lineaway Posted June 15, 2016 Report Share Posted June 15, 2016 Do you still have the disc guard on with the spacers? If not the bolts shoulder can be too long. Quote Link to comment Share on other sites More sharing options...

Just bear in mind that the top mounting bolt also seals the one half of the caliper. If you pump the brakes with the bolt removed, it will leak.
