RE: 2005 SRT6. I'm replacing all brakes and rotors. Rears were no problem. When I removed the front caliper and compressed the first puck the other puck extended. Now I cannot get it to compress. I took the caliper off so I can get to everything and still, even with a pipe compression clamp I cannot get it to budge. I know some Mercedes require the puck to be rotated so I rotated the one on the SRT6 and still no luck. I'm sure there's an expert on here who has the solution. Old Dog, new toy. I appreciate any insight.
