Definitions:
Disc Brakes
A type of brake system that uses calipers to squeeze pairs of pads against a disc or rotor to create friction, slowing the rotation of the wheels.
Drum Brakes
A type of brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part known as a drum.
Phenolic Plastic
A type of plastic made by polymerizing phenols and aldehydes, used in electrical and mechanical components due to its insulating and heat-resistant properties.
Caliper Pistons
That part of a disc brake caliper that applies pressure against the brake pad. Pistons are made of steel, plastic, or aluminum.
