If you can feel a pulsing sensation through the front brake lever (or rear) under gentle braking, or the front end violently judders at high speed with the first stroke of the lever then it’s a sign the discs are warped.

How do you check motorcycle rotors?

You’ll be checking two things: rotor thickness, and the surface quality of your brake rotor. All rotors have a designated minimum thickness, and by checking this with a micrometer or caliper, you’ll be able to tell quickly and easily if your disc is thick enough.

What happens if you put new brake pads on bad rotors?

If new brake pads are put onto a vehicle with damaged rotors, the pad will not properly contact the rotor surface which will reduce the vehicle’s stopping ability. Deep grooves that have developed in a worn rotor will act as a hole-puncher or shredder and damage the pad material as it is pressed against the rotor.

Can I put new pads on old rotors?

If you put new pads on old scored rotors, the effect is even worse. The best thing is new pads on new rotors — the reason that rotors are turned is to smooth out the surface to let the pads bed to the rotor. PS: this applies to all friction surfaces such as clutches — change the clutch and resurface the flywheel.

What happens if rotors are not replaced?

Brake rotor unevenness leads to pad wear, and if unchecked, pulsation with high-speed braking. This means the tires wobble and vibrate, leading to a jerky steering column and to anti-lock brake system failure. Replacement of the rotor is critical in this case.

How much do new rotors cost?

Brake rotor replacement costs will cost between $200 and $400 for the parts and about $150 in labor costs. This means that you are looking at around $350 to $500 for a total brake rotor replacement job.

What causes rotors to go bad quickly?

Common Causes of Worn Rotors

Panic or emergency braking at high speeds can cause rotor wear. The friction from the brake pad grabbing the rotor can cause high enough heat to result in wear.

Do you have to replace all 4 rotors at once?

Recommended Services

As long as you have both front disk brake pads replaced and rotors turned or replaced as well, it should be fine to complete the rear brakes shortly after. Although it is recommended by Ford to replace all four wheel brakes at the same time for safety, your idea should be OK.
