To check for this condition, measure the disc at 12 points with a micrometer at a radius approximately one inch from edge of disc. If thic...

If the rear (secondary) brake system fails, initial brake pedal movement will cause the unrestricted secondary piston to bottom in the master cylinder bore. Primary piston movement will displace hydraulic fluid in the primary section of the master cylinder to actuate the front brake system.
If the front (primary) brake system fails,...
