What causes shuddering when braking?
What causes shuddering when braking?
Brake shudder is the vibration that you feel through the steering wheel when you hit the brakes. If your brake discs are unevenly worn the brake pads come in contact with the flat spots present in the rotor’s surface which causes the vibration that we call brake shudder.
When do energy changes in braking cause problems?
Energy changes in braking When a force is applied to the brakes of a vehicle, there is work done on the friction between the brakes and the wheel. This reduces the kinetic energy of the vehicle, slowing it down and causing the temperature of the brakes to increase. Decelerating from very high speeds too quickly can cause a number of problems:
Which is larger the braking or Accelerating moment?
The braking moment is thus counteracting both the rotational inertia of the wheel, as well as the force couple from the ground/axle forces. Of these, the force couple is much larger (stopping a wheel without the car attached would be comparatively easy for the brakes).

Why does intermittent stalling occur in a car?
One of the more unusual causes of intermittent stalling we’ve heard about is a defective vehicle speed sensor. When the vehicle stops moving, the PCM may not engage the idle speed motor (carbureted engines) or idle air bypass motor (fuel injected engines) so the engine will idle normally.
What causes a car to accelerate and brake?
The deformation of the tire is responsible for the contact patch which generates the friction forces that allow a car to accelerate and brake. The physics of the frictional contact between the tire and ground can be very complex, as can the geometry of the tire.

Why do cars have anti lock braking systems?
Any car with well-maintained brakes has sufficient braking power to cause the wheels to lock, even in dry conditions with good traction. For this reason many cars now include anti-lock braking systems (ABS) , which detect wheel locking and rapidly pulse the brake force to prevent locking.
