Rear brake caliper siezing or dragging?
Qlisters please assist I need to know by tommorrow AM if possible to order the
On the way home from MT Washington and my vacation following my rear caliper
siezed or really just dragged enough to wear away the pads completely on the
passenger side rear. My mechanic said I had a siezed caliper (it was about 4
years since I had the calipers rebuilt so I said ok. I ordered 2 new rotrs

a different one, but I'm wondering (due to the recent thread on the RR caliper
dragging with a stuck MC if thats what I have too. I'll try at least to order
a new MC tommorrow.
On the MC does anyone know if you can just order the larger one from the
wagon(or a later Quattro?) will it fit/work ok?
