It depends on what your needs are. If you are driving you don't need parking brakes, when you are parked your "park" gear should keep you in place but that's not always the case....
False
Yes, a parking brake system is required regardless of the functionality of the service brakes. The parking brake acts as an additional safety measure to secure the vehicle and prevent unintended movement when it is parked. It is a separate system from the service brakes and must be functional and in good working condition.
The law in the UK states that there should be two independent braking systems actually it is not a parking brake but an emergency brake
A parking brake system is not required if your service brakes are fully self-locking. Air brake systems (on semis, for instance) hold the brakes open only when air is supplied. If you blow the air the brakes lock under spring pressure.
Quick Service brakes and parking brakes.
The handbrake is only used for parking.
A is false. You have to have a parking brake. B is true, the parking brake has to be able to hold the vehicle on an incline. C can't be, as you have to have a parking brake.
In the UK the parking brake is called the handbrake, a motor vehicle must, by law, have at least two independent ways of applying the brakes. This is normally achieved on a car by having the foot brake hydraulically or, rarely, pneumatically operated and the hand brake cable operated.Added: (in the US) you must also have an operational parking (or hand) brake.In Canada, at least, (and I strongly suspect in USA and Australia) that is wrong. You DO require a parking brake as an emergency standby. The point is your regular brakes depend on hydraulic fluid and rubber seals, while the parking or emergency brake depends on cables. -A totally separate system.You also need the parking brake when parking the vehicle on an incline. The transmission park pawl may break causing the vehicle to roll off if you have no parking brake.
It is a mechanical means of holding the vehicle from moving. The parking brake system is separate from the hydraulic service brakes.
Parking brake? Service brakes? Pedal dropping? Bad Master cylinder? ABS Module?
It if false that is the service brakes fail to apply the parking brake in one motion. It should pumped.
The parking brake on most vehicles uses a cable to operate part of the service brake to prevent the vehicle from moving while parked. In some instances the parking brake cable can stretch/break/freeze and not allow the cable to engage the service brake component (shoe or caliper).Mostly if the parking brake does not work, you can drive the vehicle normally and the brakes work fine. Possibly a parking brake may be partially engaged causing the shoe or pad of one or two wheels to be in contact with the rotor or drum causing drag.
