Horrible brake squealing

I am experiencing horrible brake squealing, when slight pressure is applied to my brake pedal. My brake pads and shoes are fine. Fronts were changed out around a year ago, and the rears at that time had around 80% meat left. I have visually inspected them both recently, and there is plenty of meat left. It's embarasing rollin up to a light, squealin like a pig. It happens when slight pressure is applied to the pedal, when you apply heavy pressure, it's gone. Anyone else squeelin like a pig while braking? What is the fix for this? It's a 2004 PreRunner D-Cab.

 

Brake Glazing maybe?? Try some brake cleaner and see what it does. I'm sure there will be more ideas.

 

Mine did that when my pads went bad. I would have a mechanic look at it

 

98tacoma is right.,
add to that Sand the pads with sand paper. 80 to 100 grit, does nto realy matter.
you just want to ruff them up a bit.

Also what pads do yo u have? are they OEM or a Racing pad?
If they are non oem then you may have a pad the needs more heat to work.

my Race pads squeak when cold and when to light of pressure is applied.
To fix i brake later and harder....

But normal pads my have over heated a bit, try what you have seen.
Also clean the mounting points of the pads, hardware, and caliper and lube the sliders.

Our brakes need to be check and adjusted ever 5k with tire roation or they will wearout sooner than needed.

I get between 60K and 80K on front disc pads when doing this.
and never replace rear shoes. I just adjust and clean...

 

I'll vouche for the disc brake quiet....

I remember on my 96 - the pads had a steal shim thing on the inside of the pad. When I replaced my pads, I took these shims off the old pads and put them on the new pads.....

Do you know if you have these shims on the new pads?

If not.... like 98tacoma27 had already mentioned, applying *disc brake quiet* material on the inside of the pads. You can also get the stuff in a spray can (that's what I use).

 

I had the same thing happen to me, and when I had them inspected it was just a build up of brake dust. But I just resently changed my pads and now there silent as can be.
I would try what 98T has sugested and see if it helps.

 

So this quieting material actually goes on the back side of the pad, correct? Not the side that would come in contact with the rotor obviously........

 

are the toyota pads? because mine were doing that a few weeks ago and my local shop toldme that any other brake pad on a tacoma would squeeeaal.....my sounded terrible. cost me around 50 bucks for the pads

 

Yes

Comes in contact with the piston - NOT the rotor.

 

With the large picture above; showing how to install it this statement scares me...

 

Why is that?

 

Yeah, why IS that? I don't get it.

 

you might want to check to see if you have the backing plates on the pads. some people replace their pads with aftermarket and throw away their backing plates. they will help the squeal cause of less vibration. but i think your only supposed to use them with factory pads.

 

Can anyone confirm if you ONLY use the backing plates with Toyota factory brake pads, and NOT use them with aftermarket brake pads??? I need to seriously get rid of this embarrasing squeal!

 

Does the aftermarket pads come with backing plates?

If the aftermarket pads already have backing plates, then DO NOT use another set of backing plates. Don't stack backing plates.

You could use the original backing plates if you can integrate them to the aftermarket pads. When doing my 96 (it's been a long time), I used the original backing plates on my new pads. The pads I put in were factory replacements.

 

My aftermarket pads did not come with the plates, but I installed the plates from the originals onto the the new pads. Now, if I put some of that anti squeal compound on, will it go sandwiched in between the pad and backing plate, or will it go on the back of the backing plate? I just want to be done with this issue...............

 

Good question...
Technically, since you have the plates - you don't need the anti-squeel compound. They both do the same thing.

But it certainly won't hurt anything to apply anti-squeel if you want. I'm not certain about 'where' to put the compound, but if It were me...I'd put it on the outside of the plate (directly in contact with piston). That way, the plate can still do its job as intended without the compound being in the way (did that make sense)?

 

Yes, thanks!
