Handbrake (parking brake) - adjustment
Parking brake (handbrake) The T4 conveyor is adjusted under the car at the parking brake equalizing lever in the place shown in fig. 422. During normal operation, there is no need to adjust the parking brake, as it is adjusted automatically as a result of the operation of the main brake system. But if it is necessary to replace the linkage of the parking brake or brake shield, it is necessary to remove the brake drum and perform the following operations.

♦ Reinstall the brake drum, then the wheels, release the parking brake.
The wheels should turn freely without resistance. ♦ Apply the parking brake and check that the wheels do not brake after the T4 handbrake is released. If the brake pads have been set to the basic position in the manner described above, the initial travel of the parking brake lever and foot brake pedal will be greater than normal. This will disappear automatically after a few brakings as the self-adjusting mechanisms will bring the brake pads into position.
