Overview
The ZF 4143.151.007 MULTIDISK BRAKE is a critical friction component engineered for precise torque interruption within the HL 100 and HL 270 series transmission assemblies. This OEM genuine part functions as a primary holding brake, engaging multiple friction disks to halt output shaft rotation under load. Located within the clutch pack housing, the SKU 4143.151.007 directly interfaces with the 4143101016 HOUSING and the 4143301039 HOUSING to maintain hydraulic pressure integrity. When installed with the correct 0501318136 GASKET and secured by 0636101084 CAP SCREW, this multidisk brake ensures reliable stopping force for industrial drivetrains.
Symptoms of Failure
- Delayed engagement or brake drag: Worn friction disks cause hesitation when engaging the brake, leading to sluggish response times in HL 100 series transmissions.
- Transmission overheating during braking cycles: Excessive heat generation from slipping multidisk packs indicates the 4143.151.007 has lost its coefficient of friction.
- Hydraulic fluid contamination with metallic particles: Degraded brake material sheds debris into the oil circuit, often detected during routine filter inspections.
- Intermittent loss of holding torque on inclines: The brake fails to maintain stationary position under load, a common failure mode in WG200 applications.
