The brakes should be bled whenever a brake line, caliper, wheel cylinder, or master cylinder has been removed or when the brake pedal is low or soft. The bleeding sequence (except for front wheel drive models) is, right rear wheel, left rear wheel, left front wheel, and right front wheel. The bleeding sequence for front wheel drive models is, left rear wheel, right front wheel, right rear wheel and left front wheel.
Some 1976 and later rear wheel drive models don't have a bleeder fitting on the left rear brake. Both rear brakes must be bled from the right rear.
- Check the master cylinder fluid level. If necessary, add fluid to bring the level up.
- Remove the bleeder cap at the wheel cylinder or caliper. Connect a rubber hose to the bleeder and immerse the other end in a glass container half filled with brake fluid.
- Have an assistant depress the brake pedal to the floor, and then pause until the fluid flow stops and the bleeder nipple is closed.
- Allow the pedal to return and repeat the procedure until a steady, bubble-free flow is seen.
- Tighten the bleeder valve and replace the cap. Move on to the next wheel in sequence.
Frequently check the master cylinder level during this procedure. If the reservoir goes dry, air will enter the system and it will have to be rebled.
