      If the calipers have a built in parking brake you normallly need to use a special tool to turn the piston (needle nosed pliers may work). This will screw it back into the caliper so you can put the new pads in.

Adjusting the Caliper Piston for Changing Brake Pads

Hi! This is Jon from Expertvillage.com and in this clip, we will continue with step 10 on our procedure for replacing disc brake pads. Once you remove the brake pads, you’ll notice that there is a round, cylinder type object. This is the caliper piston. As your brake pads wear, the piston starts to move out, compensating for the brake pads getting smaller. What we need to do is, we need to take a C-clamp and push that piston back in since our new brake pads are going to be quite a bit thicker than the old ones. What you will want to do is, take your C-clamp, adjust it so it fits around your caliper, and touches the piston. You are going to slowly tighten your C-clamp, which will push that piston in since our new brake pads are thicker; we need to compensate for that. This is also pushing all that brake fluid through the brake lines up back into the master cylinder. You just want to tighten it until it doesn’t go anymore and then you can remove your C-clamp.
