Brake lights stuck on So got new switch installed works fine, Then when car sits for a hr no pedal Checked system no leaks all good Took out new cyl replaced old one now got brakes but stop switch not working (new one that worked with other cyl) Brake lights stuck on Crack loose at master and goes out till brakes are applied What am I missing Any Ideas? (New cyl. looks to be leaking in front so I am calling that one junk out of box)
