Overview
The ZF 0501.216.815 BRAKE is a critical OEM genuine friction component engineered for heavy-duty construction machinery transmissions. This part functions as a primary stopping mechanism within the planetary gearset assembly, converting hydraulic pressure into clamping force to halt output shaft rotation. Designed to withstand extreme thermal loads and high torque demands, the 0501.216.815 brake assembly ensures precise machine control during loading, grading, and excavation operations. As a direct replacement unit, this SKU integrates seamlessly with the 4699101080: HOUSING to maintain structural integrity under continuous stress.
Symptoms of Failure
- Delayed stopping response: Operators notice a lag between pedal engagement and actual deceleration, often accompanied by a spongy feel in the brake circuit.
- Transmission overheating: Worn friction material generates excessive heat, causing fluid temperatures to spike above 120°C during normal operation.
- Metallic grinding noises: Audible scraping or whining sounds from the transmission housing indicate the brake disc has worn past its service limit.
- Hydraulic fluid contamination: Dark, burnt-smelling oil with visible metallic particles signals internal brake plate degradation.

Compatibility
This brake assembly is specifically designed for ZF WG series powershift transmissions commonly found in wheel loaders, telehandlers, and dump trucks. Compatible models include the WG180, WG200, and WG210 series. It also fits select variants of the 4WG200 and 6WG200 transmissions used in Volvo, Liebherr, and Caterpillar machinery. For proper installation, ensure the 0501329881: HOUSING COVER is torqued to specification and the 0630513065: SNAP RING is fully seated in its groove. Always replace the 0634306309: O-RING during service to prevent fluid bypass.
