Why Does My Car Feel Shaky When I Brake?
There are several potential reasons why your car may shake when braking, which include having a bad tire, a bent rim, an unbalanced wheel, a bad shock absorber, or missing/faulty suspension parts.
Are there any issues with my brake pads or rotors that could cause the shaking?
The most common reasons why your brakes may shake after new pads and rotors have been fitted can be attributed to a few factors.
Firstly, it is possible that the new brake rotors and pads were faulty. This can be due to manufacturing defects or quality issues.
Secondly, if the area where the brakes were installed wasn't properly cleaned, rust or dust may have fallen on the new rotor. This can result in uneven braking performance and shaking.
Additionally, if the caliper wasn't tightened enough during the installation, it can cause the brakes to shake.
Another reason for brake shaking is uneven friction material build-up on the rotor, which can occur over time.
It's important to note that new brakes and rotors come sealed in a protectant that needs to wear away after installation. This can temporarily cause some noise and shaking until the protective layer is worn off.
Lastly, if the rotors were not properly ground down during the installation, the new brake pads may have to groove themselves to match the grooves on the rotors. This can result in noise and vibration.
