Tighten Right
Another cause of warped rotors is improper wheel nut torque. Over-tightening of wheel nuts can cause undue stress and warping of brake rotors. The best solution is to use a torque wrench. This is an especially important consideration with aluminum or performance alloy wheels. Proper torque values are also crucial when refastening slider pins, caliper mounts and associated brake hardware. A service manual is the best place to find the correct information on brake and rotor replacement procedures. When working on your brakes remember that "good enough" simply isn't. Taking the time to do it right is the best and safest route to take.
Loosen the wheel lug nuts first. Jack up the car safely and remove the wheels. Work on one side. Refer to the other side for assembly.
First Loosen Wheel Lug Nuts
Remove the brake caliper as an assembly. Do not allow the caliper to hang from the brake lines. Secure with wire if required.
Remove the Brake Caliper as an Assembly
Don't forget to remove any fasteners or screws before attempting to separate the rotor from the hub.
Remove Fasteners or Screws Before Separating the Rotor From the Hub
Remove the old rotor. One-piece rotor and hub assemblies require removal of the spindle nut and the rotor hub assembly as a unit.
Remove the Old Rotor
Reverse the removal procedure with the new rotor. Use brake cleaner to remove all grease or residue from the new rotor before installing the caliper. Tighten all fasteners to the correct torque.
Clean up the New Rotor
