Brake caliper seals how to make them last.

This is an example of a bad Brake caliper. The seals go bad or if you did not change your brakes. If it goes passed the friction material it could blow the seal out. Sometimes the seals just let go. So, make sure you clean your brake calipers every time you change your brake pads or rotors. You can also clean them out with an air hose and a fitting. You can use water as well. By the way always greese your contact points when you change brake pads.
