Hydraulic Fluid
A piston on each end of the wheel cylinder pushes outward when the brakes are applied. This pushes the brake shoes against the brake drum and stops the vehicle. The pistons are forced out by the pressure of the brake fluid inside the wheel cylinder when you apply the brakes.

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.

As you press the brake pedal it pushes a rod inside the master cylinder that has seals on it which in turn forces brake fluid through the lines dowm to the wheels. This pushes out pistons in the calipers & wheel cylinders which have friction material attached to them (brake pads & brake shoes) against metal surfaces (rotors & drums) and slows the vehicle down. This is a very simpified explaination.
Brake booster pushrod
The correct answer is NOBUTI have seen systems with two unrelated problems have this happen. By forcing back the pistons in the caliper pushes the brake pedal up so the brake lights go out. The second problem is related to why the pedal does not return correctly:Master cylinder damageWeak or broken return springFaulty brake booster.And so on
It is inside the rear brake drums. It is the part that pushes the brake shoes out against the drum.It is inside the rear brake drums. It is the part that pushes the brake shoes out against the drum.
The main inside the engine pistons are made of aluminum or in some heavy diesels steel Clutch cylinder pistons can be made of plastic Brake pistons can be made of all three
the master cylinder is designed so that when the brakes are applied, the pistons (primary and secondary) closes the compensating port and opens intake port. this allows brake pressure to be formed in brake system to apply brakes and allows brake fluid to fill behind pistons (through intake ports) when you release the brakes, the primary and secondary piston springs push their pistons (inside the master cylinder) to its rest position, faster than fluid can fill the chambers. this causes the brake fluid to flow past the piston cups (this happens when the rubber cup flexes foward) as the pistons pass the compensating port, brake fluid is allowed to return to the master cylinder reservoir. the intake and compensating ports act as a breather for the master cylinder. hope this answers your queston :)
Requires a tool that not only pushes in the caliper but also rotates it as it goes in.
