If your brake pads are worn thin then the braking efficiency may be severely reduced. This can not only cause expensive rotor damage, but is dangerous.
Most brake pads should last between 30,000 and 65,000 kilometres, depending on your driving conditions. Therefore, inspect your disc brake pads regularly and replace if needed with quality brake pads available at Supercheap Auto.
What You'll Need
- Floor jack and stands
- Outside micrometer
Tips and warnings
- Brake pads are designed with indicators that emit a scraping sound when worn out. If you hear this sound when applying your brakes, they need replacing.
Step 1 – Check The Caliper
Make sure the caliper is cool to touch, then grasp it and make sure it is mounted securely.
Brake components will be hot if the vehicle has been driven recently
Step 2 – Check The Brake Pads
Check the linings on the brake pads – if they are too worn they may need to be replaced.
The easiest way to estimate the wear is to look at the thickness of the backing pad, and if the thickness of the remaining brake lining surface is the same as (or less than) that on the backing plate the pad should be replaced.
If the linings have worn so much that they are running on the pads backing plates, the discs may have to be machined.
Step 3 – Check The Rotor
Check the visible part of the rotor for rust, scoring or uneven wear.
Check the workshop manual specifications of this rotor and measure its thickness with an outside micrometer. If the reading is outside the manufacturer’s specifications you might need to have it checked out by an expert.
You will need to repeat this procedure for each of other three wheels.
