FAQs

Q: What braking system is needed to operate the hydraulic disc brakes?

A: This set can be used with a hydraulic override coupling fitted to the trailer drawbar. You may also opt to install an electric-over-hydraulic kit if you prefer to have more braking options, and if you want the ability to control the brake from inside the towing vehicle.

Our HydroBrake EOH actuator and controller kits are excellent options. Please visit this page to learn more:

Q: Does the axle include brake pads?

A: Yes. The cast iron calipers are supplied complete with brake pads fitted. Replacement pads are available separately.

Q: What are the advantages of using box section beams for axles?

A: Box section beams (hollow tube axles) offer significant weight savings without compromising strength for most applications. Their lighter construction allows for increased payload capacity, easier handling during installation, and faster fabrication turnaround. They also allow for easy customisation, making them a flexible choice for trailer builders.

Q: What is Geomet surface treatment?

A: Geomet is a water-based zinc-aluminium flake coating, typically used in truck and car brakes. It provides long-lasting protection against rust and corrosion, is highly heat-resistant so it won’t burn off under braking, and is environmentally friendly as it contains no hexavalent chrome or heavy metals. It works through physical barrier protection, galvanic action (where zinc corrodes before steel), and passivation—forming a stable layer that slows further oxidation. This makes it ideal for trailer brake rotors, delivering durability, consistent performance, and reduced maintenance.

Q: What are the benefits of cast iron hubs?

A: Cast iron hubs are a popular choice for trailer braking systems due to their combination of strength, thermal performance, and cost-effectiveness. Here are the key benefits:

High Strength and Load Capacity: Cast iron has excellent compressive strength, making it well-suited for supporting heavy loads without deforming. This makes it ideal for medium- to heavy-duty trailers.

Superior Heat Dissipation: During braking, friction generates heat. Cast iron naturally dissipates heat efficiently, helping to maintain braking performance and reduce the risk of brake fade over time.

Durability and Wear Resistance: Cast iron is highly resistant to wear and abrasion, which contributes to a longer service life—especially important in braking components that experience repeated stress.

Stable Performance Under Load: Its rigidity and dimensional stability under high temperatures ensure consistent braking performance, even during prolonged use.
