After all the snow, grit, salt, crap etc on the roads, decided to clean the VFR brake calipers yesterday. Front were pretty okay but the rear caliper/piston's were fairly crudded up. Got them cleaned up pretty good and the pistons came out spotless. (I didn't dismantle them, just cleaned them up while still connected so no bleeding required)
I used Holts brake cleaner with a toothbrush and then
GT85 which has a solvent, which evaporates, but leaves a coating of dry lubricant.
Sliders were moving very freely so I didn't need to interfere with them
