Dual Disc Conversion r90/6
Posted: Thu Jun 02, 2022 11:26 am
I am converting my 75 90/6 to dual discs. Put everything together last night, with the left caliper going in nicely. When it came to the right side, the hole in the caliper would not line up with the holes in the slider. My first inclination is to shim behind the disc on the right side. Alternatively I could slightly increase the axle spacer, but that may throw off the left side.
I measured the space between the outside face of the disc, and the top "arm" on the slider at the closet point. Left side is 1.3mm and the right is 2.25mm. To shim out the right side will take one or possibly two washers, or bmw part # 34111232417.
All advice would be appreciated.
thank you
