"Anything else I need to worry about - the caliper bore looks good I have no idea if the piston seal is the original or has been replaced - it looks as the design does not include what I would describe as a dust/water seal/bellow."Yep, there's a complete absence of weather/dust seal in these original designs. And one of the considerations in maintaining them.Seal groove scrupulously clean, new ( soft and chewy seal) and silicone grease to assemble it is all that's needed. The piston "cover" plate effectively tries to compensate for the caliper swinging in an arc due to pad wear. Tries to allow the moving pad to remain aligned to the disc rather than be skewed by the flat face of the piston as the caliper effectively moves in an arc. This partially successful, but a compromise certainly
The split pin holds pad B into the caliper body. The pin goes through the pad hole at the top, and through the hole in caliper B, then the ends spread. The reason for the swinging caliper design was at the time Lucas Hurling had a patent on opposed piston calipers, so Honda came up with this solution. Sent from my POT-LX1 using Tapatalk
