How to Stop Disk Bicycle Brakes From Squeeking

Bicycle disk brakes are relatively simple and easy to maintain. One of the more common problems they encounter is squeaking. Squeaking is a high-pitched squeal that happens when you apply pressure to the brakes. This is annoying and somewhat embarrassing, but it can also be an indication that there is something wrong with your brakes. When the squeaking begins, it is time to replace the brake pads, as well as clean the rotor.

Things You'll Need

Instructions

    • 1

      Remove the wheel from the bicycle. You will need a wrench to do this.

    • 2

      Remove the disk brakes from their calipers. If they are held in using cotter pins, take your pliers and pull the pin out. If the brakes are held in using a screw, you will have to find the proper-sized Allen wrench to remove them. After they are removed, inspect them. Most likely you will find that they are worn down. If they are worn, you will need to replace them. If they are not worn, simply clean them by scraping them with sandpaper and then reinstall.

    • 3

      Clean your rotors by wiping them down with a clean, rubbing alcohol soaked rag.

    • 4

      Install new brake pads by reversing the process you used in Step 2.

    • 5

      Squeeze your brake handles several times to ensure that the new pads are going to work.

    • 6

      Inspect the brake caliper to ensure that it is centered over the wheel. If it is not, you might need to center it by loosening the mounting bolts that secure the brake caliper to the fork. After you have done this, squeeze the brakes. This will force the brake caliper to center itself on the rotor. Tighten the mounting bolts.
