    Default Quieting brake pads, an unusual approach

    Hi,

    When I replaced by pads and rotors the other weekend, I had a of a time getting the calipers off the rotor, which did have a substantial lip. I had to push the pistons in while on the car, to get enough clearance.

    Once off, I realized why - the pads had been glued to the caliper and the piston with silicone adhesive! Granted, the brakes never squealed but isn't this a bit extreme?

    Perhaps this is a common technique; anyone else use it?

    Regards,
    Adnan

    Default Most of the antisqueal compounds when dry are just like silicone adhesive, they come

    They usually come in a blue or an orangish color... Are you sure it wasn't the antisqueal compound?

    Default It was orange, so you're probably right (as usual)! (nt)

    Default I love that stuff...of course Martin has no clue how to use it.

    Doesn't matter what pads he installs, they still squeal....

    Default You did tell him not to put it on the side that goes against the rotor?

    Default I think he's still trying to figure out which side of ...

    The best (and cleanest) anto squeal compund to use are "shims". Aluminium/rubber compound in a sheet that you cu tto fit where the pad meets the caliper. Adhesive on 1 side to fits in place. Pick them up form you brake expert/shop.
