Brake Disc Left Or Right

A handed brake disc rotor is designed specifically for the left or right side of the vehicle and may also differ between front and rear axle positions. These directional discs feature vane patterns, grooves or drilling that must rotate in the correct direction to ensure optimal cooling, reduced brake fade and improved stopping performance. At A-Z Motor Factors Halifax, we supply high-quality left-hand and right-hand brake discs for all makes and models, with OE-matching accuracy and fast UK delivery.

Unlike standard brake discs, directional discs are engineered with internal and external patterns that only work correctly on a specific side of the vehicle. These features include:

• Angled cooling vanes

• Spiral or curved vents

• Directional grooves

• Drilled patterns

• Handed rotation design

This improves airflow, braking efficiency and heat control, meaning the disc must be installed on the correct side.

Left-hand (LH) = Driver side (UK)
Right-hand (RH) = Passenger side (UK)

Many performance or vented systems rely on directional discs to maintain consistent braking and prevent overheating.

Brake discs differ between:

• Front axle: usually larger, vented for heavy braking

• Rear axle: may be solid, smaller, or built for parking brake systems

Directional discs require exact positioning:

• Front Left (FL)

• Front Right (FR)

• Rear Left (RL)

• Rear Right (RR)

Our VRM lookup tool ensures you receive the correct handed disc for your vehicle.

Replace your directional disc if you notice:

• Vibration or judder when braking

• Cracks, heat spots or heavy corrosion

• Grooves or scoring on the disc face

• Pulling to one side under braking

• Noticeable brake fade

• MOT advisory for brake imbalance

Always replace discs in pairs — left and right together — for balanced braking.
