Description
Overview:
The Brake Piston Seal Kit for Thwaites 5 and 6 tonne dumpers is a replacement set of sealing rings designed to restore and maintain hydraulic braking performance. The seals are made from hard‐wearing, oil‐resistant elastomer materials that cope with heat, pressure and abrasive site conditions. Correctly fitted, they keep hydraulic pressure stable, protect against fluid leaks, and help prevent dirt and water ingress. Each seal is sized to suit the brake piston lands used on Thwaites dumpers, giving a reliable, snug fit without modification. Ideal for workshop overhauls or routine preventative maintenance, this kit is a direct replacement to keep braking systems responsive and consistent on popular machines such as the Thwaites 5 Tonne and 6 Tonne models.
Key Features:
- Durable elastomer construction for long service life in demanding site conditions
- Maintains a tight hydraulic seal to restore pedal feel and consistent braking force
- Direct-fit dimensions for Thwaites 5 and 6 tonne dumpers to simplify installation
- Helps prevent brake fluid leaks and blocks contamination from dust, water and grit
- Supports smooth piston movement, reducing wear on pistons and bores
- Suitable for routine servicing or full brake overhauls to reduce downtime
- Can be fitted with standard workshop tools and correct assembly lubricant
- Cost-effective way to protect axles and brake internals by stopping early seal failure
Typical Applications:
Used during brake services, repairs or rebuilds on Thwaites site dumpers to cure fluid leaks, soft or fading brakes, and poor brake response. Suitable for scheduled maintenance, pre‐hire checks, or to refresh seals after contamination or storage. Helps keep dumpers safe and operational on construction, landscaping and utility worksites.
