rusty rotors

[Fred Munro]

Yup, I solved this problem on my '86 5ktq and '91 200q.

The rear brakes aren't working hard enough to clear the rust from the rotor
surface. This is what I did to solve the problem:

Every fall:

1. Make sure the proportioning valve is free and working properly.
2. Remove the rear calipers and pads. Clean and lube the pad contact points
on the caliper carrier.
3. Remove the caliper guide pins. Clean and lube.
4. Pop up the e-brake cams. Clean and lube the shafts. Make sure the e-brake
cables are free.
5. Put it all back together. Use the e-brake regularly to keep the rear
brakes adjusted.

This ritual is a bit of work, but kept the rear brakes working well enough
to keep the rotors clean.

You can also use a more aggressive pad.

In search of advice to end the rusty rotor ritual. Each winter up here in
the rust belt the rear rotors on both my cars rust up and each spring its
new rotor time. I've tried some different combinations of rotor/pad
manufacturers each time and the problem persists.Has anyone else that has
had this experience found a solution?
