Distribution blocks were used when going from side to side. Pictured here is the rear distribution block that Gonier and Cramer mounted on the inside of the driver's side framerail. Gonier filled the CPP master cylinder with brake fluid, then started the bleed process. Bleeding the brake lines is a simple, but vital step. Air in the system will cause stopping problems. Two people are needed for this task, one to step on the pedal and one person to manually bleed the system.
