Overview
The ZF 0501.215.756 BRAKE is a critical OEM genuine component engineered for the demanding environment of construction machinery transmissions. This part functions as a primary braking element within the clutch pack assembly, providing the necessary friction to engage and disengage power flow in heavy-duty drivetrains. Specifically, the SKU 0501.215.756 sits between the rotating drum and the piston, converting hydraulic pressure into mechanical stopping force. Without this brake, the transmission cannot hold torque under load, leading to operational inefficiency. For a complete rebuild, ensure the 4699101046: HOUSING is inspected for wear, as it directly supports the brake assembly.
Symptoms of Failure
- Delayed engagement or gear slipping under load: When the 0501.215.756 brake wears thin, the transmission fails to lock up, causing the machine to creep or lose power during digging or lifting operations.
- Erratic shifting and harsh engagement: A worn brake surface can cause sudden, jarring shifts as the clutch pack struggles to modulate pressure, often accompanied by a grinding noise.
- Oil contamination with metallic debris: As the friction material degrades, fine metal particles enter the hydraulic fluid, visible during oil changes or filter inspections. This accelerates wear on adjacent components like the 4699301109: HOUSING.
- Overheating transmission fluid: Slipping brakes generate excessive heat, leading to burnt-smelling oil and potential seal failure. Check the 4699301017: BEARING COVER for heat discoloration.

Compatibility
This brake disc is primarily designed for ZF WG series transmissions used in construction machinery, including the WG180, WG200, and WG210 models. It also fits select ErgoPower and Ecolite variants where the clutch pack uses a 215mm outer diameter friction element. For proper installation, verify that the 4699301085: COVER is free from scoring, as misalignment can cause premature brake failure. Always replace the brake in sets with the corresponding steel separator plates to maintain even clamping force.
