Pressure

NOTE: If any brake component is repaired or replaced such that air is allowed to enter the brake system, the entire bleeding procedure MUST be followed.

NOTE: Prior to bleeding the brakes, the front and rear displacement cylinder pistons must be returned to the topmost position. The preferred method uses a Scan Tool to perform the rehoming procedure. If a Scan Tool is not available, the second procedure may be used, but it is extremely important that the procedure be followed exactly as outlined.

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 Fluid reservoir cover and surrounding area.

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

INSTALL OR CONNECT
1. Bleeder adapter J 35589 to brake fluid reservoir.
2. Bleeder adapter to pressure bleeding equipment. Adjust Pressure bleeding equipment to 35-70 kPa (5-10 psi) and wait for approximately 30 seconds to ensure there is no leakage. Pressure bleed equipment to 205-240 kPa (30-35 psi).
3. Proceed as follows with pressure bleeding equipment connected and pressurized:
4. Attach a clear plastic hose to the rearward bleeder valve on the hydraulic modulator. Place the other end of the hose in a container to collect draining brake fluid. Do not submerge hose end into fluid.
5. 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.
6. Close valve.
7. 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 Hydraulic modulator bleeder valve to 9 Nm (80 inch lbs.).
8. Raise vehicle and suitably support.
9. Flush wheel brakes in sequence. Flush sequence:
- Right rear.
- Left rear.
- Right front.
- Left front

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.
10. Repeat Step 9 on left rear wheel brake.
11. Repeat Step 9 on right front wheel brake.
12. Repeat Step 9 on left front wheel brake.
13. Lower vehicle.
14. Remove bleeder adapter.
15. Replace all rubber components listed under Flushing Procedure.
16. Repeat flushing procedure one more time. Inspect Fluid level in reservoir and fill to correct level if necessary.
17. Fluid reservoir cap.
18. Bleed the entire brake hydraulic system.
