Central brake lever 125.46.016 (bare number 125.46.116) is a key element of the mechanical parking brake of HTZ tractors. It serves to transfer force from the operator to the brake band compression mechanism. When the handbrake is activated, the lever turns and, using connections, activates the central brake band 151.46.011, which compresses drum 125.46.101-1, blocking the movement of the tractor.
The lever is connected to the remaining components of the brake assembly, including:
Stretch bracket 125.46.014 - ensures correct tension and adjustment;
Brake lever A5.23.107-1 - intermediate lever in the drive system;
Belt traction 151.46.108 - an element connecting the braking mechanism to the lever.
All of the listed spare parts are included in the parking brake assembly 151.46.001-1, which is installed on wheeled tractors HTZ, such as T-150, T-151, T-156. This solution ensures reliable fixation of the tractor when stopping and on slopes, without requiring a pneumatic system.
