Today I continued working on the brakes. I started by up drilling the 5/16 inch holes in the brackets for the master cylinder and temporarily mounted the cylinder so I could drill the hole in the floor for the inboard bracket. Next I drilled the pilot holes for the rivets in the floor for the inboard bracket. I trimmed the plastic film on the floor from around the mounting points in preparation for riveting. Once the floor was prepared I riveted the inboard bracket into place. With the bracket mounted I cleco’d the inboard bracket in place.
