Turbo Grooved Brake Discs (Pair) - GD1338

The EBC Turbo Grooved Brake Discs, model number GD1338, are a pair of high-performance rear brake rotors designed for a range of performance vehicles. They are engineered to improve braking efficiency, particularly for spirited driving and high-demand situations. The signature feature is a pattern of wide aperture slots and machined dimples on the braking surface.

Design and Performance

The unique design of the EBC Turbo Groove Discs provides several key advantages to enhance braking performance and longevity.

• Superior Cooling: The wide, curved slots are engineered to pull cool air across the rotor surface, significantly reducing braking temperatures. This helps to prevent brake fade during heavy use and can lower operating temperatures by as much as 100 degrees Celsius.

• Debris and Gas Removal: The grooves actively clean the pad surface, removing dirt, water, and debris. They also vent hot gases that can build up between the pad and disc, ensuring a firm and responsive pedal feel.

• Enhanced Durability: EBC uses dimple drilling instead of through-drilling. This provides the benefits of pad degassing without the risk of stress cracks that can develop around fully drilled holes, a common point of failure in high-stress applications.

• Consistent Pad Wear: The slotted design helps to maintain a flat and parallel pad surface over the life of the pads. This ensures optimal contact and consistent braking performance from new pads to worn ones.

Construction and Finish

EBC manufactures these discs from high-quality grey iron castings, which are then CNC-machined to precise tolerances. To ensure lasting quality and appearance, the non-braking surfaces of the discs are protected by a corrosion-resistant silver Geomet coating, which matches the finish of many original equipment rotor hubs.
