brake caliper freeze? 120-130

posted by  someone claiming to be volvolious on  Sat Jul 2 05:34 CST 2005 [RELATED]


Recently I've had a problem with a scraping type sound as I turn hard left. The sound originates from the right front wheel. The sounds is periodic in frequency... as in when turning it only "scrapes" once per revolution. I took off the wheel yesterday to have a look around but I could not visibly see any points where metal had been freshly rubbed.

I was surprised to find however that the disc and wheel-hub assembly was not turning very freely at all. It seemed very much like the brake-pads were rubbing the brake disc lightly. There did not seem to be any bad sounds coming from the bearings within the hub, but I'm no expert when it comes to knowing what to look for.

Somebody told me that if my brake lines are very old, sometimes they can get to a point where they will not let pressure back up when returnng fluid from the caliper piston. This then causes the brake-rubbing symptom I'm having. Does this seem like an accurate guess on the problem? I'm hoping that it's not the actual piston that is doing the freezing. Should my first fix attempt be to try replacing the brake lines?

Thanks for your input and interest.
