What are the signs of bad brake rotor?

If you notice a vibration when you apply the brake, you may have a bent brake rotor. Excessive heat can cause your brake disc to warp. Another issue is a grooved rotor. If you don’t change your brake pads when needed, you can cut grooves into your brake rotor. A grooved brake rotor can cause poor braking performance and damage your brake shoes. When this happens, you need to replace your brake rotor.

Do I need to replace mounting for front and rear rotor at the same time?

Your front bakes and your rear brakes are two completely different braking systems. Because of this you do not need to replace your front brake rotors and rear brake rotors at the same time. Most of your braking power comes from the front braking system. Different types of brake pads and how you ride all effect the longevity of the parts incorporated into your braking system. Best practice is to check your front and rear brakes a few times a year to make sure everything is in good working condition.

Do I need a torque wrench to change brakes?

You should use a torque wrench when changing your brake rotor or when installing your caliper bolts. Your brake caliper bolts and brake disc bolts should be torqued to the recommended specification. If you don’t have a torque wrench, you just need to make sure the bolts are tightened down completely, but it is highly recommended to use a torque wrench.
