The N/S rear brake caliper has a slight leak from the handbrake actuator arm. I have got the rebuild kit. Removed the caliper. Cleaned it all up. Removed the piston and both the large seals. The leak is from the rear of the cylinder and I can see the small o ring seal in the kit that is obviously the one that is leaking but how do I get the mechanism out of the caliper. There are 3 spring (clips?) and what looks like three lugs but how does it come apart? Don't want to damage it by going at it like a bull etc.. Can anyone explain or point me to a website with a diagram?
