Tandem Circuit System
If air enters brake system, bleed system effected. Keep fluid level in reservoir above dividing partition while bleeding system.
NOTE:
Do not apply brakes hard until all air is expelled from system. This will prevent the brake pressure differential valve from actuating brake warning switch.
Clean bleed valves, start bleeding with rear brakes first if both systems are being bled. When bleeding rear brakes, release handbrake and turn shoe adjusters to lock brakes. Connect a hose to bleed valve farthest from master cylinder with end submerged in jar containing clean brake fluid. Unscrew bleed valve about 1/2 turn, depress brake pedal, but not to end of stroke, and allow to return slowly. Pause between each pedal stroke and note when bubbles cease from fluid being pumped into jar. Tighten bleed valve when pedal is depressed and repeat procedure with other brake(s).
