Bleeding the Brake System

BLEEDING





HINT: If any work is done on the brake system or 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 the reservoir becomes empty, bleed the master cylinder.





a. Disconnect the 2 or 3 brake lines from the master cylinder.
b. Slowly depress the brake pedal and hold it.





c. Block off the outer 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.
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.
d. Repeat (b) and (c) until all the air in the fluid has been bled out.
e. Repeat the above procedure to bleed the brake line for each wheel.
Torque: (Bleeder plug) 8.3 Nm (85 kgf-cm, 73 inch lbs.)
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
SST 09709-29018
5. CHECK FOR LEAKS
