Premium Brake Drum with Black Zinc Coating
Upgrade your braking performance with these precision-manufactured brake drum designed specifically for classic British cars. Made from high-quality GG20 grey cast iron, these drums provide excellent heat dissipation, consistent friction characteristics, and long service life making them an ideal material for reliable braking performance.
Each drum is precision machined to strict tolerances, ensuring that runout never exceeds 30µm (0.03mm). This level of accuracy helps deliver smoother braking, reduces the chance of pedal pulsation, and promotes even brake shoe wear.
A durable black zinc coating protects the drum and outer edges from corrosion while providing a clean, finished appearance behind your wheels. The coating on the braking surface naturally clears during the first few stops, leaving the protected areas resistant to rust.
