When a new brake master cylinder has been installed or the system has been emptied or partially emptied, it should be primed to prevent air from getting into the system.
Disconnect the brake master cylinder tubes from the side of the master cylinder.
NOTEOriginal equipment lines are not intended to be used during this procedure.
Install the 2 short brake tubes with the ends submerged in the brake master cylinder reservoir and fill the brake master cylinder reservoir with DOT 3 motor vehicle brake fluid.
- Have an assistant pump the brake pedal until clear fluid flows from both brake tubes without air bubbles.
- Remove the 2 short brake tubes and install the 2 master cylinder brake tube fittings.
Bleed each brake tube at the brake master cylinder as follows:
- Have an assistant pump the brake pedal and then hold firm pressure on the brake pedal.
- Loosen the rear brake tube fittings until a stream of brake fluid comes out. Have an assistant maintain pressure on the brake pedal while tightening the brake tube fitting.
- Repeat this operation until clear, bubble-free fluid comes out.
- Refill the brake master cylinder reservoir as necessary. REPEAT the bleeding operation at the front brake tube.
- While the assistant maintains pressure on the brake pedal, tighten the master cylinder brake tubes to 13 ft. lbs. (18 Nm).
