Used to disassemble 4 well stuck pedals: RAS does the job. For novices like me, I said a little. This extractor is used with a key 17: - To dismantle the pedal locking screw with the rear of the extractor which is a hexagon 14 is compatible with most pedals - To screw the extractor into the pedal. It takes a little stress to go to the bottom. If not screwed enough, it may spring and screw up the thread. - Then to screw the punch. There it is downright force if the pedal is stuck. Some lube and a few hammer blows can help.
