5 Busted myths about vehicle brakes

myths of car brakes

Many have heard about different myths of vehicle brakes. Over here we will be debunking 5 of the most popular myths of vehicle brakes.


Myth #1: Brake pads need to warm up for best efficiency

Unless you’re an IndyCar or F1 racer, the brakes on average street vehicle produce just enough friction to stop the car even during winter. The brakes will bring the car to a halt either way regardless of the temperature.


Myth #2: Brake noises are signs you have to change new brake pads

Some braking noise could be caused by worn-down brake pads. The brake pads are built with a small metal tab that will rub against the rotor when the pad is worn almost all the way down. The high pitch squealing noise is a sign to visit your service centre for a brake job.

However, they are not the only potential cause. Any time two metal parts rub or vibrate against each other, high and low-pitched noises can be developed. Before the squeaking and squealing turn into screaming, bring your car to a car service centre to help identify your brake’s problems.


Myth #3: Slotted or drilled brake rotors improve braking performances

Drilled or slotted rotors will not improve braking performance on street vehicles unless you’re an F1 driver. Racecars use slotted rotors to enable even distribution of heat, but these offer no real benefit to street vehicles and in fact, this technique decreases the life of the average rotor.



Myth #4: Wet brake rotors increases the braking time

Braking on a wet road can take approximately three times longer than on dry roads. However, the reason behind it isn’t because of a damp brake system. The strong centrifugal force of the rotating wheel will get rid of water on the rotors.

With that said, wet tires and roads cause the increase of braking time, not wet brakes. Therefore, reduce your speed on a wet and slippery floor to gain more traction, increasing the contact point between the tires’ tread and the road.


Myth #5: Hard pads are better than soft pads

False, there is no such thing as hard or soft pads, they are just different methods of getting friction between the pad and the rotor.

Hard pads use their rough surface to create stable friction over a wide range of temperatures while soft pads generate brake torque using adhesion friction. The friction materials will coat the rotor smoothing out the rotor surface preventing rotor wear and reduce noise.
