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

HOW LONG CAN YOU DRIVE ON A SPARE TIRE

Spare tires are a lifesaver when one of your regular tires pop in the middle of a highway or you may just find the car with a deflated tire. But, how long can you drive on a spare tire? The most common advice would be to check the owner’s manual that usually suggests not more than 70 miles at a maximum 50m/h (for a donut tire) as the rule of thumb There is no definite answer to this question because it depends on several factors. It happens mainly because the modern vehicles come with a donut tire, which is smaller than a full-size tire. The logic behind it is that people need it on rare occasions and don’t even use it for a long time. Also, a smaller tire saves space in the trunk 1. A Full-Size Spare If the spare is a full-size tire, given that it is the same size and type as the ones in your vehicle, you can drive it like a regular tire and use it until it wears out. You may think that the spare tire will be like a new one if you don’t use it. This is not true. If it is ...

SOME COMMON BRAKES PROBLEMS

LOW BRAKE PEDAL-- This happens when shoe adjusters on rear drum brakes are rusted or sticking and can no longer make up for normal lining wear. Adjusting the rear drum brakes may restore a full pedal but a more lasting solution would be to clean or replace the adjusters. Fluid leakage and worn out brake linings could also lead to low brake pedals SPONGY OR SOFT BRAKE PEDAL-- When air gets inside your brake system a spongy or soft brake pedal is what results. This often happens due to improper bleeding, fluid loss or a very low fluid level. To fix this you have to bleed all your brake line using only a recommended sequence EXCESSIVE BRAKE PEDAL TRAVEL-- If you experience excessive brake pedal travel, it could be that your brake linings are worn out or your drum brakes are misadjusted or your rear is getting worn out or there could be air inside the brake lines. It could also be any combination of both. This can be dangerous because the brake pedal may run out of travel before the...
