Motorcycle Repair: break caliper, caliper pistons, piston compressor

Question
i had taken my front wheel off and my cousent hit the front break leaver. how do i open them back up

Answer
To do this properly you need a brake piston compressor, but depending on how free the caliper pistons are you may be able to lever them back using a large screwdriver.  Do not force against the friction material as you will damage it, but you can lever against the metal of the brake pads.  Do not try to do this quickly, it will never move quickly, just put a gradual force on it and you should start to see it move.

Good luck,  Jan
