You will need a flashlight to get the job done.
1. We prepare the car for work (see "Preparing the car for maintenance and repair").
2. Using a slotted screwdriver, remove the rubber plug of the inspection hole in the rear wheel brake support shield.
3. We illuminate the viewing hole with a flashlight.
4. If the thickness of the lining of the brake pad A is less than 1.5 mm, then the pads must be replaced.
Install the plug in place.
