Description
Overview:
The Handbrake Return Spring is a Genuine Thwaites part designed for site dumpers, including the MACH 865 and MACH 866 6 ton (approx. 6.1 tonnes) models. Made from durable spring steel, it provides the correct return force so the handbrake lever and linkage return to the off position after use. This helps maintain reliable brake release, consistent performance, and safe operation on site. The helical coil form with hooked ends is engineered for dependable tension and long service life in harsh working conditions. Supplied to original Thwaites specification, it is suitable for routine servicing or replacing a tired or stretched spring during repairs, restoring proper handbrake feel and function across the wider MACH series where specified.
Key Features:
- Genuine Thwaites part for assured fit and function on specified MACH models
- Tough spring steel construction for long-lasting elasticity and strength
- Correct spring rate to restore positive handbrake return and consistent release
- Robust finish suited to wet, muddy, and abrasive site environments
- Simple, direct replacement to reduce downtime during maintenance
- Made to OEM specification for reliable alignment with existing levers and linkages
- Helps maintain safety compliance by ensuring the handbrake fully returns
- Cross-reference: replaces Thwaites part number T20851
Typical Applications:
Used during routine brake servicing or when the handbrake fails to return properly on Thwaites site dumpers. Ideal for fixing weak, stretched, or corroded springs to restore proper handbrake action. Suitable for workshop repairs, on-site maintenance, and fleet upkeep where reliable parking brake performance is essential.

Parking brake return spring, hand brake tension spring, parking brake recoil spring, dumper handbrake spring, brake lever return spring.
