The Triumph TR6, a beloved classic British sports car, is renowned for its engaging driving experience, from the distinctive straight-six exhaust note to its agile handling. For owners looking to elevate this already enjoyable machine, an upgrade to the braking system can offer a significant improvement in both performance and safety. Recently, Wilwood Disc Brakes showcased their newly designed big disc brake kit, specifically fitted to the front of a 1974 Triumph TR6. This enhancement not only modernises the classic but also provides a crucial boost to its stopping capabilities, making it an even more rewarding car to drive with confidence.
Understanding the Triumph TR6 Braking System
The original braking system on the Triumph TR6, while adequate for its time, can feel somewhat dated when compared to modern standards. As these cars are often used for spirited driving, rallies, or simply enjoyed on winding country roads, the demand placed on the brakes can be considerable. Over time, wear and tear can also diminish the effectiveness of the original components. This is where aftermarket upgrades, such as a big brake kit, become an attractive proposition for enthusiasts seeking to restore or improve their vehicle's performance.
The Wilwood Forged Dynalite Big Brake Kit
The focus of this particular upgrade is the Wilwood Forged Dynalite big brake kit. This comprehensive package is designed as a direct, easy bolt-on conversion for several classic Triumph models. The specific kit highlighted was installed on a 1974 TR6, demonstrating its applicability to the later production models. Importantly, this kit is also compatible with the 1967-68 Triumph TR5/TR250, and the 1965-68 TR4A, making it a versatile option for a range of TR enthusiasts.
Key Features and Components
The Wilwood Forged Dynalite kit for the Triumph TR6 typically includes:
- Rotors: High-quality 11.00" two-piece rotors are a significant upgrade in size over the original equipment. These are available in either a plain face finish for a classic look or a drilled and slotted design to aid in heat dissipation and pad cleaning, leading to more consistent braking performance, especially under heavy use.
- Calipers: The Dynalite calipers are forged for superior strength and rigidity, providing a firm pedal feel. They are designed to offer increased piston area, which translates to greater clamping force on the rotors. Wilwood offers a wide selection of 24 caliper colors, allowing owners to customise the aesthetic of their braking system to match their vehicle's style.
- Brackets and Hardware: The kit includes all necessary mounting brackets and hardware for a straightforward installation, ensuring that the new components integrate seamlessly with the existing suspension and steering geometry.
- Pad Selection: While not always explicitly detailed in a general overview, these kits are designed to accommodate a variety of brake pad compounds, allowing owners to tailor the braking characteristics to their specific driving needs, from daily driving to track use.
Benefits of a Big Brake Kit Upgrade
Upgrading to a big brake kit offers several compelling advantages for a classic car like the Triumph TR6:
Improved Stopping Power
The most significant benefit is a substantial increase in stopping power. Larger rotors and calipers with more piston area mean more braking force can be applied, reducing stopping distances considerably. This is particularly noticeable during hard braking or in emergency situations, providing a greater sense of security.
Enhanced Heat Dissipation
Larger rotors, especially those with drilled or slotted designs, have a greater capacity to dissipate heat generated during braking. Overheating (brake fade) is a common issue with original braking systems when pushed hard. A big brake kit mitigates this, ensuring consistent performance even under prolonged demanding use.
Better Pedal Feel and Modulation
The increased rigidity of forged calipers and improved hydraulic balance often result in a firmer, more responsive brake pedal. This allows for finer control over braking pressure, enabling better modulation and a more precise feel for the driver.
Aesthetic Enhancement
Beyond performance, big brake kits can significantly enhance the visual appeal of a classic car. Visible through the wheels, the larger rotors and colourful calipers add a modern, performance-oriented look.
Compatibility with Other Upgrades
As mentioned, these kits are engineered to be fully compatible with the OE master cylinder output. This means that in many cases, the existing master cylinder can be retained, simplifying the conversion. Furthermore, a big brake kit is often a complementary upgrade to other modifications such as wider wheels, performance tyres, and suspension improvements, creating a more balanced and capable overall package.
Installation Considerations
The Wilwood Forged Dynalite big brake kit is designed for an easy bolt-on installation. However, as with any significant brake modification, it is recommended that the installation be carried out by a qualified mechanic or an experienced individual. Proper bleeding of the brake system is crucial for optimal performance and safety. The kit is manufactured in the USA and engineered specifically for these Triumph models, ensuring a high level of quality and fitment.
Triumph TR6 Brake Upgrade Options: A Comparison
While the Wilwood Dynalite kit is a popular choice, other options might exist for TR6 owners. Here's a general comparison of potential upgrade paths:
| Feature | Original System | Wilwood Dynalite Kit | Other Aftermarket Kits (General) |
|---|---|---|---|
| Rotor Size | Smaller (e.g., ~10") | Larger (e.g., 11.00") | Varies, often larger than original |
| Caliper Type | Often 2-piston | Forged Dynalite (multi-piston options available) | Varies, often multi-piston |
| Performance | Adequate for period | Significantly improved stopping power, fade resistance | Generally improved over original |
| Installation | Original fitment | Bolt-on conversion | Varies, some bolt-on, some may require modifications |
| Cost | Lower (for replacement parts) | Moderate to High | Moderate to High |
| Customisation | Limited | High (caliper colours) | Varies |
Frequently Asked Questions
Q1: Will the Wilwood Dynalite kit fit my Triumph TR6?
Yes, the Wilwood Forged Dynalite big brake kit is specifically engineered for the Triumph TR6, as well as the TR5/TR250 and TR4A models from the specified years.
Q2: Do I need to change my master cylinder?
Generally, these kits are designed to be fully compatible with the OE master cylinder output, meaning you may not need to upgrade it. However, it's always advisable to check the specific kit's requirements or consult with the supplier.
Q3: Can I install this kit myself?
The kit is designed for an easy bolt-on installation. If you have good mechanical experience and the right tools, DIY installation is possible. However, for optimal results and safety, professional installation by a qualified mechanic is recommended.
Q4: What are the advantages of drilled and slotted rotors?
Drilled and slotted rotors help to vent gases and moisture away from the braking surface and keep the pads clean. This improves cooling and provides more consistent braking performance, especially under demanding conditions, reducing the risk of brake fade.
Q5: How much does a big brake kit typically cost?
The cost can vary significantly depending on the brand, the number of pistons in the calipers, and the rotor size and type. Wilwood kits are generally considered a mid-to-high range option, reflecting their quality and engineering.
Conclusion
