Drilled/Slotted Brake Rotors

Mazdatrix Home Page Click part number for price View Cart


Brake pads fade when the temperature of the material allows gases to "boil" out and create a layer separating the pad from the brake rotor. The holes and slots in these rotors allow the layer to escape thereby keeping the pad in contact with the rotor. The rotor will also run cooler, which helps keep the pads cooler while also reducing the risk of fluid boiling. Note: Pads WILL still fade, and fluid WILL boil if the brakes are used beyond their SAFE capacity. Additionally, drilled rotors tend to crack around the holes due to heat expansion and contraction. Therefore there is no warranty on these parts, and the customer assumes all responsibility for their safe use. All prices are per rotor.

Note: 79-85 front rotors do not come with bearings or races. 84-85 GSLSE use press in wheel studs in the front which are not included with the rotors.
