My wife has a 1986 Jetta GLI with rear disc brakes. I replaced the rear calipers a couple of years ago, the parking brake cables last winter, and I just installed new brake pads.
Everything works fine till the car sits overnight. Then the rear brakes "stick" making a terrible howling noise and making it difficult to pull away in the morning. Once we drive down the road a few hundred feet or so, the pads loosen up, and everything works great again. But just getting up our steep gravel driveway with sticking brakes is difficult.
I've experienced problems like this in the past, but it was during freezing weather with damaged parking brake cables. Our cables are like new, and the weather is well above freezing.
I've adjusted the parking brake a couple of times, but it has no effect on the sticking problem.
I don't see any kind of "spreader spring" to push the pads apart when they are released, on the car, or in the Bentley manual.
The brakes were sticking before I changed the pads too, but it was more pronounced in reverse than going forward. Now it's about the same either direction.
Any ideas what could be causing our sticking brake problem, and what I can do to solve it?
Thanks,
Anthony
