Bleeding the brake system on a car involves flushing out air from the brake lines and replacing old brake fluid with fresh fluid. Air gets into the brake lines when a section of the brake system is disconnected or when the brake pads become depleted to the point that the brake fluid level in the reservoir falls too low.Continue Reading
To begin, raise the car off the ground using a hydraulic lift or a jack. Drain off the old fluid in the reservoir using a turkey baster or syringe. Top up the cylinder with flesh brake fluid. Ensure that it doesn’t fall below halfway throughout the bleeding process to prevent more air from getting into the system.
Loosen the bleeder bolts using a box wrench. Spraying a little oil on the bolts a day before can help loosen them. A cautious hammer tap can also help to disintegrate any present corrosion. Leave the bleeder bolts closed.
Next, pour about an inch of fresh brake fluid into a bottle. Push one end of a clear plastic tube over the bleeder bolts, with the other end in the bottle. The fluid in the bottle ensures that air is not sucked back into the brake system. Next, put a piece of wood under the brake pedal to stop it from going too far after the line pressure release.
Next, get an assistant to press the brake pedal continuously. Loosen the bleeder plug about half a turn, and close it once the fluid drip stops. Repeat this process until fresh fluid flows through the tube. Bleed the remaining three brake lines using the same procedure.Learn more about Brakes
