Overview
The ZF 4699.298.013 BRAKE PARTS assembly is a critical OEM genuine component engineered for the internal braking system within ZF construction machinery transmissions. This part functions as a friction-based stopping mechanism, typically positioned within the clutch pack or planetary gear set to manage load holding and emergency deceleration. The SKU 4699.298.013 ensures precise fitment and material integrity, directly replacing worn units to restore transmission control. For full assembly integrity, this brake set works in tandem with the 4699101113: HOUSING and the 4699102157: INPUT shaft components, which provide structural support and torque input alignment.
Symptoms of Failure
- Gradual gear slippage under load: When the brake parts wear, the transmission fails to hold torque, causing the machine to creep or lose power on inclines.
- Delayed engagement or harsh shifting: Worn friction material leads to inconsistent clutch pack pressure, resulting in jerky starts or slow response times.
- Internal oil contamination: Degraded brake particles circulate through the hydraulic system, often visible as dark, metallic debris in the transmission fluid.
- Unusual grinding or whining noise: Metal-on-metal contact from exhausted brake linings produces audible noise during gear changes or braking maneuvers.
