Squeel when driving under 20mph

[skyxliner]

So I tend to drive aggressively from time to time. Mostly just high speeds on the freeway and not heavy accelerating.

Recently while driving, I noticed it started happening when I wash my car and water gets on the brakes. I would only hear the squeals when braking. but after some time, I start to hear the sound driving anytime under 20mph. The sound actually goes away when i brake so I'm not sure if its the brakes or not.

I'll see if i can get a video clip.

any help?



additional info:

- odo: 28500
- brakes: 28500 (still oem haven't changed)
- last time i checked my brake pads at 20k there were still a lot left

- sound only occurs under 20mph and goes away when i accelerate
- occurring definitely on right side and i "think" rear right wheel

- sound begins when driving from a cold start or stopping temporarily
- if i intentionally turn left, the sound is directly because of it
- if i turn right, occasionally the sound will also come up


- sometimes the sound is a constant high pitch squeel
- and a times the sound is eeep eep eeep eeep. but that might be the terrain i'm driving over causing it but it's patternized

so wheel bearings or brakes?

My dad usually does my brakes and i don't have the tools because i'm away from home or else i'd open it up and see how my brake pads are doing.

video is coming!

Sounds like the pads may be dragging a little. The pads depend on normal rotor runout to move freely. If the pads and guides are dirty the pads can get stuck. If your last brake job was done by you, or even if it wasn't, sometimes the pads are made with half a millimeter too much metal, and this can make them stick. (I have taken a file to the metal on brake pads more than once for this reason.)

For the lazy man approach, hose down the calipers with brake cleaner, if you notice a difference, remove the wheels and clean the brakes - remove the bolt, flip the caliper up, pull the pads, and clean everything they touch. Brake grease on the pad contacts, the guides, and the pins ought to do the job, if not, maybe you are missing a shim. The anti-squeal brake goop sold by the packet at the auto parts may help.

thanks for the reply, I talked to a friend of mine.

He suggested it being the wheel bearings going bad.

anyone have experience with wheel bearings going bad?

i have custom rims not stock.

haven't changed my pads yet, i believe i'm alil under 30k right now.

How old r your brake pads? Symptoms sound like they r near to be replaced. Usually this sound is made by the wear indicator. Check the brakes anyway.

A wheel bearing should make noise all the time but changes pitch as you accelerate. If it's a wheel bearing then a light application of brakes can stop the noise. But that should be a grinding growling type of bearing noise. You can try to verify by making turns in an empty parking lot. It should get noisier as you put load on the problem side. You may also have some free play at the hub.

Squeeling brakes AGAIN!

how many km's on your car?
how many km's on the brakes?

It sounds like your pads might be rubbing on the rotor. Does it have a consistent squeel ? or does it like squeel in a pattern? Like its hard to explain but does it squeel , then stop then squeel again in a pattern?

hm from the additional info...
It could be from a warped rotor that is rubbing on the pad as your driving.
or the slider pin on your caliper could be stuck... Happened to my accord and I put it off for a bit. Result, my one pad was worn on an angle, one end was like 80% while the other end was like 10% ..... I lubed the slider pins up with some lithium grease and it went away.

You should take a look at your brakes and pads to see if there is any uneven pad wear, or if you can see if the rotors are warped.

At 30,000 the problem is probably NOT the wheel bearings and this sounds like a common pad problem anyway. Brake noise is actually a phenomenon that involves the pads vibrating in their mounts, a normal condition and why the brake manufacturer designs in the special shims, etc.

Like the other fellow say, check the amount of pad lining left, if they are getting low or marginal (10mm or less) just change them. If the new pads do not come with the brake anti squeal compound ( the blue goop) i'd buy and use it anyway. Also check rotor condition, are they smooth? If not turn or replace. A brake job ought to fix the noise, it is probably NOT a wheel bearing.

Sounds like a wheel bearing to me. My uncles 07 Tahoe made that same noise and we found out that it was a wheel bearing. jack the side in question up and spin the wheel, does it spin freely or can you feel some friction or play in the wheel?

okay guys! took off my wheels and inspected the brake pads. The front were perfect and still had a healthy amount left.

the rear however were horrible. my dad mentioned his suspicions about the rear being worse than the front, and that it usually is the other way around. the inner pad was even worse. it was near metal pretty much. I went to autozone and bought the duralast gold ceramic brake pads ready to replace them and call it a day. BUT, I stumbled upon a tsb for this exact problem.


New Rear Brake Tsb - Tsb Br007-07, 11/7/07

posted by njerald, 11-26-2007. i'm surprise that thread didn't get ANY attention at all. is it just because no1 has checked theirs yet?? my car is 2007 LE Japan made. Seems like these symptoms are exactly what the TSB describes. New Pads for rear brake squeak and/or premature pad wear.


Does anyone have the actual PDF TSB for this? or has anyone went in and done this TSB? Thanks!

[skyxliner]

so are you saying it's not the TSB?
it was confirmed the rear right brake was squeeling, and that side had the worst brake pad left.


this article supports TSB
can my back brakes be done already




Changing Brakes '07 Camry
after this one i understand what u mean by the EBD, but either way, toyota should replace it for me right?

[CamrySExxx]

i totally forgot about that tsb!
Our camry actually had the same squeeling problem when you reversed... but we never did anything about it and it went away. and just to back up djkor, the rears do wear a bit faster on the newer cars because they are used a bit more to avoid the car's front nose from dipping down on hard braking.
