on trail boss 250 front dusk brakes for frozen after setting for ten years. how do you free them up?

 

Small pry bar to spread the pads and force the caliper piston back. More than likely you'd need to replace the caliper piston o-rings,clean the piston or replace it along with pads if worn.https://www.ebay.com/itm/1989-2013-P...JZPY4A&vxp=mtr Plus bleeding the brakes afterwards with fresh dot 4 fluid.That's where a mityvac comes in handy if you have one.
