Rt front brake locks up randomly, locked up checked caliper bleed, drove 75 miles with no issues, next day drove 20 miles and rt front break locked up again. so replaced caliper and brake line, drove 10 miles testing it, drove fine, waited 30 min, it was locked up again unable to drive, next day got in drove fine. when this happenes the stering becomes stiff and wobbly as flat or low tire would feel
