Master cylinder / booster mount
Quote:
This post will show how I designed a bracket for the master cylinder & booster. I wanted the actual mounting bracket to be welded permanently to the chassis, yet have a method for dropping the actual pedal assembly out for ease of assembly as well as maintenance of the unit in the future. It might be hard to make sense of it in the pictures, but I'll try to describe it below if possible. The first picture shows the overall design of the bracket, but doesn't show what comes apart for removing the pedal pivot very good. It does however show the pedal pivot shaft bolt (the one with the grease zerk in the head) The second picture helps show things a bit better. You will notice the pedal pivot shaft is actually split into two halves. The one half that is tack welded to the actual bracket extends through a drilled hole in the inner boxing plate of the frame and is welded both on the inside of the frame and on the outside of the frame rail where it's welded flush. The other half of the pivot shaft (the one with the cardboard mockup pedal and the arm that attaches to the heim & rod going back to the master cylinder) is removable. To remove the pedal assembly shaft you unbolt the shaft pivot bolt (The one with the grease zerk) and unbolt the plate on the opposite end of the shaft (the diamond shaped one with two holes in it) which is actually attached to a shaft machined to the i.d. of the outer shaft. Once unbolted, the inner shaft slides out and the pedal portion of the shaft will drop free. Note: The machined inner shaft has a machined spiral groove and is drilled to allow the grease from the zerk to lube the entire shaft length. Here the complete assembly is tacked into the frame rail. The diamond plate bolts to the outer frame rail with two bolts to "lock" the inner shaft into position (along with the center pivot bolt with the zerk) View from the other side
