Inspired by Chris Heerschap's piston exposure tool.
As it says on the tin.
Fits Shimano single piston XTR BR9100 - also is said to work for SRAM Avids.
Remove the pads - take Chris' piston spreader thongs, insert from the top.
Happy cleaning
BTW, those holes... I like putting holes into things. You can attach a string through the top hole to hang the tool when not in use.
