2. Rotors not Seated Properly: When new rotors are installed, the surface needs some time and friction, called bedding in, to get used to the brake pads. Failure to properly bed in rotors after replacement might cause some shuddering as they are seating in.
3. Brake Pad Material Transfer: Residue and fragments of old, disintegrated brake pad material left on the surface of rotors can create a rough surface, leading to vibration and shuddering.
4. Faulty Brake Calipers or Wheel Hubs: Issues with brake calipers, like sticking or malfunctioning pins or sliders, can cause an inefficient grip on the rotors, leading to shuddering.
Likewise, problems with wheel hubs or bearings, such as misalignment, damaged components, or play, can also induce a shaking or wobbling sensation when applying the brakes.
5. Improper Lug Nut Tightening: If the lug nuts securing the wheels are not properly tightened, or tightened unevenly, it can cause the wheels to be slightly off-center and create vibrations when braking.
6. Suspension Issues: Worn or damaged suspension components like control arms, bushings, tie rod ends, or ball joints can cause shaking, pulling, or vibration during braking.
7. Tire Balance: If tires have unbalanced weight distribution, especially after recent tire work, it can result in vibrations at higher speeds and while using the brakes.
8. Driveline Issues: Although less common, problems with the driveline components, such as a faulty driveshaft or universal joints, can cause similar shudders or shaking.
Note: Always have a professional mechanic accurately diagnose and address the specific cause of shaking upon braking, especially if the brakes were recently serviced or replaced, to ensure safety and prevent further damage.
