Overview
The ZF 0501.004.615 BRAKE is a critical friction component engineered specifically for the WG150 series transmission. This OEM genuine part functions as the primary holding brake within the planetary gearset, ensuring positive torque lock-up during load-holding and parking maneuvers. Installed directly on the output shaft housing, the 0501.004.615 interfaces with the TRANSMISSION HOUSING and the TRANSMISSION HOUSING to create a sealed braking chamber. The SKU 0501.004.615 is manufactured to ZF’s original equipment tolerances, delivering consistent clamping force and thermal stability under heavy industrial loads.
Symptoms of Failure
- Transmission brake slipping under load: When the 0501.004.615 brake disc wears thin, the transmission fails to hold position on inclines, causing the vehicle to creep forward or backward even with the parking brake engaged.
- Oil leaks around the brake housing: Worn friction material can contaminate the hydraulic fluid, leading to seal degradation and visible oil seepage near the TYPE PLATE area on the transmission casing.
- Delayed engagement or grinding noise: As the brake lining deteriorates, operators may hear a metallic grinding sound during brake application, accompanied by a noticeable lag in stopping response.
- Increased brake pedal travel or spongy feel: Hydraulic pressure loss due to internal wear of the 0501.004.615 assembly results in a soft or extended pedal stroke before the brake engages.

Compatibility
This brake assembly is designed for the ZF WG150 series transmissions. It is also compatible with the WG180 and WG200 models when used with the appropriate GROOVED STUD kit. The 0501.004.615 fits all WG150 variants produced after 2010, including the WG150-3, WG150-5, and WG150-7. For WG180 and WG200 applications, verify the housing bore diameter matches the brake outer diameter before installation.
