What happens to the brake shoe and drum when the pedal is pressed?

The brake shoes are inside the drum, which is turning along with your wheel. When you press the pedal, it pushes fluid through the brake line, and that fluid forces the shoes outward and they push on the inside of the drum, which slows it down, and thus slows down your car.

Function and operation of rotor brake system?
With a rotor braking system there is a curved brace with lining that fits inside the wall of a round drum. When the brake pedal is pressed, hydraulic fluid goes through the line and makes the brace with the lining press against the side of the drum until the drum stops turning.
What does a wheel cylinder do?
Operates the brakes when the pedal is pressed. The pedal pushes the master cylinder, this pushes brake fluid down the brake lines, the fluid pushes the piston(s) in the wheel cylinder, the pistons push the pads or shoes onto the drum or rotor which is attached to the wheel.
What happens when a drum vibrates?
Blow the old brake dust out of the drum.
Why does the brake pedal pulse on a 1999 Honda CRV?

What would cause right rear brake to lock up by just tapping the brake pedal?
most likely if you have drum brakes. the shoe has came off the metal mount, and lodged itself in the drum. get new brake shoes. but have fun getting the drum off!!!!!!
Why would one rear wheel lock up on a truck then release once you pressed the brake pedal?
Without knowing what kind of truck/car, I would believe that the best thing to do is take off the wheel and drum and have a look. Could be the springs, could be a brake fluid leak. Does the brake light come on? Do you have ABS? Could be a stuck parking brake cable. Is it drum or disc? If disc, could be a stuck piston in the caliper. Hope this helps.
How do drum brakes work?
the brake shoes are expanded, and rub against the inside of the drum when the brakes are applied. the shoes are pushed apart by a brake cylinder that is operated by hydrolic pressure sent through the brake lines from the master cylinder when you step on the brake pedal. the brake fluid is what is forced througt the brake lines to the wheel cylinders. springs are attached to the shoes ,and pull them back away from the drums when the pedal is released. it is spring action against hydrolic pressure .
How do hydrauli brakes work in a car?
hydraulic brakes work on hydraulic fluid the system is filled with fluid, all air is bled out of the system so only fluid remains thru valves and other components the fluid is displaced when when the breake pedal is pressed on each wheel at the brakes are some moving parts ,on drum brakes these are brake shoes and cylanders on disk brakes these are brake pads and calipers when the fluid is displaced thru use of the pedal these parts are pushed out by the fluid that ahas no where else forcing the pads or shoes against the brake disk or drum when pedal is released the fluid goes back to reservoir releasing pressure on parts at wheel which releases brakes

What is the function of a drum brake?
A drum brake is a brake that uses friction caused by a set of shoes or pads that press against a rotating drum-shaped part called a brake drum. The term drum brake usually means a brake in which shoes press on the inner surface of the drum.
What are 5 parts of a drum brake system?
Brake drum: A rotating cylindrical component that provides a surface for brake shoe friction material to press against. Brake shoes: Curved metal components lined with friction material that press against the inside of the brake drum to create friction and slow down the vehicle. Wheel cylinder: A hydraulic component that pushes the brake shoes against the brake drum when the brake pedal is pressed. Brake adjuster: Mechanism that adjusts the position of the brake shoes as they wear down to maintain proper braking performance. Return springs: Springs that retract the brake shoes away from the drum when the brakes are not applied, allowing for free rotation of the wheel.
