7. Two technicians are required for the following steps. Technician #1 should be located at
the caliper. Technician #2 should be sitting in the vehicle to pump the brakes.
8. Have Technician #2 slowly press and release the brake pedal 3 times. At the end of the
3 depression, the pedal should be held as if the brakes were applied. Technician #2
rd
must inform Technician #1 the brake pedal is being held.
9. Technician #1 should open the bleeder valve at this time and allow the brake fluid to flow
into the bottle. Technician#1 must watch the brake fluid passing through the clear hose for
any bubbles. NOTE: If No Brake Fluid Is Flowing, Proceed to "Procedure If No Fluid Is
Passing Through The Right Rear Caliper", Step 20.
10. Technician #2 must hold the pedal to the floor and inform Technician #1 that the pedal is
on the floor.
11. At this time Technician #1 must close the bleeder valve by rotating it to the right as far as it
was turned to the left to ensure the bleeder valve is fully closed.
12. Technician #1 needs to inform Technician #2 that the bleeder valve is closed and to repeat
the brake pedal pumping procedure.
13. Repeat Steps 8 through 12 until only brake fluid, with no bubbles, passes through the clear
hose. CAUTION: Allowing the reservoir to get low on brake fluid will cause air in the
system. The Master Cylinder Reservoir Should Be Filled After Every 3rd Bleed
Procedure With Clean DOT 3 Brake Fluid.
14. When only new, clean brake fluid passes through the clear hose three (3) consecutive
times, close the bleeder valve and install the rubber boot.
15. Repeat Steps 4 through 14 on the left rear caliper, then proceed to Step 16.
16. Repeat Steps 4 through 14 on the right front caliper, then proceed to Step 17.
17. Repeat Steps 4 through 14 on the left front caliper, then proceed to Step 18.
18. Make sure the Master Cylinder is full of DOT 3 brake fluid to the fill line and install the
reservoir cap.
19. Have Technician #2 check the brake pedal by slowly pumping the pedal 10 times to ensure
the pressure holds.
Note: A complete system flush consumes approximately 16 oz. of brake fluid.
