FAQs

Q: Are calipers included?

A: Hydraulic calipers are available separately.

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.

Q: Can I get axles with this kit?

A: Yes. You can add ready-made axles or custom fabricated axles to your order. To get axles made to your specifications, please visit:

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: Can I use this for boat or marine trailers?

A: For boat and marine applications, we recommend our range of stainless steel brakes. You may reach out to our team for help regarding specific parts.
