Trojan offers a range of disc brake calipers to suit most applications.
These include types to operate both mechanical and hydraulic brakes. A stainless steel bolt-on park brake fitting is available to suit both the cast iron and stainless steel calipers. These are available in both forward pull and centre pull options.
The stainless steel calipers are supplied with brake pads that have stainless steel backing plates. All Trojan hydraulic calipers are fitted with Phenolic Pistons and all fittings are either stainless or brass. A Stainless Steel Caliper is available fitted with an integral mechanical park brake and all Stainless Calipers are supplied with brake pads that have a Stainless Steel backing plate. All calipers are sold per each.
Trojan offers a range of brake calipers which cover all light trailer applications. This allows the user to select the correct product for their particular application.
The following pages show descriptions of the products available plus part numbers. Shown below is a clarification of some of the terminology used.
CAST IRON CALIPERS - HYDRAULIC TYPE
These are cast in SG iron and are Electro Zinc Plated for protection against corrosion. These calipers are fitted with a Phenolic piston which is a high strength non-rusting material. Fittings, such as slide pins and bleed screws, are brass while other fittings are Stainless Steel. These calipers have a stopping capacity of 1500kg per pair when used with 225mm dia rotors and 2000kg with 275mm dia rotors.
STAINLESS STEEL CALIPERS - HYDRAULIC TYPE
These are cast in high-grade Stainless Steel and offer total protection against corrosion. Ideally suited for fitment to boat trailers. These calipers are also fitted with Phenolic pistons and other fittings are either brass or stainless steel. The brake pads supplied with these calipers have a stainless steel backing plate. Other specifications are the same as the above cast iron version.
STAINLESS STEEL CALIPERS - HYDRAULIC WITH INTEGRAL MECHANICAL PARK BRAKE
These calipers offer all the benefits of the standard stainless steel version described above but feature a built-in mechanical park brake. This park brake is required by law on trailers that have a GVW of 2500kg or more. The park brake has a reversible lever allowing either centre or forward pull operation.
RETROFIT CALIPERS - HYDRAULIC TYPE
These calipers are available in both cast iron and stainless steel and allow the direct replacement of the early MK2 Trojan calipers which are no longer available. The only difference between the current calipers and these conversion types is the position of the mounting bolts. All other specifications are the same.
3000KG CAPACITY HYDRAULIC BRAKE CALIPERS
These are available in either Plated Cast Iron or Stainless Steel plus a Stainless Version is available with an integral mechanical park brake. These calipers are imported from the USA together with the Disc Rotors. The calipers are of high quality and are fitted with stainless steel pistons and fittings. The mounting plate supplied allows the direct conversion from 12” dia electric drum brakes, as fitted to most imported USA built trailers and caravans, to the more efficient hydraulic disc brakes.
CABLE-OPERATED CALIPERS - MECHANICAL TYPE
These calipers are cast in SG iron and are Electro Zinc Plated for protection against corrosion. All fittings are either Stainless Steel or brass. The mountings are the same as the hydraulic versions. Two types of these calipers are available forward pulling, where the cables are routed directly from the operating coupling to the calipers, and centre pull where the cables are routed down the centre of the chassis and through a cable guide mounted on the axle. These mechanical calipers can be used for primary braking or as a park brake only. These calipers are rated at 1250kg per pair with 225mm dia rotors.
