Bleeding the Brake System

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 brake 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 DOTS
2. REMOVE BATTERY
3. 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.

4. BLEED BRAKE LINE
a. Connect the vinyl tube to the caliper.
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 procedure to bleed the air out of the brake line for each wheel.
5. CHECK FLUID LEVEL IN RESERVOIR
Check the fluid level and add fluid if necessary.
Fluid: SAE J1703 or FMVSS No. 116 DOT3

2ZZ-GE engine:

When inspecting the fluid pressure, inspect the left font and right rear together, and the right front and left rear together.
If the rear fluid pressure is incorrect, replace the P valve assembly.
