-- Insert the Brake Servo Release Tool T10006A as shown and pull in the direction of the driver seat. When doing this, counter-hold at the brake pedal (the pedal must not be allowed to move backward at this time). The mount retaining tabs -3- will thereby be pressed off the ball head of the push rod -2-.

For ease of illustration separating the brake pedal from the brake booster is shown with the pedal assembly removed.

-- Pull the Brake Servo Release Tool T10006A and brake pedal together toward the driver seat (as a result, the brake pedal is removed from the pushrod ball head).
