Why Does My Car Shudder When Braking?
Car brakes may shudder during braking due to several reasons:
Firstly, uneven wear on either the brake pads or rotor can cause the shuddering sensation.
Secondly, a buildup of deposits on the hub can lead to the rotor sitting unevenly, resulting in brake shuddering.
Thirdly, damaged rotors or drums can be responsible for the shuddering sensation when braking.
Additionally, malfunctioning calipers can cause the brakes to shudder during braking.
Lastly, if new brake pads have not been properly broken in after replacement, they may contribute to brake shuddering.
Could the shuddering sensation during braking be caused by warped brake discs?
It is a fact that the discs were not warped at all. Our investigation, conducted with the help of our suppliers, has shown that every brake disc claimed to be warped actually has uneven patches of friction material from the brake pads on its surface. These patches lead to variations in thickness (run-out) and result in vibration during braking.
