I have a '95 contour. The passenger side rear brake drum started locking up with even a gentle depression of the brake pedal. The brakes were working fine earlier today...I've had noises coming from the front drivers side wheel (unrelated to this brake issue) so I had that particular caliper off today trying to find the source of the noise (which turned out to be the drive shaft). After finding the source of the noise, I put the caliper and wheel back on, and I took it for a short drive. Thats when this business with the rear passenger side wheel started happening. I wonder if in my messing around with the front caliper I may have collapsed the flexible portion of the brake line on the front caliper. If so, would this cause the rear passenger wheel to lock up when depressing the brake pedal?? (The front drivers side brake caliper appears to be working normally).
P.S. its probably worth mentioning we had snow recently and the streets are still packed with snow. So, when I say the rear wheel is locking up, its doing so on a somewhat slick surface.
