ZF 4143.151.015 MULTIDISK BRAKE | OEM Genuine Part

Overview

The ZF 4143.151.015 MULTIDISK BRAKE is a critical friction component engineered for precise torque control within the HL 100 Series and HL 270 Series transmission assemblies. This OEM genuine part functions as a load-holding and dynamic braking element, engaging multiple friction disks to manage rotational energy during gear shifts and stationary operations. Located within the clutch pack housing, the 4143.151.015 ensures smooth power interruption and prevents unintended vehicle movement. The SKU 4143.151.015 is manufactured to ZF’s exacting tolerances, utilizing high-carbon steel reaction plates and sintered bronze friction linings to withstand extreme thermal loads. This multidisk brake directly interfaces with the 4143101025: HOUSING and the 4143301055: HOUSING to form a sealed braking chamber, while the 4143298040: CASE provides structural rigidity for the entire assembly.

Symptoms of Failure

• Transmission brake drag or incomplete disengagement: When the multidisk brake wears unevenly, the friction plates fail to separate fully, causing persistent resistance during acceleration and elevated operating temperatures.
• Oil contamination with metallic particles: Degraded friction material from the 4143.151.015 sheds fine metal shavings into the hydraulic circuit, often visible during oil changes as a gray or bronze sludge in the filter.
• Erratic shift timing or gear slippage: A worn brake pack cannot maintain consistent clamping force, leading to delayed engagement or sudden loss of torque during load-hold operations, particularly in HL 270 Series transmissions.
• Audible grinding or chattering during braking: Warped or glazed friction disks produce a distinct metallic noise when the brake is applied, indicating imminent failure of the 0631329135: SPRING PIN retention system.

Technical Specifications

Compatibility

This genuine ZF multidisk brake is engineered for the HL 100 Series and HL 270 Series transmission families. Based on its friction disk configuration and spline count, the 4143.151.015 is compatible with the following ZF models: WG180, WG200, WG210, and WG250. It also serves as a direct replacement in certain 4WG-200 and 6WG-250 off-highway transmissions. The brake pack is designed to work with the 0501337904: SPEED SENSOR for precise rotational feedback and the 0636101024: CAP SCREW for secure mounting. Always verify your transmission’s serial number against ZF’s compatibility matrix before installation.
