All brake systems depend on the synchronized movement of specific parts needed to provide safe operation. Brakes systems are primarily hydraulic processes that utilize fluid held in the reservoir and throughout the brake lines that force the pads onto the rotor when pressure is applied at the foot pedal or when an automatic braking system is engaged. Automatic brake systems are typically standard equipment on newer vehicles, but many older models still use the traditional brake assemblies.
Both types of braking devices use fluid to ensure that all parts work properly.
