Vehicle brakes are a complex system of levers, hydraulics, and friction that, when used properly, can quickly stop a vehicle's momentum and force. Brake repair, which applies to the entire braking system, is complex and requires the experience and experience of a licensed professional who can ensure that the brakes are properly repaired and ready for safe vehicle operation.
When the driver depresses the brake pedal, the master cylinder depresses oil and sends hydraulic pressure to the brake pads. When the brake pads come into contact with the rotor, they create enough friction to slow down the vehicle and eventually stop.
The most common car brake service is brake pad replacement. When the brake pads come into contact with the rotor, a squeak will be heard indicating that the brake pads need to be replaced. Worn brake pads can be a serious problem and require rotor replacement.
Most cars have a disc system connected to a wheel or axle that connects to the hydraulic system. The discs are usually made of cast iron and, together with the rotor and brake pads, create friction that slows down the car's tires.
The force used to stop the car is much greater than the force applied simply to apply the brake pedal. The hydraulic system is part of the braking system: it creates enough pressure to apply force to the brake discs, which creates friction to slow the car. Brake fluid is a type of hydraulic oil that transfers hydraulic force to the brake mechanism via hydraulic lines.
If the brake pedal does drop, it is usually an indicator of a low brake fluid level or a hydraulic system leak that needs to be repaired by the brake repair service. If a leak is found, it must be replaced before the vehicle is operated. If there is brake fluid, it must be refilled.
