I know I can just use a screwdriver in lieu of this tool, but the curved handle enables me to wiggle the tool back-n-forth so I can give the pistons a little extra push
I use this tool mostly for cleaning the pistons on brakes. But its a must have tool for doing any kind of maintenance on hydraulic brakes. Does not damage the pistons. Its made solidly and will last forever
Very helpfull to retract Sram 4 pistons, cause they are particular hard to move.
Works very well. If you have disk brakes you should get one of these as you will sooner or later need it. Wide flat head screw drivers may do the same, but this tool is more convenient and less risky to use.
