Brake Lubrication

[khanh007]

I received my new rotors yesterday, and I plan on changing out the pads at the same time for my 07 SE.

This is going to be my first brake job, so I'm just going over details to ensure a clean and good brake job.

My question is regarding the lubrication of the different brake parts to ensure that there is no squealing afterwards.

I've read different threads from different sources on the internet, but most say to lube the contact point where the brake pads seat on the caliper and on the backing plate of the pads themselves.

I also read that only a certain type of lubrication should be put on the back of the pads since there is a shim that is installed on the OEM pad that may come off due to incorrect lube types.

Other than the pad seat where the brake pad sits on the caliper...and the backside of the brake pad (opposite side from friction material) is there any other part that should be lubricated with brake lubricaiton to prevent squealing?

Any insight appreciated...

Thanks

You should only lube the caliper slides/pins.

You shouldn't lubricate the pads anywhere.

Brake noise is caused by vibration, which shims help to absorb.

Thanks for the heads up.

The TSB for the front brake squeak says that the shims must be replaced along with the worn pads. It also gives instructions on how to install the shim using disc brake grease...

Do you know if the brake shims on the back of the brake pads are included with new pads?

Thanks

Pads and shims come seperate. Shims are reusable. You can use your old shims on your new pads. If you use aftermarket pads the OEM shims may not fit properly.

I don't care what the TSB says, you'll only find me ever lubing caliper slides and brake shoe and backing plate contact points. Excessive heat causes the grease to expand and thin out. It will then bleed out onto other brake componants.

I'd rather use a silicone gasket maker between the shims, pads, and caliper piston(s) to help absorb vibration than any type of grease or other lubricant.

the most important thing is that you clean all the old parts like new. The slides like the other guy calles them, i.e. the stamped metal things that the pads slide in. DO NOT use compressed air! (asbestos!)!! Use brake cleaner spray (to keep the dust wet).
You can use high temp brake grease (and no other kind) on the moving edges of the pads where they touch the slides. Sometimes i put a thin smear on the hollow edge of the piston where it contacts the inner pad.

But im not sure this is really doing much in between brake services ...for the reasons he said too. When you put any kind of grease on the brake parts, in operation it gets mixed with brake dust pretty quickly. Thus negating most of what you want the grease to do. So if you left them dry i suspect you might achieve about the same result. (If the brakes squeak, THEN i'd grease them for sure.)
