Both wheels in bikes and all the wheels in cars.
Hydraulic car brake system diagram.
These friction pad rub against the rotating disc connected to the wheels of the vehicle and thus braking takes place.
The front brakes play a greater part in stopping the car than the rear ones because braking throws the car weight forward on to the front wheels.
Most modern cars have brakes on all four wheels operated by a hydraulic system the brakes may be disc type or drum type.
The diagram is shown below.
Working of a hydraulic braking system.
A hydraulic brake is an arrangement of braking mechanism which uses brake fluid typically containing glycol ethers or diethylene glycol to transfer pressure from the controlling mechanism to the braking mechanism.
When you depress the brake pedal in your car it is pushing on the piston in the brake s master cylinder.
A schematic illustrating the major components of a hydraulic disc brake system.
Double acting hydraulic brakes in double acting type of hydraulic brakes double or tandem master cylinder is used which provides higher brake force which can be transferred in double direction i e.

When the pedal is pressed piston pushes the pad by the pressure of the hydraulic fluid.
The disc brake is used in motor vehicles and cars etc.
