Product Description
The LoadForce TA300 Trojan-Style Hydraulic Brake Caliper is a premium hydraulic disc brake caliper designed as a direct replacement for Trojan AU and Trigg A200 hydraulic trailer brake calipers. Engineered specifically for Australian trailers, caravans and marine applications, the TA300 combines a corrosion-resistant body with a billet stainless steel piston to deliver dependable braking performance and significantly improved durability over older designs.
One of the most common problems with original Trojan AU and Trigg A200 calipers is piston swelling and seizure caused by ageing phenolic (plastic) pistons. The LoadForce TA300 replaces this design with a precision-machined billet stainless steel piston, providing smoother brake operation, improved reliability and longer service life.
The TA300 suits brake rotors between 12 mm and 15 mm thick and is compatible with both hydraulic override couplings and Electric Over Hydraulic (EOH) brake actuators, including the AL-KO iQ7, Hydrastar, and Dexter ranges.

Why Choose the LoadForce TA300?
The LoadForce TA300 is an excellent upgrade over older Trojan AU and Trigg A200 calipers.
Rather than using a phenolic (plastic) piston that can swell over time, the TA300 features a billet stainless steel piston for improved reliability and smoother brake operation.
The upgraded stainless steel slide tubes further improve durability, making this caliper a popular choice for trailers regularly exposed to wet and coastal conditions.
