Product Information

Sold Individually

Commonly referred to as a Brake Disc or a Brake Rotor, these components play a vital role in your braking system. When applying the brake pedal, this produces hydraulic fluid pressure which then transfers the pressure from the pedal through your braking system and into your brake calipers. The caliper pistons then apply pressure against your brake pads squeezing them inward against your brake rotors ultimately causing friction and stopping the vehicle. Brake rotors are a regular maintenance item which requires either servicing by means of machine work, or most commonly replacement when they become too thin, pulsate, glaze, or grind from worn-out brake pads. It's recommended to replace the brake pads and rotors at the same time.

• Pulsating
• Grinding
• Squeaking
• Glazing
• Hot spots
• A noticeable lip on the rotors outer edge
