changed all my brake lines all round and front and rear calipers got it all bleed great brakes worked great for about 2 weeks went out in it today and the brakes were sh1t very spongy pedel checked all joints unions rubber hoses bleed nipples even the overload sensor there is no sighn of leaks any were not lost any fluid its still toped up to the line. re bleed it no air bubbles did a pedel test for servo thats ok aswell. when cars running spongy pedel when cars turned of the pedel gets a bit harder.:confused: any ideas.

If theres no leaks the mastercylinder is probably shot.

The pedal will feel very difficult/hard to press without vacuum assistance, id try moving your bias valve, this can affect the brake pedal feel alot if its not adjusted properly or is sticking in an incorrect place.

master cyl.test:if u hold the pedal down firmly(dont stand on it)while the engine is running and the pedal eventually goes to the floor then your master cyl. is shot!!providing u have no leaks of course!!:)
