Why Does My Car Skid When I Brake?

A braking skid can occur due to several factors. First, over-braking, which involves applying excessive force to the brake and causing the wheels to lock up, can lead to a skid. Second, sudden braking, characterized by abruptly pressing the brakes, can cause the tires to lose traction and result in a skid. Another factor is over-steering, where the wheels are turned more sharply than the vehicle can handle, leading to a skid. Additionally, driving on slippery surfaces such as ice or wet leaves can also contribute to skidding. Finally, obstacles such as potholes or debris on the road can provoke skids.

Are your tires properly inflated?

When it comes to maintaining tire inflation, it is important to check the tire pressures regularly. It is recommended to use a reliable pressure gauge for accurate results. It is also essential to follow the inflation pressures suggested by the vehicle manufacturer, rather than relying on the pressure indicated on the tire sidewall. Additionally, it is advisable to check the tire pressures before driving, preferably when the tires are not hot and have been at rest. It is worth noting that it is normal for the pressure reading to be slightly higher (typically 2 to 6 psi) when the tires are hot.

Although the heat does not spread, it can cause costly damage and warping to the braking system and rotors. This can lead to expensive repairs in the future. It's important to be aware of the impact of speeding and hard braking on the lifespan of your brakes.

Did you apply the correct braking technique?

It is recommended to apply the brakes with enough force to experience a noticeable decrease in speed. Once the speed has been reduced to approximately 5 mph below the "safe" speed, release the brakes. This application should last about 3 seconds. To maintain a good braking technique, apply constant and steady pressure when braking.

When braking on steep downhill slopes, it is necessary to push harder and start braking earlier to ensure a safe stop. Similarly, when approaching tight curves, increased pressure is required to effectively slow down the vehicle. Additionally, it is important to leave ample space behind a stationary vehicle to allow room for maneuvering in case of emergencies.

The correct method for braking is to apply pressure smoothly and gradually up to the maximum point, and then release the pedal equally smoothly. This smoothness helps to maintain control of the vehicle during the braking process.
