ZF 0501.330.090 BRAKE | OEM Genuine Part

Overview

The ZF 0501.330.090 BRAKE is a critical OEM genuine component designed for high-stress braking applications within ZF construction machinery transmissions. This part functions as a friction-based stopping mechanism, engaging directly within the planetary gear set to halt output shaft rotation. As an integral element of the hydraulic brake pack, the 0501.330.090 ensures precise modulation and holding torque under heavy loads. When paired with the 4699101093: HOUSING, it forms a sealed assembly that channels hydraulic pressure for consistent engagement. The SKU 0501.330.090 is engineered to withstand extreme thermal cycling and particulate contamination common in earthmoving equipment.

Symptoms of Failure

• Transmission brake slippage under load: When the 0501.330.090 wears, operators notice the machine creeping on inclines or failing to hold position during digging cycles.
• Delayed brake engagement or “soft pedal”: Worn friction material causes a spongy response, requiring increased pedal travel before the brake locks the driveline.
• Metallic grinding noises from the transmission housing: Advanced wear exposes the steel backing plate, producing a distinct scraping sound during brake application.
• Hydraulic fluid contamination with dark debris: Degraded friction lining particles circulate through the system, often clogging the 0634303936: O-RING sealing surfaces and accelerating internal leakage.

Technical Specifications

Compatibility

This brake disc is primarily compatible with ZF WG180, WG200, and WG210 series powershift transmissions used in wheel loaders, telehandlers, and graders. It also fits select ZF 4WG-200 and 6WG-200 variants where the brake pack uses a 180mm outer diameter friction element. For proper installation, verify the condition of the 4699301175: HOUSING and 4699301041: COVER to ensure correct axial clearance. The 0501.330.090 replaces older part numbers 0501.330.080 and 0501.330.070 in updated brake packs.
