Important:
• | If evidence of contamination is present in the vehicle's brake
fluid, flush the entire brake system using one of the procedures outlined
below. |
• | After flushing the entire brake system, replace the following
rubber components. |
- | Master cylinder rubber parts |
- | Brake caliper and wheel cylinder boots and seals |
• | Re-flush the system after all of the rubber components have been
replaced. Use one of the following procedures outlined below. |
• | Flush the system if any of the following conditions exist: |
• | There is a concern that the fluid is contaminated. |
• | The fluid contains traces of mineral oil, engine oil, or transmission
fluid. |
Pressure Flush
Tools Required
J 35589 Master Cylinder
Bleeder Adapter
Notice: 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 a 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 the fluid reservoir cover and the surrounding areas.
- Remove the fluid reservoir cover.
- Remove any remaining brake fluid in the reservoir.
- Refill the reservoir to the proper level using clean DOT-3 brake
fluid.
- Install the J 35589
to brake fluid reservoir.
- Install the J 35589
to the pressure bleeding equipment.
- Adjust the pressure bleeding equipment to 35-70 kPa
(5-10 psi). Wait for approximately 30 seconds in order to ensure that
there is no leakage.
- Adjust the pressure bleeding equipment to 205-240 kPa
(30-35 psi).
- Attach a clear plastic hose to the rearward bleeder valve on the
hydraulic modulator.
Place the other end of the hose in a container in order to collect the
draining brake fluid. Do not submerge the hose end into the fluid.
- Slowly open the bleeder valve. Allow the fluid to flow until clean
brake fluid flows or until at least 118 ml (4 oz) of fluid is accumulated.
- Close the valve.
- Attach a clear plastic hose to the forward bleeder valve on the
hydraulic modulator.
Place the other end of the hose in a container in order to collect the
draining brake fluid. Do not submerge the hose end into the fluid.
- Slowly open the bleeder valve. Allow the fluid to flow until clean
brake fluid flows or until at least 118 ml (4 oz) of fluid is accumulated.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Close the valve.
Tighten
Tighten the hydraulic modulator bleeder valve to 9 N·m
(80 lb in).
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Flush the brakes in the following order:
- Attach the bleeder hose to the bleeder valve at each wheel.
Place the other end of the hose into a container in order to collect
the draining brake fluid. Do not submerge the hose end into the fluid.
- Slowly open the bleeder valve and allow the fluid to flow.
- Close the valve when the clean brake fluid begins to flow or at
least 235 ml (8 oz) of fluid is accumulated.
- Lower the vehicle.
- Remove the J 35589
.
- Replace the following rubber components:
• | Master cylinder rubber parts |
• | Brake caliper and wheel cylinder boots and seals |
- Repeat the entire pressure flushing procedure one more time.
- Inspect the fluid level in the reservoir. Fill the reservoir to
the correct level, if necessary.
- Install the fluid reservoir cap.
- Bleed the entire brake hydraulic system. Refer to
Hydraulic Brake System Bleeding
.
