Bleeding the Brake System



BRAKE FLUID BLEEDING

HINT: If any work is done on the brake system or if air in the brake lines is suspected, bleed the air from the system.

NOTICE: Do not let brake fluid remain on a painted surface. Wash it off immediately.





1. FILL BRAKE RESERVOIR WITH BRAKE FLUID
Fluid: SAE J1703 or FMVSS No. 116 DOT3
2. BLEED MASTER CYLINDER

HINT: If the master cylinder has been disassembled or if the reservoir becomes empty, bleed the air from the master cylinder.

a. Disconnect the brake lines from the master cylinder.





b. Slowly depress the brake pedal and hold it.





c. Block off the outlet plug with your finger and release the brake pedal.
d. Repeat (b) and (c) 3 or 4 times.





3. BLEED BRAKE LINE
a. Connect the vinyl tube to the caliper or wheel cylinder bleeder plug.
b. Depress the brake pedal several times, then loosen the bleeder plug with the pedal held down.
c. At the point when fluid stops coming out, tighten the bleeder plug, then release the brake pedal.
Torque: 8.3 Nm (85 kgf-cm, 74 inch lbs.)
d. Repeat (b) and (c) until all the air in the fluid has been bled out.
e. Repeat the above procedure to bleed the air out of the brake line for each wheel.
4. CHECK FLUID LEVEL IN RESERVOIR
Check the fluid level and add fluid if necessary.
Fluid: SAE J1703 or FMVSS No. 116 DOT3

LOAD SENSING PROPORTIONING AND BY-PASS VALVE ON-VEHICLE INSPECTION




1. INSTALL LSPV GAUGE (SST)
SST 09709-29018
2. BLEED AIR FROM FLUID PRESSURE GAUGE
3. RAISE MASTER CYLINDER PRESSURE AND CHECK REAR WHEEL CYLINDER PRESSURE





When inspecting the fluid pressure, inspect the left front and right rear together, and the right front and left rear together.
If the rear wheel cylinder pressure is incorrect, replace the ABS actuator.
4. REMOVE LSPV GAUGE (SST) AND BLEED BRAKE SYSTEM
5. CHECK FOR LEAKS
