The Ultimate Endurance Caliper: PB6 Water-Cooled Rally System

When air cooling is no longer enough, active thermal management is the only answer. The PB6 Water-Cooled caliper is the definitive braking solution for professional endurance, rally raid, and drift teams where extreme, sustained heat is the primary cause of failure.

Building on the battle-tested PB6 forged caliper, this version incorporates an integrated liquid cooling circuit. By actively circulating fluid through the caliper body, this system provides the ultimate defense against brake fade and fluid boil, ensuring consistent, powerful, and reliable braking performance from the first lap to the last, even in the most punishing race environments. Each kit is a fully bespoke, custom-engineered solution for your specific race application.

Bespoke Fitment & Ordering Process

Step 1: Technical Consultation

Initiate your order by contacting our motorsports engineering team. We will conduct a detailed consultation to understand your vehicle, competition class, and specific performance requirements, including the integration of your cooling system.

Step 2: Submit Specifications

For Factory Knuckles: Provide vehicle year, make, model, and detailed wheel specifications.

For Modified Knuckles: Provide detailed measurements, technical drawings (CAD files preferred), or high-resolution photos of the custom knuckle assembly.

Step 3: Engineering & Approval

Our engineers will design the bespoke mounting hardware for your application. We will provide you with the final design specifications and production timeline for your approval before manufacturing begins.

Frequently Asked Questions

How does the water-cooling system work?
The caliper body features integrated channels with an inlet and outlet port. These are designed to be plumbed into an external pump and radiator system (not included). Circulating coolant through the caliper actively extracts heat, providing superior thermal management far beyond what air cooling alone can achieve.
Who needs a water-cooled brake system?
This is a highly specialized, professional-grade solution for the most extreme forms of motorsport where brake temperatures are the primary limiting factor—such as endurance racing, rally raid, and professional drifting.
What information do I need for a custom order?
For a vehicle using **factory steering knuckles**, we require the year/make/model and detailed wheel specs. For a **fully custom or modified knuckle**, we require technical drawings, CAD models, or precise measurements of the mounting points to engineer a perfect, bolt-on solution.
Notice

Brake Kit Purchase Notice


  • Custom‑made products cannot be returned unless there is a genuine quality defect.
  • Spacer requirements vary depending on wheel design; we assist with fitment, but spacer‑related issues do not qualify for returns.

1. Disclaimer

  1. Please provide vehicle make, model year, VIN, and wheel size before ordering TTSPORT products.
  2. Confirm wheel measurements and submit photos as requested — TTSPORT is not liable for issues arising from incorrect specs.
  3. All products are inspected before shipping. Inspect upon delivery and report quality issues within 24 hours.

2. Initial Break‑In Procedure

  1. In a safe area, brake from 60 km/h to 10 km/h with moderate pressure—repeat 10 times.
  2. Drive 500–1,000 km with light to moderate usage before full braking performance. Avoid aggressive stops.
  3. Our high‑carbon steel discs have grooved, color‑treated surfaces to help quick bedding and resist corrosion.

3. Product Warranty

  • Calipers: 1‑year warranty on defects. Lifetime maintenance available (parts charged).
  • Discs & Hoses: 90‑day warranty for defects. Expected lifespan: 40,000–60,000 km.
  • Brake Pads: 90‑day coverage. Typical lifespan: 20,000–40,000 km.
  • Custom Hats/Brackets: Fit guaranteed; no warranty post-installation.

4. Usage & Maintenance

  1. Do not wash immediately after hard braking to prevent rotor warpage.
  2. Allow extra stopping distance when driving in wet conditions.
  3. If you experience unusual noise or vibration, consult your installer immediately.

Recommended service intervals:

  • Replace rotors when wear exceeds 3 mm.
  • Front pads: every 30,000 km.
  • Rear pads: every 50,000–60,000 km.
  • Brake fluid: every 40,000 km or every 2 years.
