B. Stepping on the pedal to pump brake fluid
Once you have eTher recruited an assistant or set up a brake pedal exchanger, it is time to start pumping the brake fluid through the system. The pumping action helps to push the old brake fluid out and replace it with fresh fluid, removing any air bubbles in the process.
Start by instructing your assistant or using the brake pedal exchanger to slowly press down on the brake pedal. Encourage them to do this gradually, rather than quickly slamming it down. As the pedal is pressed down, the old brake fluid will be forced out through the clear hose, into the container of fresh brake fluid.
As the pedal reaches its maximum depressed position, instruct your assistant or release pressure on the brake pedal exchanger. This will allow the brake pedal to return to its normal position, creating suction and drawing fresh brake fluid into the system. Repeat this pumping action multiple times to ensure that all old fluid is replaced and air bubbles are eliminated.
During this process, you should keep a close eye on the clear hose to monitor the flow of brake fluid. If you notice any air bubbles in the hose, it indicates that there is still air present in the brake system.
