Pressure Flush

NOTE: Pressure bleeding equipment can be used to perform the flush procedure. The pressure bleeding equipment used for flushing must be of the diaphragm type. It must have a rubber diaphragm between the air supply and the brake fluid to prevent air, moisture, and other contaminants from entering the hydraulic system.

CLEAN
1. Fluid reservoir cover and surrounding area.

REMOVE OR DISCONNECT
2. Fluid reservoir cover.
3. Any remaining brake fluid in reservoir.
4. Refill reservoir with clean DOT 3 brake fluid to proper level.

INSTALL OR CONNECT
5. Bleeder adapter J 35589 to brake fluid reservoir.
6. Bleeder adapter to pressure bleeding equipment.
7. Pressure bleeding equipment to 35-70 kPa (5-10 psi) and wait for approximately 30 seconds to insure there is no leakage.
8. Pressure bleed equipment to 205-240 kPa (30-35 psi).
9. Proceed as follows with pressure bleeding equipment connected and pressurized:
a. Attach a clear plastic hose to the rearward bleeder valve on the ABS hydraulic modulator. Place the other end of the hose in a container to collect draining brake fluid. Do not submerge hose end into fluid.
b. Slowly open bleeder valve and allow fluid to flow until clean brake fluid flows or until at least 118 ml (4 ounces) of fluid is accumulated.
c. Close valve.
d. Repeat above procedure for the forward bleeder valve until clean brake fluid flows or until at least 118 ml (4 ounces) of fluid is accumulated. Tighten ABS hydraulic modulator bleeder valve to 9 Nm (80 inch lbs.).
10. Raise vehicle and suitably support.Flush sequence:
- Right rear.
- Left front.
- Right front.
- Left rear.
11. Flush wheel brakes in sequence shown above.
a. Attach bleeder hose to bleeder valve at each wheel and place the other end into a container to collect draining brake fluid. Do not submerge hose end in fluid.
b. Slowly open bleeder valve and allow fluid to flow.
c. Close valve when clean brake fluid begins to flow or at least 235 ml (8 ounces) of fluid is accumulated.
12. Repeat step 11 on left rear wheel brake.
13. Repeat step 11 on right front wheel brake.
14. Repeat step 11 on left front wheel brake.
15. Lower vehicle.
16. Remove bleeder adapter.
17. Replace all rubber components.
18. Repeat flushing preparation and flushing procedure Steps 4-16 one more time.
19. Fluid level in reservoir and fill to correct level if necessary.

INSTALL OR CONNECT
20. Fluid reservoir cap.
21. Bleed the entire brake hydraulic system.
