Mechanical Brake Caliper With Pull Forward Action For Tophat Hubs

The Trojan Mechanical Brake Caliper with Pull Forward Action is a purpose-built braking solution designed exclusively for Tophat hubs. This forward-pull mechanism engages the brake pads with rapid, controlled precision, delivering reliable stopping power exactly when you need it. Built for durability and consistent performance, it’s an ideal upgrade or replacement component for specialized hub configurations where precision and fitment matter most.

Why this caliper stands out

• Forward-pull action for fast, confident braking. The pull-forward design reduces the amount of lever travel required to engage the pads, giving you immediate feedback and predictable braking response.
• Exclusive compatibility with Tophat hubs. Engineered to integrate seamlessly with Tophat hub systems, ensuring a secure fit and reliable operation without adapters or guesswork.
• Robust, purpose-built hardware kit. The package includes the essential installation hardware visible in the image: mounting bolts, washers, and spacers, so you’re ready to install with minimal downtime.
• Precise fitment specs you can trust. Mounting bolt threads are 7/16–20 TPI UNF, a specification chosen to balance strength and ease of service, so you can torque with confidence and maintain long-term reliability.
• Durable construction with smooth operation. The caliper housing and moving components are designed for repeated braking cycles, with springs and a guided contact surface that promote consistent pad alignment and return.

Key features and benefits

Designed by Trojan, this caliper emphasizes real-world performance over generic specs. The visible dual springs provide stable pad retraction after braking, helping minimize pad drag and heat buildup on long descents or frequent stop-and-go situations. The machined surfaces and solid housing reduce play and improve modulation, so you can apply precise amounts of braking force in delicate turns or abrupt stops alike.

Who benefits most

Shop owners, restoration specialists, and enthusiasts working with Tophat hub-based systems will appreciate a component that fits directly and performs consistently. It’s particularly well-suited for builds where precision braking and reliable fitment are critical—whether upgrading aging hardware, restoring a classic setup, or configuring a dedicated vehicle for demanding applications.

Use cases and real-world scenarios

• Upgrading a vintage or specialty vehicle that uses Tophat hubs and requires a forward-pull braking solution.
• Replacing a worn caliper when you need an exact fit with 7/16-20 UNF mounting threads to match existing hardware.
• Maintaining consistent pad seating and quick engagement in high-frequency braking environments, such as urban driving with frequent stops or performance-focused setups.
