The rubber hose, which is the hydraulic line, flexes to allow the caliper to pivot up after removing the lower bolt, so do not disconnect any hydraulic lines. At this point, brake pads are easily visible and can be evaluated to see if they need to be replaced at all. Even if the metal wear indicators are not yet touching, the pads need to be replaced if the friction material is 1/8-inch thick or less at any point.

New front disc pads usually come with new clips, so use them to allow the pads to slide back and forth easily and dispose of the old clips. Do not bother looking for retaining screws for the clips because they simply snap in place. If the new pads come with graphite-based grease, apply it to the clips of the new brake pads to prevent squeaking noises. When changing the second break pad, monitor the brake fluid level because the combined fluid volume of two calipers may cause an overflow. After changing the brakes, test them under safe conditions to be sure they work properly.
