On vehicles equipped with an Anti-lock Brake System (ABS), please refer to the appropriate procedure in this section.
MASTER CYLINDER BLEEDING
- Check the fluid level in the master cylinder reservoir and add fluid as required to bring to the proper level.
- Remove the two brake tubes from the master cylinder.
- Have an assistant depress the brake pedal and hold it in the down position.
- While the pedal is depressed, block off the outlet plug with your finger, then release the brake pedal.
- Repeat the procedure three or four times.
- Reconnect the lines, then bleed the brake system, if needed.
- Clean all the dirt and grease from the wheel cylinder or caliper bleeder plug and remove the protective cap. Connect one end of a clear vinyl tube to the fitting.
- Insert the other end of the tube into a jar which is half filled with brake fluid.
- Have an assistant slowly depress the brake pedal while you slightly open the bleeder plug. Fluid should run out of the tube. When the pedal is at its full range of travel, close the bleeder plug.
- Have your assistant slowly pump the brake pedal. Repeat Step 3 until there are no more air bubbles in the fluid.
- Repeat Steps 1 to 4 for each wheel cylinder or caliper. Add fresh brake fluid to the master cylinder reservoir every few pumps, so that it does not completely drain during bleeding.
