Bad rotors new pads

The classic combo!

When you have bad rotors and new pads, you're essentially replacing the "brake shoes" (pads) with new ones, but the "brake drums" (rotors) are still worn out. This can lead to some interesting brake performance characteristics. Here's what you might experience:

Pros:

  1. Improved braking feel: New pads can provide a better braking feel, with more consistent and predictable stopping power.
  2. Reduced noise: New pads can be quieter than worn-out ones, which can reduce the squealing or grinding noises you might have been experiencing.
  3. Better pedal feel: With new pads, you might notice a more responsive and firmer brake pedal feel.

Cons:

  1. Reduced braking effectiveness: Since the rotors are still worn out, the new pads won't be able to fully utilize their potential. This can lead to longer stopping distances and reduced braking performance.
  2. Increased wear on new pads: The worn-out rotors can cause the new pads to wear down faster, which can lead to premature replacement.
  3. Vibration and pulsing: Worn-out rotors can cause the brake pedal to vibrate or pulse, which can be uncomfortable and affect your driving experience.

Recommendation:

If you've replaced your brake pads with new ones, but the rotors are still worn out, it's highly recommended to replace the rotors as well. This will ensure optimal braking performance, reduce wear on the new pads, and provide a smoother, more comfortable driving experience.

In some cases, if the rotors are only slightly worn, you might be able to get away with just resurfacing or turning them. However, if they're severely worn or warped, replacement is usually the best option.

Remember to always consult your vehicle's repair manual or a trusted mechanic if you're unsure about the condition of your rotors or pads.
