Hello all,

I just changed my rear brake pads due to squeaky brakes.

Rear passenger side rear level was more than driver side rear. However, driver side rear, the caliper does not slide at all... Rear passenger side didn't slide smoothly but it did slide. I put some brake grease on the sliding bolt and it was much better.

On the driver side rear, I took off both sliding bolts and greased them and inserted/reinserted a couple times. I noticed that as I am inserting the sliding bolt into the caliper bracket, it feels as if it is pushing the bolt back out, like the air has no where to go so it's acting like a piston. I was able to screw them back in place and tried to move the caliper and it still doesn't slide freely.

So I'm thinking I need a new caliper bracket. I'm going to try to clean out the hole where the sliding bolt goes in tomorrow and also get new sliding bolts.

What do you guys think?

 

There's nothing to wear out on the brackets. Make sure you don't have too much grease, and I use Permatex graphite anti-sieze in a very thin layer. Also make sure the rubber boots aren't binding, and that the stainless steel clips aren't misshaped. Finally, as you stated, the holes should be clean and free of corrosion, as well as the pins.

 

Thanks for the tip dcains. Cleaned it out earlier today and bought new sliding bolts along with the anti seize and it works great now

 

Happy to help, and I'm glad you got it repaired properly. Good for you.

 

Actually this is what is supposed to be on the pins

 

You can use either, but the graphite is far more heat-resistant than the silicone, and you can also use the graphite in a bunch of other places on the car.

 

Im pretty sure you use silicone grease on the sliding pins because anything else will cause the rubber bit at the end of the sliding pins to swell up. Which makes the pins difficult to slide in/out.
