I installed full SC rotor system on my RAF. The rotor brake is ineffectual. The rotor spins even in a light breeze while pulling VERY hard on the brake handle. Once, I pulled so hard the ferrule broke. Initially, the brake shoe only made contact on the outer edge. I sanded the brake shoe to match the brake shoe/PR gear application angle on a flat bed belt sander and now have a more uniform contact surface on the whole shoe. This helped very little. I also roughened the contact surface on the PR ring gear. Nothing has helped so far. Looking for ideas, perhaps refabricating the brake handle, or anything else.
