If it's anything like the caliper on my 200q20v and an earlier 5ktq I've 
disassembled, there's a spring clip holding a plate that surrounds the 
threaded rod the piston rides on.  Get the clip off and you can, with a 
little effort, pull the rod out.  Beneath that is the chamber holding the 
parking brake parts.  The parking brake  item that pushes on the base of 
the rod to push the piston against the brake pad I (for lack of any source 
of formal nomenclature) call a peanut.  It's a piece of metal rod rounded 
off at each end.  One end goes into a detent in the bottom of the rod, the 
other into a concavity in the side of the parking brake arm that extends to 
the outside for attaching the cable.  You have to extract the brake piston 
rod in order to get the peanut out of the way so you can pull the parking 
brake cable arm assembly out of the caliper.  I'd like to know what 
lubricant is supposed to go into the peanut chamber.
