Ok, I know that there have been quite a few threads regarding this issue but I just have a few questions that were not answered yet so I think I might ask one more time Several months ago my '06 BRM started to have a sticky clutch pedal. I had been able to pull it back with my toe and keep driving just fine until a few days ago, when no pressure could be felt at all when I push the pedal down. Here is what I observed: brake fluid level ok; no obvious leaking from the line or either cylinder. I decided to bleed it and see what happens. Well, I just didn't see any pressure building up in the system at all no matter how hard a buddy of mine pushed the pedal! Nothing comes out in the tubing attached to the nipple, not even bubble. So here goes my questions: 1. Does this mean my master cylinder is dead or just a lot of air in the system? 2. Do you recommend replacing both cylinders when I'm in there?(car has 220k miles) 3. I saw(forgot where) people say that o-rings need to be replaced every time the hydraulic system is open. But I was only able to find the o-rings at idparts. over $20 for two pieces of rubber seems very steep. Can I use some gasket maker to seal it? 4. Will Motive Products 0100 work with my car? Thank y'll for reading!
