Trojan Disc Brake Calipers – Reliable Braking for Light Trailers

Trojan Disc Brake Calipers – Reliable Braking for Light Trailers offers a full range of disc brake calipers to suit light trailer applications. Engineered for durability, safety, and performance, these calipers provide consistent stopping power across a variety of setups. Whether you need cast iron strength, stainless steel corrosion resistance, or a retro fit replacement, Trojan has the right solution.

Cast Iron Calipers – Hydraulic Type

  • Manufactured from SG cast iron

  • Electro zinc plated for corrosion protection

  • Fitted with a Phenolic piston (non-rusting, high-strength material)

  • Brass slide pins and bleed screws with stainless steel fittings

  • Stopping capacity:

    • 1500kg per pair (with 225mm dia rotors)

    • 2000kg per pair (with 275mm dia rotors)

Stainless Steel Calipers – Hydraulic Type

  • Cast in high-grade stainless steel for complete corrosion resistance

  • Ideal for boat trailers and marine use

  • Equipped with Phenolic pistons, brass, and stainless fittings

  • Brake pads include stainless steel backing plates to prevent lining separation from corrosion

  • Same stopping capacity and specifications as cast iron versions

Retro Fit Calipers – Hydraulic Type

  • Available in cast iron only

  • Direct replacement for discontinued early MK2 Trojan hydraulic calipers

  • Only difference is the mounting bolt position

  • All other specifications match current models
