Every time you apply the brakes you think you&#39;re going to lose a filling. Thankfully, it&#39;s easy to replace your brake discs, and not at all expensive.

Remove the brake caliper just like you were <a href="https://www.thoughtco.com/how-to-replace-your-brake-pads-281392" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="1">replacing your brake pads</a>. Once the caliper is unbolted hang it out of the way using a bungee cord or similar hanger. This is so you don&#39;t have to unbolt the brake line.</p>Once you&#39;ve removed the brake caliper, you have to remove the structure that was holding the caliper and pads in place, called the carrier. Removing it is similar to removing the caliper -- two bolts on the back and it&#39;s off. Be sure to put all of the parts you remove in a safe place with the bolts that they go with.<p>With everything out of the way, you can finally start removing the old brake disc. Your disc is held in place by one or two set screws on the front. These may seem like nothing, but they can really be stuck in there.</p><p>Using a large Phillips head screwdriver, remove the bolt or bolts holding the brake disc in place.</p><p>Sometimes the screws will be stripped or otherwise damaged. In this case, you&#39;ll have to <a href="https://www.thoughtco.com/removing-a-stripped-or-otherwise-screwed-screw-281716" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="1">drill them out</a>.</p><p>With the screws removed, slide the old brake disc off the hub. If it&#39;s stubborn, give it some taps with your dead blow hammer to loosen things up.</p>With the old, stank disc off, you can slide your shiny new brake disc into place. Installation is the reverse of removal. Don&#39;t forget to replace the brake disc screws.
