Change brake rotors:

When you should change brake rotors – and how to do it yourself!

All disc brake rotors have a minimum safe thickness. Once the rotors wear beyond this minimum thickness, they cannot get rid of the heat produced by repeated braking.

Heat is the enemy of disc brakes. Excessive heat will increase your stopping distance and cause your rotors to warp. In severe cases, this heat buildup may cause your brake fluid to boil, reducing your stopping power to zero.

A pedal that pulsates on light braking may indicate warped disc brake rotors. Squealing or scraping when braking may also indicate brake trouble.

Don’t take chances with your brakes. Take good care of them with quality auto parts – including the best brake rotors – from Advance Auto Parts.

Why you should inspect your brake rotors every 15,000 miles:

Your disc brake rotors take serious punishment. Every time you hit the brakes, the brake pads compress the rotors with thousands of pounds of stopping power. The material in the brake pads will eventually wear down the rotors.

If you have a warped or worn brake rotor, your vehicle will take longer to stop. Malfunctioning or poor performing brakes are dangerous. Don’t ever play games with safety. You don’t want to drive with a worn brake rotor. Inspect your brake rotors every 15 - 25,000 miles.

How to change brake rotors on your own – and save:

Consult your vehicle repair manual for exact brake rotor service procedures and tools required for a brake rotor replacement. Siphon brake fluid from the reservoir or drain from the bleeder valve before compressing the caliper piston, as spillage may occur.

  1. Slightly loosen the lug nuts. Raise and secure the vehicle. Depress the brake pedal 20 times to release residual pressure. Remove the wheels and unbolt the brake caliper fasteners. Removing these fasteners may require specialized tools.
  2. Remove the caliper and hang it from the vehicle using heavy wire or a bungee cord. Never allow the caliper to hang by the brake lines.
  3. Remove the worn brake rotor from the wheel studs and replace with the new rotor. Use a c-clamp or caliper spreading tool to compress caliper piston. Clean the rotor surface with brake cleaner.
  4. Add the new brake pads to the caliper and slide the caliper over the rotor. If the caliper does not slide easily, then the caliper piston is not fully compressed.
  5. Follow your repair manual procedure and tighten caliper fasteners to correct torque. Add fluid if needed. Check the brake pedal and bleed system if necessary. Reinstall the wheels. Test the brake operation.
