The last brake pads I bought came with a tube of brake lube. I had never used this before, so I did not use it this time. Now my brakes squeal even though the pads are brand new. What is that stuff supposed to do, and how do you use it on the brakes?

It's weird that no matter how long you've been into cars, there are always little questions like this that pop up! Thanks.

 

It's anti-squeal liquid actually. Good thing, as it looks like you could use some.

 

LOL. Good call. How do you apply it? I assume you don't apply it directly to the material on the pads, correct?

 

you put it on the back of the pad, where the pad meets the caliper.

 

That's what I thought, but how does that prevent squeal? Isn't the noise coming from the pad to rotor contact?

 

No, brake squeal is caused by the rear of the pad rubbing against the caliper inserts.

Just apply sensibly to each pad's backside, replace the pads, and your good to go.

 

Brake pad treatment usually isnt labeled as a lubricant. The stuff you put on the back of pads is usually a tacky substance, thickens as it dries. If what you have feels more like a lubricant such as grease, then what it is for is the caliper slide bolts. The bolts that the caliper actually floats on need to be lubricated. these bolts not being lubricated properly will cause brakes to squeak. Regardless of what you have, lubricate these bolts regardless, but do not use bearing grease. Use dielectric grease or what is labeled as caliper slide grease.

 

Nor is it labeled as "treatment". Caliper-pin grease usually only comes with replacement pins, guides, or new calipers. Anti-Squeal is the #1 included item. But yes, like 5.0 said, lube for the pin guides does sometimes come with pads.

I guess the next question is, what does it say on the container 12sec?

 

Haha. Wouldn't know. I threw it away with my old pads because I knew that if I ended up needing it, I can buy some somewhere. It came in a little plastic tube, and it appeared to be a clear color.

 

Well go back to the store and get some anti-squeal.
