Brake master cylinder

[djb222]

Just in the process of finishing off my car after a very lengthy build ( 10 years or so, on and off) anyway the end is in sight. I moved the car into my garage, a 50m drive and the brake pedal went very spongy and I had to pump the brakes to get pressure. So, I found some bubbles in the fluid reservoir and decided to bleed the brakes. The front bled ok and on topping up the reservoir found a few drops of fluid around the said reservoir. Trying to bleed the rear brakes I found the brake pedal hard, on looking at the reservoir again there was a lot of fluid on the floor pan. As I was doing this job solo I called my wife as a second pair of eyes. With all bleed nipples tight I depressed the pedal several times and even from the car I could see a jet of fluid shoot from the reservoir.

My thoughts are because the car has been standing for a good while the fluid control valve in the master cylinder has failed resulting in fluid being forced back into the reservoir or could it be seals? Has anyone come across this before or any other ideas?

Has anyone got any photos or comments on securing or protecting the brake lines front and rear please. I've looked at the spiral wrap but feel they need additional fixing.

Regards

Thanks Steve,

the master cylinders were probably sitting around for about 18 months before brake fluid was put into the system, so I would hope the seals wouldn't have perished. Perhaps they are just faulty, I'll take the cylinder off the car and have a good look to see if I can just replace the seals or the cylinder.
