    Too-Warm Rear Disc...

    I prob oughta put this in Tires and Brakes, but anyway. I think I know the answer to this (rebuild the caliper...), but I guess I'm kinda wondering what's not out of the question to just live with.

    I put new EBC pads in the rear caliper when I was putting the wheel back on with a new tire a week or so ago. One of the old pads was worn more than the other, which I knew from checking a while back. Now the disc is overly warm after a ride, and it wasn't before (that I remember...). I can grab it but just for a second; so it's not just blazing, but I don't like it. I can grab both of the fronts and hold them.

    The rear wheel spins as freely as I'd expect, both ways, like it did before.

    Yup, rebuild the calipers. Use OEM seals, if at all possible. And replace the brake lines if you still have the originals.

      Onto the list of other stuff I'd rather not, but have to get to eventually I guess...

        One pad was worn more than the other because its piston was stuck and could not retract properly. Might be a simple case of cleaning the piston, might be a worn-out seal, but a fresh rebuild will take care of both of them.

        "Rather not do"??? Consider that overheated brakes are not much more effective than NO brakes.
        Still want to put off the job?
        If you're not living on the edge, you're taking up too much space.
