Your braking system may not be rocket science, but it is getting closer by the day!
A simple braking system is not simple at all. It uses many components, all working together, to help you stop a very heavy, and sometimes very fast moving, vehicle as quickly as possible for turning, parking, and emergency stopping. Just think, all you have to do to get them to work together is push the brake pedal.
Most vehicles use either a disk brake or drum brake assembly at the wheels to stop. Below is an example of an electric trailer brake assembly. They all use pads or shoes to push against the revolving drum/rotor to stop the vehicle.
