Understanding Jaguar Mk2 Brake Pads and Beyond
When it comes to maintaining the stopping power of your cherished classic Jaguar, selecting the right brake pads is paramount. For owners of the iconic Mk2 Saloon, produced between 1959 and 1969, understanding the available options can significantly impact both performance and longevity. This guide delves into the types of brake pads commonly used and recommended for the Mk2 and its contemporaries, offering insights into upgrades and essential components.
Brake Pad Evolution: From Standard to Performance
The braking systems of classic Jaguars, while effective for their era, have seen considerable advancements. Initially, vehicles like the Mk2 Saloon would have been fitted with standard organic or semi-metallic brake pads. However, the automotive aftermarket has responded to the demands of enthusiasts seeking improved performance, durability, and a cleaner aesthetic. This is where options like the "Green Stuff" Kevlar brake pads come into play.
The 'Green Stuff' Advantage for Classic Jaguars
A standout option for the Jaguar Mk2 and several other classic models, including the Mk10 3.8, XK150, Mk9, and Mk1, are the Green Stuff Kevlar brake pads. These are not your average brake pads; they represent an award-winning upgrade designed for both regular road use and spirited driving. Here's why they are a popular choice:
- High Friction Stopping Power: Expect a significant improvement, with up to 20% more grip compared to standard pads. This translates to shorter stopping distances and a more confident driving experience.
- Reduced Dust: A common complaint with older braking systems is the excessive black dust that accumulates on wheels. Green Stuff pads minimise this, with surface carbonisation only occurring at temperatures of 900°F and above, which is well beyond typical road usage.
- Improved Disc Life: Utilising space-age aramid fibres and containing no ferrous content, these pads are gentler on your brake discs. This means reduced disc wear over time, potentially saving you money on replacement parts.
- Instant Response: Unlike some pads that require a warm-up period, Green Stuff pads offer instant response from cold, ensuring reliable braking from the moment you set off.
- Pad Lifetime: A common lifespan for these pads under normal road use is between 10,000 to 20,000 miles, offering a good balance of performance and longevity.
- Versatility: They are ideal for all classic cars, whether used for normal road driving or occasional competition use.
The Green Stuff Kevlar brake pads are specifically mentioned as fitting the Mk2 Saloon, along with the Mk10 3.8, XK150, Mk9 Rear, and Mk1 models, making them a versatile upgrade for a range of classic Jaguars.
Essential Braking System Components for the Mk2
Beyond the pads themselves, a healthy braking system relies on several other critical components. For the Jaguar Mk2 and similar models, these include:
Stainless Steel Braided Rear Brake Hoses
Replacing standard rubber hoses with stainless steel braided ones offers several benefits:
- Improved Brake Feel: They provide a firmer, more direct connection between the brake pedal and the braking mechanism.
- Enhanced Durability: Stainless steel braiding offers superior resistance to abrasion and environmental factors compared to rubber, leading to a longer service life.
- Compatibility: These hoses are also suitable for the Mk1 Saloon when fitted with disc brakes.
Handbrake Components
The handbrake, a crucial safety feature, also has several parts that may require attention:
- Ratchet Friction Spring: Essential for self-adjusting handbrake systems.
- Hand Brake Retraction Fork: A key component in the handbrake mechanism, also fitted to models like the XK150 (late), Mk2, Mk9, Mk10 3.8, and E Type 3.8.
- Genuine Handbrake Return Spring: A genuine Jaguar part ensuring the proper return function of the handbrake lever.
Brake Fluid Reservoir and Related Parts
Maintaining the brake fluid system is vital:
- Jaguar Brake Fluid Reservoir Bottle: Available as a bottle only or as an assembly complete with cap and sender unit. This component is designed for late XK150, Mk2 Saloon and Daimler V8, S Type (1960s), and Mk9 models.
- Jaguar Brake Fluid Reservoir Cap and Sender Unit: A separate option for those needing just the cap and sender, compatible with the same range of vehicles as the reservoir bottle.
Cylinder and Disc Components
The heart of the braking action involves cylinders and discs:
- Front Brake Cylinder and Piston Assembly: A brand-new assembly, complete with seals, designed for the XK150 (square pad type).
- Front Brake Disc: Available for the Mk2 Saloon and early S-Type (Dunlop Brakes), sold individually. These are also compatible with the Series 1 E Type.
Warning Light Switch
Don't overlook the small but important parts like the Handbrake Warning Light Switch, ensuring your dashboard indicators function correctly.
Choosing the Right Brake Pads: A Summary
For your Jaguar Mk2, the Green Stuff Kevlar brake pads offer a compelling upgrade path, providing enhanced stopping power, reduced dust, and better disc life. However, it's always wise to consult with a specialist or refer to your vehicle's specific workshop manual to ensure compatibility and the best fit for your driving needs.
