Bad rotors can pose a significant danger by compromising the effectiveness of brakes. Furthermore, if wheel bearings are also faulty, it can result in damage to the wheel assembly to the extent that the wheel may detach while in motion.

Front brakes experience higher levels of stress compared to rear brakes, which increases the likelihood of warped rotors in the front, independent of the condition of the rear brakes.

Are brake discs Warped?

Contrary to popular belief, the brake discs were not warped in any way. Our extensive investigations, conducted in collaboration with our suppliers, have consistently revealed that so-called "warped" brake discs actually exhibit uneven patches of friction material from the brake pads on the disc surface. It is these patches that contribute to variations in thickness, known as run-out, and subsequently cause vibration during braking.

Are the brake pads causing the wobbling sensation in my car?

Worn brake pads can cause various issues when braking. One of these is a pulsating sensation, where you may feel vibrations or a shuddering feeling in the car's front end, particularly under heavy braking.

If the brake pads wear unevenly, this can also result in a pulsing or shuddering sensation during braking. Additionally, you may hear metallic scraping or grating sounds accompanying these vibrations.

When brake pads are excessively worn, they may expose metal on the pads that grinds against the rotors every time you brake. This can produce a grinding noise and potentially damage the rotors.

Furthermore, if you hear rubbing noise while driving at slow or fast speeds, it could be due to the friction between the brake caliper and the brake rotor.
