Overview
The ZF 0501.215.886 BRAKE is an OEM genuine friction component engineered for the final drive assembly of heavy-duty construction machinery transmissions. This part functions as a service brake or parking brake element within the planetary gear set, converting hydraulic pressure into clamping force to halt rotating shafts. The SKU 0501.215.886 is specifically designed to withstand extreme thermal loads and high torque demands found in wheel loaders, dozers, and graders. When paired with a robust 5838109012: DIFFERENTIAL, this brake ensures consistent stopping power under heavy payloads. Its sintered metal friction lining provides reliable engagement without fade, even after repeated cycling in demanding job site conditions.
Symptoms of Failure
- Delayed stopping or brake fade: When the ZF 0501.215.886 wears thin, operators notice increased stopping distance, especially when the machine is fully loaded. This symptom often triggers searches for “ZF brake slipping under load” or “transmission brake not holding.”
- Oil contamination in brake chamber: A worn seal or degraded friction material allows transmission fluid to bypass, causing “brake drag and oil leaks from final drive.” You may observe dark, burnt-smelling oil during routine drain intervals.
- Grinding or squealing noise during engagement: Metal-on-metal contact from a fully worn brake disc produces a high-pitched squeal or grinding sound. This is a classic indicator that the friction material has been completely consumed.
- Reduced parking brake holding power: On inclines, the machine may roll slightly after the parking brake is applied. This failure mode is frequently searched as “construction equipment parking brake fails on slope.”

Compatibility
This brake disc is a direct fit for ZF WG180, WG200, and WG310 series powershift transmissions commonly used in construction machinery. It also applies to certain ZF 4WG-200 and 6WG-200 variants found in articulated dump trucks and telehandlers. For optimal performance, always replace the brake disc alongside the 0750117075: TAPER ROLLER BEARING which supports the output shaft. Additionally, verify the condition of the 2093209023: DIFFERENTIAL and the 5838300626: DIFFERENTIAL HOUSING during brake service, as wear in these components can accelerate brake failure.
