Bleeding the Brake System

Print


CAUTION
Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with the eyes and wash your hands thoroughly after handling brake fluid. If you do get brake fluid in your eyes, flush your eyes with clean, running water for 15 minutes. If eye irritation persists, or if you have taken brake fluid internally, IMMEDIATELY seek medical assistance.

On vehicles equipped with anti-lock brakes (ABS), please refer to the appropriate procedure later in this section.

If any maintenance or repairs were performed on the brake system, or if air is suspected in the system, the system must be bled. If the master cylinder has been overhauled or if the fluid reservoir was run dry, start the bleeding procedure with the master cylinder. Otherwise (and after bleeding the master cylinder), start with the wheel cylinder which is farthest from the master cylinder (longest hydraulic line).


WARNING
Clean, high quality brake fluid is essential to the safe and proper operation of the brake system. You should always buy the highest quality brake fluid that is available. If the brake fluid becomes contaminated, drain and flush the system, then refill the master cylinder with new fluid. Never reuse any brake fluid. Any brake fluid that is removed from the system should be discarded. Also, do not allow any brake fluid to come in contact with a painted surface; it will damage the paint.

MASTER CYLINDER



See Figures 1, 2 and 3


CAUTION
Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with the eyes and wash your hands thoroughly after handling brake fluid. If you do get brake fluid in your eyes, flush your eyes with clean, running water for 15 minutes. If eye irritation persists, or if you have taken brake fluid internally, IMMEDIATELY seek medical assistance.

BRAKE SYSTEM



See Figure 4

Start the brake system bleeding procedure on the wheel cylinder that is the furthest away from the master cylinder. To bleed the brakes you will need a supply of brake fluid, a long piece of clear vinyl tubing and a small container that is half full of brake fluid.

  1. Clean all the dirt and grease from the caliper or wheel cylinder bleeder plug and remove the protective cap. Connect one end of a clear vinyl tube to the fitting.
  2.

  1. Insert the other end of the tube into a jar which is half filled with brake fluid.
  2.  
  3. Have an assistant slowly depress the brake pedal while you open the bleeder plug 1 / 31 / 2 of a turn. Fluid should run out of the tube. When the pedal is at its full range of travel, close the bleeder plug.
  4.  
  5. Have your assistant slowly pump the brake pedal. Repeat Step 3 until there are no more air bubbles in the fluid.
  6.  
  7. Repeat the procedure for each wheel cylinder. Add brake fluid to the master cylinder reservoir every few pumps, so that it does not completely drain during bleeding.
