DIFFERENCE BETWEEN FOOT BRAKE AND HAND BRAKE

Motorists around the world know  how to use foot brake and hand brake, even non-motorists are aware of their operation but how many are actually aware of the working mechanisms of braking using the pedal and the handbrake? very few, i guess. So without wasting much time let's break down the difference


Foot Brake and Handbrake: The Real Difference

If you have always been looking for the answer to- “when should I use handbrake and foot brake,” then delve deeper into their mechanisms and find the appropriate answer?

1. Overview

Commencing with the foot brake system, it is a pedal connected to vacuum booster, which is used to stop or slow down the vehicle’s motor. This is also known as the system of hydraulic brakes that multiplies the foot-force applied in order to stop a car weighing several tons.
Whereas, the handbrake, also known as the parking brake, or emergency brake; is a straight pull handle near the steering column. This can also be a hand-operated lever at floor level next to the driver, or a foot pedal located beside the leg of the driver. Simply put, this means it can be in any of the above-defined forms in a car but is used only during an emergency stop or when the vehicle is in stationary state

2. Mechanical Difference

Foot Brake-- 

 

When the power brake is applied, the force is transferred to the master cylinder. This cylinder then generates a compressive force on the hydraulic liquid that passes through the brake lines to its caliper. Pushing the caliper against brake rotor, the liquid assists in slowing down the rotation of the wheel. In case of drum brakes, the same effect is seen; the only difference is that the brake drums are pushed against the two shoes by the piston.
Every time, when the driver steps on the brake pedal; the hydraulic force is distributed between the front and rear wheels. On average, 75% force is received on front wheels while 25% is received at rear car wheels

Handbrake

 

In most vehicles, hand or parking brake is a mechanical device that doesn’t depend on stored energy and is capable enough to deplete hydraulic circuit or compressed air. When handbrake is brought into action, it operates only via the piston in the caliper or on the dedicated shoe brake inside the rear rotor. In other words, parking brakes are dedicated only on the rear wheels

CABIN AIR FILTER

On newer vehicles you are likely to find the cabin air filter, it's job is to clean the air that enters the passenger compartments and HVAC( heating, ventilation and air conditioning) unit In some cars you will find it located under a panel at the base of the windshield while in other cars you will find it behind the glovebox There are two kinds of designs or construction of cabin air filters and it's maintenance depends on the construction your vehicle is using i. Dust only-- should be replaced every 20,000 miles or two years ii. Dust and odor-- should be replaced every 12,000 miles Note that replacements often depends on operating condition
