Classic Car One Person Brake Bleeding
|Rear Brake Caliper.|
How to Steps:
- Jack up and support your car with jackstands. Block a wheel on both sides by choosing a wheel that is not being worked on, that is in contact with the floor. Be sure to shake the car to check that the stands are set correctly, before putting human body parts under the car. Remove the wheels for easier access to brake bleeders. Do not remove the brake drums. Release the parking brake. The sequence of brake bleeding is to start with the wheel farthest from the master cylinder to then proceed to the next farthest and so on. Or, the right-rear wheel first, then the left rear, right front and the left front.
- Take your dry water bottle and add enough new fresh brake fluid to create an inch or so of fluid at the bottom of the bottle, so the vacuum hose will be submerged in the fluid.
- Take the other end of the vacuum hose and install the hose to the bleeder valve nipple. Ensure, the hose has a tight fit.
- Slightly loosen the bleeder valve usually about ⅛ to ¼ turn. Leave the bleeder wrench on the valve.
- Position the bottle just below the wheel so it can be viewed while pumping the brake pedal by hand.
- With the bottle in view, slowly pump the pedal until air bubbles are no longer present. Normally, three to four strokes will be needed to purge air bubbles from the hose. With the absence of air bubbles coming from the hose during pumping, pump three to five additional strokes to ensure the lines are purge the old fluid out of the caliper or wheel cylinder. When finished removing old fluid and air, retighten the bleeder valve.
- Top off the master cylinder with new brake fluid. Note: If you have to pump several strokes on one wheel you may need to add fluid to the master cylinder before moving on to the next wheel. Always maintain fluid in the master cylinder. If the master cylinder runs dry, air will enter the brake system and the process will need to be repeated.
- Bleed all four wheels. Remember to check the master cylinder fluid level after each wheel is bled. Ensure all bleeder valves are shut immediately after bleeding. Note: Flushing the entire system usually requires about one quart of brake fluid.
