DBA’s unique directional wiper slot design limits the possibility of glazing your brake pads and allows for better ‘pad-bite’ under extreme braking. The wiper slot design constantly improves the disc pad friction face by wiping away the impurities, gases and resins from the friction material.

All DBA 4000 slotted series rotors feature the DBA directional wiper slot design, i.e. Left-handed and Right-handed directional slotting.

Features

• Unidirectional slotting (left and right) increases pad bite, reduces fade and delivers exceptional braking performance.
• Slots continually de-glaze the brake pads improving efficiency and reducing rotor scoring.
• Slots even out wear across the brake pad faces, increasing the effective contact area and extending rotor life.
• Slots help dissipate water when driving in poor weather, as well as pump away dust and dirt.
• Slotting also combats "out-gassing," where gas (from the pad bonding agents) can form a cushion between pad and rotor, greatly reducing braking power.
