    Brake discs rusting

    Brake discs rusting 10th Sep 17 at 8:17 PM
    Why do brake discs rust?

    I have one disc that is rusting on the edge, as others on here have had similar issues, I thought I would ask if it be avoided.
    I recently put new pads in, cleaned the disc a little with emery paper and a file. But the rust is still a thick ridge.
    As I have alloy wheels, I can see that because the disc has a ridge, the new pads are not touching a small section near the rust, so the rust will be spreading.
    Not sure if it would have been practical to remove the discs, with the pads (Megane 2006), but renewing the pads is making the rust worse.

    I changed the pads about a month ago, and the pads have not yet worn past the ridge of rust. At the moment, the rust is minor. the car has recently past its MOT.

    I think posting that for someone to read who isn't aware of brake disc rust and who could well follow that advice is akin to giving a loaded gun to a 5 year old.

    Under no circumstances ever put any kind of lubricant onto a cars brake discs.
