Pressure Flushing

WARNING:
- Use only SUPREME 11 (PN. 1052542), or equivalent DOT 3 brake fluid from a clean, sealed container. Do not use fluid front an open container that may be contaminated with water. Improper or contaminated fluid could result in damage to components, or loss of braking, with possible personal injury.
- Overfilling the reservoir must be avoided due to the potential for overflow onto the nearby catalytic converters in the exhaust system. Brake fluid is flammable, and contact with hot exhaust components could result in a fire and possible personal injury.

CAUTION:
- If evidence of contamination is present in the vehicle's brake fluid, the entire brake system must be flushed.
- The system must be flushed if there is any doubt about the condition of fluid in the system or if fluid has been used which contains the slightest trace of mineral oil (from such things as engine oil, transmission fluid, etc.).
- If contamination is found, all rubber components must be replaced. Components which must be replaced include: brake hose assemblies, master cylinder rubber parts, brake caliper and wheel cylinder boots and seals, brake modulator, and brake solenoid valves.
- After all rubber components have been replaced, the entire brake system must be re-flushed.
- Once the second flushing procedure has been performed, a complete system bleed must be performed. Bleeding
- 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.

NOTE: - Tools Required:
- J 29532 Diaphragm type brake bleeder, or equivalent bleeder.
- J 35589 Compact brake bleeder adapter, or equivalent adapter.

1. Clean brake fluid reservoir cover and surrounding area.
2. Remove brake fluid reservoir cover.
3. Remove any remaining brake fluid in reservoir.
4. Refill brake fluid reservoir with clean DOT 3 brake fluid to proper level.
5. Install adapter to brake fluid reservoir.
6. Install and adjust adapter to pressure bleeding equipment.
a. Adjust pressure bleeding equipment to 35 to 70 kPa (5 to 10 psi) and wait for approximately 30 seconds to ensure there is no leakage.
b. Adjust pressure bleed equipment to 205 to 240 kPa (30 to 35 psi).
7. Proceed as follows with pressure bleeding equipment connected and pressurized:
a. Attach a clear plastic hose to the rearward bleeder valve on the brake 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.
e. Tighten ABS brake modulator bleeder valves to 9 Nm (80 inch lbs.).
8. Proceed as follows with pressure bleeding equipment connected and pressurized:
a. Remove traction control module bolt to bracket to access bleeder valves.
b. Attach a clear plastic hose to the right side bleeder valve on the traction control module. Place the other end of the hose in a container to collect draining brake fluid. Do not submerge hose end into fluid.
c. 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.
d. Close valve.
e. Repeat above procedure for the left side bleeder valve until clean brake fluid flows or until at least 118 ml (4 ounces) of fluid is accumulated.
f. Tighten the:
- TCM bleeder valves to 9 Nm (80 inch lbs.).
- TCM bolt to bracket to 5 Nm (44 inch lbs.).
9. Raise vehicle and suitably support.
10. Flush brakes using the sequence shown.

(1)Right Rear (2)Left Rear (3)Right Front (4)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.
d. Tighten the:
- Front caliper bleeder valve to 13 Nm (115 inch lbs.).
- Rear wheel cylinder bleeder valve to 7 Nm (62 inch lbs.).

CAUTION: Make sure the bleeder valves do not leak.

11. Lower vehicle.
12. Remove bleeder adapter.
13. Replace all rubber components.
- Components which must be replaced include: brake hose assemblies, master cylinder rubber parts, brake caliper and wheel cylinder boots and seals, brake modulator, and brake solenoid valves.

14. Repeat flushing procedure one more time. Inspect Brake fluid level in reservoir and fill to correct level if necessary.

15. Install brake fluid reservoir cap.
16. Bleed the entire brake hydraulic system. Bleeding
