It is necessary to bleed the brake system of air whenever a hydraulic component, of the system, has been rebuilt or replaced, or if the brakes feel spongy during application.

Your car has a diagonally split brake system. Each side of this system must be bled as an individual system. Bleed the right rear brake, left front brake, left rear brake and right front brake. Always start with the longest line from the master cylinder first.


WARNING
When bleeding the system(s) never allow the master cylinder to run completely out of brake fluid. Always use DOT 3 heavy duty brake fluid or the equivalent. Never reuse brake fluid that has been drained from the system or that has been allowed to stand in an opened container for an extended period of time. If your car is equipped with power brakes, remove the reserve vacuum stored in the booster by pumping the brake pedal several times before bleeding the brakes.

  1. Clean all of the dirt away from the master cylinder filler cap.
  2.  
  3. Raise and support the car on jackstands. Make sure your car is safely supported and it is raised evenly front and back.
  4.  

If the master cylinder has been overhauled or if air is present in it, 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.

If the master cylinder has to be bled, it is recommended that the master cylinder be bled while it is off the car if a new one is being installed or it can be bled on the car if the problem is within the brake system. Either way it is recommended that a inexpensive master cylinder bleeding kit be purchased at your local parts dealer. This will make bleeding the master cylinder easier and also help to insure that the master cylinder is bled properly.

To bleed the master cylinder, follow the directions on your bleeding kit or have a friend pump up the brakes while you crack one line at a time on the master cylinder until clear brake fluid runs out of the lines.

  1. Starting with the right rear wheel cylinder. Remove the dust cover from the bleeder screw. Place the proper size box wrench over the bleeder fitting and attach a piece of rubber tubing (about three feet long and snug fitting) over the end of the fitting.
  2.  
  3. Submerge the free end of the rubber tube into a container half filled with clean brake fluid.
  4.  
  5. Have a friend pump up the brake pedal and then push down to apply the brakes while you loosen the bleeder screw. When the pedal reaches the bottom of its travel close the bleeder fitting before your friend release the brake pedal.
  6.  
  7. Repeat Step 5 until air bubbles cease to appear in the container in which the tubing is submerged. Tighten the fitting, remove the rubber tubing and replace the dust cover.
  8.  
  9. Repeat Steps 3 through 6 to the left front wheel, then to the left rear and right front.
  10.  

Refill the master cylinder after each wheel cylinder or caliper is bled. Be sure the master cylinder top gasket is mounted correctly and the brake fluid level is within the proper limits.

  1. After bleeding the brakes, pump the brake pedal several times, this ensures proper seating of the rear linings and the front caliper pistons.
