Brake Bleeding: Service and Repair

BRAKE FLUID BLEEDING

HINT: If any work is done on the brake system or if air is suspected in the brake lines, 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
Check the fluid level in the reservoir after bleeding each wheel. Add fluid, if necessary.

Fluid: SAE J1 703 or FMVSS No. 116 DOT 3

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 plugs with your fingers, and release the brake pedal.
d. Repeat (b) and (c) 3 or 4 times.





3. CONNECT VINYL TUBE TO BRAKE CALIPER BLEEDER PLUG
Insert the other end of the tube in a half-full container of brake fluid.

NOTICE: Bleed air of the rear brake first. If the front brake is bled first, rear brake air cannot be bled.

4. BLEED BRAKE LINE
a. Slowly depress the brake pedal several times.
b. While an assistant depresses the pedal, loosen the bleeder plug until fluid starts to run out. Then tighten the bleeder plug.
c. Repeat this procedure until there are no more air bubbles in the fluid.

Torque (Bleeder plug): 8.3 Nm (85 kgf.cm, 74 inch lbs.)

5. REPEAT PROCEDURE FOR EACH WHEEL
6. w/ VSC: BLEED BRAKE ACTUATOR
a. Remove the reservoir cap.





b. Install the SST to the reservoir.
SST 09992-00242, 09992-00350
c. Connect the vinyl tube to the bleeder plug of the brake actuator.
d. Using SST, apply the pressure described below to the reservoir.

Pressure: 98.1 kPa (1.0 kgf.CM2, 14.2 psi)

e. Loosen the bleeder plug.





f. Bleed the air out of the brake actuator, tighten the bleeder plug.

Torque: 8.3 Nm (85 kgf.cm, 74 inch lbs.)

7. CHECK FLUID LEVEL IN RESERVOIR
Check the fluid level and add fluid if necessary.

Fluid: SAE J1703 or FMVSS NO. 116DOT3
