Allocation PR-No./Brakes
The brake system installed in a vehicle is documented on the vehicle data sticker via the relevant PR number.
The vehicle data label can be found in the spare wheel well as well as in the Maintenance booklet.
The following tables show the break down of the affected PR numbers. They are important for the brake disc/brake caliper/brake drum combinations.
