The floating-type calliper, also known as a floating calliper, is one of the most frequently used brake callipers in vehicles. A special feature here is that the brake calliper can be moved by means of guide bolts. This type of mounting is also referred to as floating mounting. When the brake is applied, the brake piston presses against the inner brake pad and presses this against the brake disc.

If the above-mentioned set of error symptoms is detected in connection with error code P0201 (Fig. 1), a possible cause may be a contact fault on the multi-connectors on the injection system harness.
