I have just replaced some of the brakelines on my LH, but after I bleed the brakes (done it about 6 times now!) the pedal still goes to the floor, the only way to get any pressure is to pump the pedal a few times and hold it.
Any ideas?

There must still be some air in the line somewhere. Keep going until you get a hard pedal. I am of course assuming there are no leaks since replacing the brake lines.

You may have air in your master cylinder, messy job bleeding but it sometimes must be done. Assuming your bleeding them in order, rear left, rear right, front left, front right!

yes, im bleeding longest to shortest.
how do you bleed the m/cyl? it doesnt bleed it self when you bleed the brakes?
I am probably gonna replace the m/cyl now anyway, for under $150 I cant go wrong!

MAAKKKKAAA!!! I had the same problem!! The master cyinder seals have sh=t themselves!! Trust me on this! Dattoman put me onto it. Spend the $150 and get a new one and all will be bliss. The fluid is by passing the seal in the M/S>

Rory is probably right, when you bleed the brakes you are pushing the master cylinder into areas that haven't been used, and ridges and crud build up which can damage the seals. It can also be crap blocking one of the ports, 2 on each, front and back systems, not normally noticable with normal brake operation, but would still entail a pull apart to fix, But, saying that you can try pumping very fast until you build up pressure, and see if that does the job, but obviously there is a problem there, and with brakes it's probably a good idea to have it working properly. $150 is probably a good investment. Good Luck Jim.

DOH swapped them back, problem solved
