Does anyone have diagrams and/or a parts list showing the brake pedal through the master cylinder? The person I got my wagon from eliminated the pivot. The brakes work, but braking is soft and the pushrod is at an obvious angle. Trying to figure out what's there, not there and what I might need to fix it and hopefully improve braking. All OEM brakes and it doesn't have a proportioning valve. '78/'79 wagon and race only. I've already replaced the manual M/C, rear brake assemblies, brake hoses and thoroughly bled them several times.
