What is the Brake Rotor/Disc about?

A brake rotor is a smooth metal disc linked to the wheel hub. Most new vehicles (1999 and above) come with rotors at each wheel. Older vehicles may have drums instead of rotors at the rear wheels . Brake rotors play a vital  part in the braking system. It is the friction between brake pads and rotors that make your car to slow down and stop. As the rotors begin to wear (become thin or warped), they are unable to dissipate the heat generated by the braking system. This will cause the brake fluid to boil and reduce the effectiveness of brake system greatly.

Bear  in mind:

Brake rotors are changed in pairs. If you choose front brake rotors, both front wheels will get new rotors. This service comes with brake pads. Unless brake pads were changed recently, pads must be changed while replacing the rotors.

How it is done:

  • Measure the thickness of brake rotors.
  • Remove and change rotors and pads.
  • Carry out a brake safety inspection.
  • Perform test drive.


It is a good to get the thickness of brake rotors measured annually. Your Auto-mechanic should measure the rotor thickness every time the brake pads are changed. Brake rotors usually last twice as long as brake pads, which usually means you need to change rotors every other brake service. If you drive the vehicle with worn-out brake pads for too long, you will destroy the rotors.

What common signs  indicate you may need to replace the Brake Rotor/Disc?

  • Vibration or pulsation while applying brakes.
  • Blue discoloration of rotor surface.
  • Grooves or hot spots in rotors.

How vital is this service?

All services linked with proper function of your brakes are very essential. In addition to safety issues, ignoring small repairs can quickly result in more serious (and more expensive) problems.
