Models Without ABS

  1. Ensure all tires are properly inflated, and all brakes are in good condition and brake lining is within specification. If all conditions are satisfactory, go to next step. If all conditions are not satisfactory, correct as necessary and go to next step.
  2. Check height-sensing proportioning valve adjustment. See HEIGHT-SENSING PROPORTIONING VALVE  under ADJUSTMENTS. Once height-sensing proportioning valve is properly adjusted, go to next step.
  3. Remove valve adjustment nut at valve actuator. See Figure . Remove valve actuator from lever on height-sensing proportioning valve. Height-sensing proportioning valve is located on outside of driver's side frame rail, in front of rear axle.
  4. Disconnect junction block-to-height-sensing proportioning valve brakeline from front of height-sensing proportioning valve for appropriate rear brake being tested. Disconnect brakeline for one brake from rear of height-sensing proportioning valve. Install Pressure Test Fitting (6833) between brakelines and height-sensing proportioning valve. See Fig 1 .
  5. Install Pressure Gauges (C-4007-A) on each pressure test fitting, and bleed air from pressure gauges. See Fig 1 . Bleed air from brakeline being tested at rear wheel cylinder.
  6. Have an assistant hold brake pedal down until inlet pressure at height-sensing proportioning valve is 1000 psi (70 kg/cm2 ) and note outlet pressure on height-sensing proportioning valve. Outlet pressure should be 250-350 psi (18-25 kg/cm2 ). Replace height-sensing proportioning valve if outlet pressure is not within specification. If outlet pressure is within specification, go to next step.
  7. Remove test equipment. Reinstall brakelines on height-sensing proportioning valve. Tighten brakeline nuts to specification. See TORQUE SPECIFICATIONS  table. Repeat test procedure on remaining rear brake hydraulic circuit. Replace height-sensing proportioning valve if outlet pressure is not within specification.
  8. Remove test equipment. Reinstall brakelines on height-sensing proportioning valve. Reinstall valve actuator on lever at height-sensing proportioning valve. Adjust height-sensing proportioning valve. See HEIGHT-SENSING PROPORTIONING VALVE  under ADJUSTMENTS. Bleed brake system. See BLEEDING BRAKE SYSTEM  .
