- Install SST (09709-29017) gauge set on front and rear calipers. Bleed air from system. See BLEEDING BRAKE SYSTEM. Raise master cylinder (front) pressure and read gauge at rear wheel. See PROPORTIONING & BY-PASS VALVE PRESSURE SPECIFICATIONS table.
- Check system at specified pressures. Rear pressure increase should be less than front pressure increase. If rear wheel cylinder pressure is not within specification, replace valve assembly.
