Brake System Bleeding
At 4:47 in
Lake Speed's 90's NASCAR Thunderbird Resurrection: Running 780hp Wide Open at 75 Years Old!
What happens here
Before the car can be driven on the track, the brake system must be thoroughly bled. This involves using a pressure bleeding tool, which consists of a custom-made adapter (fabricated from aluminum bar stock and a pressure gauge from a two-cycle engine pressure tester) that fits into the master cylinder. By applying controlled pressure to the system, air bubbles are forced out through the bleed nipples at each caliper, ensuring a firm and consistent brake pedal. This is a critical safety step to ensure the brakes are fully functional and reliable.
Goal: Bleed the brake lines to ensure a firm brake pedal and reliable braking performance.
