Title: brakes questions
Post by: EsSeX dAn on 06 March 2012, 21:36

couple of questions for you all, hopefully someone can help!
1) when replacing a master cylinder do you just bolt it in and it works or do you have to line anything up and slot ot in or anything like that?
2) the brake system is all fully bled, i used a 'gunson easy bleed' thing that you connect to the spare tyre and use that pressure to bleed it. but when the engine is running, the pedal goes to the floor with not much effort. but when the engine is off the pedal is hard (as it should) any ideas?

I believe the brakes have to be bleed with the engine running, pedal going to the floor suggests air or faulty master cylinder.
