What are Brake Discs?
The Brake Discs (also referred to as Disc Rotors) are the circular metal plates located behind your wheels, that the Brake Pads press against to stop your vehicle.
Your vehicles Braking System is engaged when you put your foot on the Brake pedal, the Brake fluid acts on the Brake Discs inside the caliper and they are forced against those discs.
This process is what slows the vehicle.
As the Plates and Discs are in constant contact, the Brake Discs/Disk Rotors can wear unevenly and cause problems, including your vehicle pulling in one direction when slowing down, or a strong vibration through the body of the vehicle.
This requires the Disks to either be machined or replaced based upon on their ‘minimum thickness’.
(R & L Automotive will measure this thickness before we choose /advise you what is needed)
What is brake disc machining?
Some mechanics will recommend machining your Brake Disks/Disk Rotors each time you change your Brake Pads.
There are two major factors to consider before you do machine brake discs:
- The condition of the Rotors inspected
- If the Rotors have been machined previously and how many times (as there are minimum Rotor thickness specifications from each manufacturer).
Braking is more effective the smoother the Brake Discs are, so when the new Brake Pads are fitted they should fit flush against Discs.
If you’ll be going below the ‘minimum standard’ for your vehicles Brake Discs/Disc Rotors, they should just be replaced, so you don’t compromise your general vehicle safety and braking system condition.
