Q:

What does it mean when a car vibrates when the brakes are applied?

A:

Having a car vibrate when the brakes are applied is a common problem for many car owners. Most of the time, this is a result of the front brakes being worn out, which is usually due to warping.

Warping of older brakes usually leads to uneven force distribution around the brake plates when the brakes are applied. This results in vibration of the wheel, which is then transmitted to the rest of the car. The severity of the vibration depends on the severity of the brake pad warping. Pads that are severely worn out tend to make the car vibrate when brakes are applied when driving slowly, but less severe warping is only noticeable when the brakes are applied while the car is moving fast. This in itself is not a major problem, so one can continue using the car for some time once they notice the problem. However, it is important to have the car inspected soon, since the problem could rapidly become worse and cause more noticeable effects. Neglecting a brake problem might result in damage to other parts of the car, such as the tires, which would require more money to repair later on. As brake problems progress, they also make use of a car increasingly unsafe.

    How do you add brake fluid to your vehicle?

    A:

    To add brake fluid to a vehicle, clean the reservoir cover, open the reservoir, check the fluid level and fill the reservoir to the indicated level. If the vehicle is equipped with an antilock braking system, check the owner's manual for special instructions before opening the cap.

  • Q:

    How do disc brakes work?

    A:

    A disc brake uses a set of calipers to press braking pads against a disc attached to the wheel. The friction from this contact slows the wheel and, by extension, slows the vehicle. Most cars have disc brakes attached to the front wheels and older drum brakes on the rear, while some have disc brakes on all four wheels for maximum control.

  • Q:

    What could cause a car to shake when braking at high speed?

    A:

    A problem with the brake disk rotors is the most common cause of vibration when braking at high speeds. Rotors are circular metal parts found behind the wheel of the vehicle that the brake pads press against to create friction and stop the vehicle. Small irregularities in the rotors transfer to the steering wheel when applying the brakes. Another cause of vibration is improperly tightened lug nuts.

  • Q:

    How long do brake rotors last?

    A:

    While disc brakes tend to last anywhere from 30,000 to 50,000 miles, the length of time brake rotors typically last depends on several different factors. These factors include how often the brakes are applied, how hard they are applied, the weight of the vehicle and how often the brakes have been serviced.
