Brake Bleeding: Service and Repair
Air Bleeding
PROCEDURE
CAUTION:
^
The FMVSS No. 116, fresh DOT3 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.
^
Be extremely careful not to spill brake fluid. Brake fluid spilt on the vehicle body will harm the painted surface; wash it off quickly if spilt.
NOTE:
^
Start with the brakes (wheels) connected to the secondary chamber of the master cylinder.
^
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)
should be approximately 3 seconds.
