Brake Bleeding: Service and Repair
With Traction Control System (TCS)
A: GENERAL RULES FOR EFFECTIVE BLEEDING
1. Start with the brakes (wheels) connecting to the secondary chamber of the master cylinder.
2. The time interval between two brake pedal operations (from the time when the pedal is released to the time when it is depressed another time) shall
be approximately 3 seconds.
3. The air bleeder on each brake shall be released for 1 to 2 seconds.
B: BLEEDING PROCEDURE
CAUTION:
^
The FMVSS No. 116, fresh DOT 3 or 4 brake fluid must be used.
^
Cover bleeder with waste cloth, when loosening it, to prevent brake fluid from being splashed over surrounding parts.
^
Avoid mixing different brands of brake fluid to prevent degrading the quality of the fluid.
^
Be careful not to allow dirt or dust to get into the reservoir tank.
NOTE:
^
During bleeding operation, keep the brake reserve tank filled with brake fluid to eliminate entry of air.
^
Brake pedal operating must be very slow.
^
For convenience and safety, it is advisable to have two man working.
1. Make sure that there is no leak from joints and connections of the brake system.
2. Fit one end of vinyl tube into the air bleeder and out the other end into a brake fluid container.
3. Slowly depress the brake pedal and keep it depressed. Then, open the air bleeder to discharge air together with the fluid.
Release air bleeder for 1 to 2 seconds.
Next, with the bleeder closed, slowly release the brake pedal.
Repeat these steps until there are no more air bubbles in the vinyl tube.
Allow 3 to 4 seconds between two brake pedal operations.
CAUTION: Cover bleeder with waste cloth, when loosening it, to prevent brake fluid from being splashed over surrounding parts.
NOTE: Brake pedal operating must be very slow.
4. Tighten air bleeder securely when no air bubbles are visible.
Air bleeder tightening torque: 8 ± 1 Nm (0.8 ± 0.1 kg-m, 5.8 ± 0.7 ft. lbs.)
5. Perform these steps for the brakes connecting to the secondary chamber of master cylinder, first, and then for the ones connecting to primary
chamber. With all procedures completed, fully depress the brake pedal and keep it in that position for approximately 20 seconds to make sure that
there is no leak evident in the entire system.
