Greetz All,
I recently replaced all 4 rotors on my '86 GTI. After about a week of driving, I noticed that on both rear rotors, there was about a half inch band of surface rust on the inner diameter of the disc, and the machining marks had not gone away like they had in the front. This rust is only on the outside of the disc.
I started poking around and discovered the regulator was seized. So I replaced it along with most of the brake lines. (always a fun job)
So now after a couple more weeks of driving (120 miles a day to work) the rust is still there. I thumbed through the Bentley and found a diagram of the pressure regulator and noticed it only showed the single large spring from the axle to the regulator. Mine has a second smaller spring connected from the bottom of the lever to the large spring itself. An image of the second spring location can be seen here,
Thanks for any info.
