Hi, When I was trying to bleed my braking system on my Peugoet 306 (1994) the bleed-screw of the wheel-cylinder on the left-rear side broke. I tried to remove the remaining part of the bleed-screw with a "stuck bolt/screw extractor", but this snapped off as well. Does anybody know how to fix this problem, besides from fitting a new wheel-cylinder? And does anybody have any hints on how to slacken the remaining bleeding-screws without breaking them? Thanks, Peter
