Hi-Q Front Brake Rotor 328mm — HQD2748

This Hi-Q HQD2748 (RDA8002) is a front disc brake rotor with a 328mm outside diameter, made by Sangsin Brake and engineered to resist heat and hold its shape for smooth, consistent braking.

Sold individually: this listing is for one rotor.

The rotor is the disc your brake pads clamp onto — it takes the heat of every stop and turns your car's momentum into heat that it then has to shed. A rotor's whole job is to stay flat and true while it does that, because a rotor that warps or loses its shape under heat is what you feel as brake shudder: the steering wheel or the pedal pulsing as you slow down.

Hi-Q rotors are built for that:

• Smooth braking with less vibration: a true, flat rotor gives even pad contact, so the brakes pull up smoothly instead of shuddering.
• High resistance to thermal stress and deformation: the rotor resists the heat stress that causes warping, and holds its dimensions and flatness in service.
• Performance under high heat: it keeps working under the higher temperatures of hard or repeated braking, such as towing, hills or heavy stop-start driving, where a rotor that cannot shed and withstand heat starts to fade and distort.

Fitting

• Replace rotors as an axle pair — order two so both sides are done together and braking is even side to side.
• Clean the protective coating off the braking surface before fitting, and make sure the hub face is clean and free of rust — a speck of rust or dirt behind the rotor is enough to make a new rotor run out and pulse.
• Bed the new rotors and pads in gently for the first few hundred kilometres and avoid hard stops until they are seated.
