Finally retired and building my project bike
McCabe-Thiele (Ted):
My 400 & 500 have the nylon type ring on the one static pad back.
I think Grahame is talking about the piston to pad contact being convex or concave.
K2-K6:
An original 750 caliper sectioned schematic shows the fixed pad as shamferred and piston side pad with relief around periphery.
Dome on back of fixed pad, as Graham states a dome under the piston pad, both to allow pad "float" to keep alignment flat with disc as caliper swings geometry with static pad wear.
Over the years different makes of pad have been supplied with shamferred edge or nil relief in my experience.
"Plastic" piston types in calipers are ordinarily Phenolic resin Ted, very high temperature resistant material with added advantage of low heat transfer to brake fluid given as advantage of use.
My experience is that you have to go unbelievably hot before that route into fluid would concern you, the whole caliper would be baking by then anyway. I've run v-high temp pads in competion car, up where the disc glow yellow and the wheel bearing grease starts to run out as oil! and without fluid boiling.
McCabe-Thiele (Ted):
I was using Plastic as a generic term in the broadest possible terms for anything from Nylon to Bakerlite sometimes derived from Petrochemicals.
Phenolic Resin nice to know the right handle to use - do any motorcycle manufactures use them in callipers?
gamma:
Battery fitted, no leaks as of yet
Making brackets to install front indicators, I shall fibreglass them to the inside of the fairing
Still looking for some high density foam to make a seat
andy120t:
Have you looked at camping rollmats for foam?
