11-09-2005, 04:55 PM

The brakes on my 96 camry 5sfe squeal like no other. THey have been squealing for a while now, i checked it before and the mechanic said there are no problems, they only squeal because of the semi-metallic pads. I had the brakes checked again yesturday and I basically got the same answer. BOth pads are in good condition and there are no safety concerns according to the mechanic, he explained that that is common for older models of foreign cars.
Is this hapenning to anyone else?
any thought?

spray some DW-40 that should keep the squaling down

wd40?? are u foreal?

My front passenger brakes make noise but it is not a squeak. It has more of a spring sound and only does it on light braking. I have also noticed that that sides pads grip and then it kinda of lets up then grips again, all while having the brake pedal in the same position(still lighting braking). I just had my car in for maintenance and my mechanic is my pads and everything was fine. I would like to know what is going on too. It is very annoying and has been doing this for over a year.

yep, my bros WRX was making this sound too. so he sprayed some and its so much better now. you need to do it couple of times before the sound will go away. if it doesnt....

go to Toyota.

check to make sure your anit-squeal shims are not rusted or damaged, check to make sure the springs are still there, and then slab some extra anti-squeal lube on there

and adding to all that could be a seized caliper bolt that will make it squeal even more

Diehonda · 11-09-2005, 07:08 PM

you could have glazed pads, they look shiny. Or the antisquel shims are ajar. Take a look and put some brake grease on them.

Sometimes with Lifetime pads, the brakes squeal (or make a high pitched sound). If you have lifetime pads, you can take them off, use some sand paper and rub them a little to make them rough again. But, your wear indicator may be going off (time to replace the pads) in which case your pads will squeal no matter HOW HARD YOU PUSH ON THE BRAKES! With lifetime pads and them squealing, if it is just brake dust, you can push on the brakes hard and it won't make a sound. That is how to tell the difference. If you push on the brakes hard and it still squeals, it is the wear indicator. If it goes away when you push the brakes hard, it is just brake dust, don't worry about it.

I know with nissans when ur breaks sweak it means to change out ur breaks is it the same with toyotas perhaps?

fe519 · 11-09-2005, 09:08 PM

usually squeeky brakes is because of the rotors not being "perfectly" smooth around. Ive also noticed that camry hates other kinds of brakes except toyota pads. I had those Kragen "Raybestos" crap on my camry... and squeeked like hell...

normally it's true, but mine squeek sometimes and i have plenty of pad left, just as dcarter stated also. what fe519 says is true, thats why if mine squeek to the point of freakin annoyance, i will be doing what stirfry boys says about ruffin up the pads and even the disc

my pads are the ceramic ones installed at a local good year shop

majorgercko1 · 11-09-2005, 09:16 PM

I read on my owners manual (2002 camry se) that the squeaking noises may be because it needs to be replaced, the breakpads. I think it has some sort of system (my car) that when it suqeaks it means you need new break pads.

Cyorke · 11-09-2005, 10:34 PM

If you are mechanically inclined you should take the front brakes apart and make sure all of the antisqueal shims are in place. There should be two on each pad. Total of four for each side. Then you want to take the pads and scuff them with either sand paper or jsut rub them on a concrete floor. Then when you are ready to put it all together make sure you lube all of the slide pins really good with high temp grease. The last thing you can try is put jsut a very small amount of high temp grease where the brake pads actully sit in the bracket. Where the tabs are that position the pads that is.

how serious are you? because i know that wd-40 removes grease and grease is needed as a lubricant for the brakes

that was my first thought, till a mechanic looked at the pads and told me they are still good

Mike Gerber · 11-10-2005, 12:50 PM

Since dcarter124 has had his brakes inspected by his mechanic twice, we can assume he has plenty of pad thickness left. If that is correct, then this leaves 2 possible causes. The first is if the brakes make noise until they are applied. If this is the case, the noise is usually caused by the pads actually vibrating in the calipers. This sets up a harmonice vibration resulting in noise when the brakes are not being applied. For this, use some disc brake quiet on the backs of the pads. You can use the spray or the gooey stuff spread on the backs. I have had good experience with Permatex Disc Brake Quiet. Take the pads off the front brakes, keeping them oriented to which side of the caliper and which caliper they came off of. You will need to put them back in the same spot. Spray the disc brake quiet on the backs of the pads, or spread the gooey stuff on the backs. Give them 5 or 10 minutes to set up and then reinstall them. The noise should be gone. The stuff you put on the backs keeps the pads from vibrating in the calipers.

If the noise is apparent when the brakes are applied, (second possibility) then you need to try some different pads. I would recommend Raybestos full ceramic pads. I talked to one of their engineers a few years ago. He basically told me that as of November of 2001 the federal government mandated that there shall be no more asbestos used in brake pads. Up until that date they could still use little bits of asbestos. His actual statement to me was something like "Manufactureres have been experimenting with different compounds in order to get the right mix." Up until late 2002 or early 2003, I always used their semi-metalic pads. When I tried them at that time, I too got horrible noises when the brakes were applied. Switching to their full ceramics cured the noises. Toyota OEM pads are another good choice to cure this noise when braking.

YMMV.
