Why do we machine the disc rotors when replacing the disc pads?
Modern vehicles today have better braking systems than vehicles of yesterday, but to achieve this the frictions applied are far greater and generate a lot more heat, causing disc rotor warping and bending. This is normally felt as a brake shudder or brake pedal pulsing. Excess noise can also be generated due to glazing of the disc rotors again caused by heat.
By machining the disc rotor surfaces at brake pad replacement time, you are ensuring that your brakes are back to “as new” condition and therefore more efficient and safer.
All rotors are measured before machining. If they are under minimum thickness we recommend replacement.
Don’t wash your wheels just after driving your car as the cold water hitting the hot brake parts causes disc rotor distortion, again leading to shudders and pulsing.
Avoid excessive and heavy braking, as this causes excessive heat.
Avoid driving through large quantities of water when your disc rotors are hot.
