Triumph GT6 Brakes
The GT6's combination of lightweight construction and powerful 6-cylinder engine demands a brake system that matches its sporting character. Whether you're maintaining original components or upgrading to modern performance standards, we stock everything needed to keep your GT6 stopping safely and effectively.
What brake system was fitted to the GT6?
The GT6 received different brake specifications across its production run, with significant improvements introduced on later models. Early GT6 Mk1 and Mk2 models (1966-72) used 2-pot front brake calipers with solid brake discs, providing adequate stopping power for the original specification.
GT6 Mk3 models from chassis KE12389 and KF12390 (approximately August 1972 onwards) received upgraded brake systems with 16PB calipers featuring 3/16" brake pad retaining pins. These later calipers offered improved brake pad area and better heat dissipation characteristics.
The brake disc diameter on GT6 models typically measured 9.3" to 9.75", though some competition-prepared cars received larger 10.25" discs with special mounting brackets. Rear brakes remained drum-based throughout production, using 9" brake drums with appropriate wheel cylinders.
Are there uprated brake options for the GT6?
Modern brake upgrades transform the GT6's stopping performance and maintain authentic appearance. Four-pot caliper conversion kits provide dramatically improved brake pad area and heat management compared to original 2-pot systems.
These uprated systems typically feature vented brake discs that run significantly cooler than solid discs, reducing brake fade during spirited driving. The increased brake pad contact area delivers shorter stopping distances and improved pedal feel.
BCC and other manufacturers offer complete bolt-on conversion kits that require no permanent modification to the vehicle. These systems use aerospace-grade aluminium calipers with stainless steel pistons and modern sealing technology for enhanced durability and performance.
How do I identify my GT6's brake components?
Chassis number identification determines the correct brake components for your GT6. Early models to approximately KE12388 and KF12388 used the earlier brake pad type without the 3/16" retaining pins.
Late GT6 Mk3 models from KE12389 and KF12390 onwards require brake pads with 3/16" diameter pins, often identified as 16PB caliper applications. These later brake pads offer improved retention and reduced brake noise.
Brake disc identification involves measuring the diameter and thickness, with most GT6 models using 9.75" solid discs. Competition or modified cars may have different specifications, so physical measurement confirms the correct replacement parts.
What maintenance does the GT6 brake system require?
Regular brake system maintenance ensures optimal performance from your GT6's braking components. Brake fluid changes every two years to prevent internal corrosion and maintain proper hydraulic pressure throughout the system.
Brake pad inspection should occur every 6,000 miles or annually, with particular attention to pad thickness and wear patterns. Uneven wear may indicate caliper problems or brake disc warping that requires attention.
Caliper rebuild intervals depend on usage and storage conditions, but typically every 5-7 years keeps the system operating properly. Modern seal kits use improved materials that offer better durability than original components.
