In a disc brake system, which elements constitute the fixed part that does not rotate with the wheel?

Question

DentroTest · Accepted Answer

To answer correctly, we must distinguish between the two main parts of a braking system: the moving part and the fixed part. Moving Part: This is the disc, which is attached to the wheel hub and rotates at the same speed as the wheel. Fixed Part: These are the brake pads (housed in the caliper), which do not rotate. When braking, these clamp down on the disc creating friction to stop it. Important clarification: Although 'shoes' (zapatas) are technically the friction element for drum brakes and 'pads' (pastillas) are for disc brakes, the correct answer groups both terms ('Shoes or pads') referring to the fixed friction materials, as opposed to the rotating surfaces (drum or disc).
