It's either Froze in, or rusted in. Need to get the brakes adjusted on a wheelchair, but the screws the hold the bar that the hand brakes are attached to, are either rusted or frozen in. checked the manual, and they are torqued in at 115 FT LB's . I can't move those screws. they are STUCK !! Would a 3/8 inch electric drill have enough power to loosen those screws up ?
