my brakes is soft as a number two

hello to you all
i have done my brakes today on my luego i have got a gold pedal box with a double reservoir which is gravity feed.
i have bleed the system twice and there is no leaks or air in my system,
but my pedal is soft as a number two and my brakes do not work untill you pump them very fast when you stop pumping them, then the brake fluid goes back into my reservoir and then brakes are soft again .
can any one help many thanks.

Sounds like a piston is returning too far and pushing the fluid back through the system, when you pump fast you push it out again. Are you using sliding calipers or opposed piston? if they're sliders make sure the do and are nice and free. Also if you have drum rears, make sure they are adjusted on the adjusters and not the handbrake cable.

As Pete says , also if you have rubber hoses you can use a brake pipe clamp on each hose in turn to determine which brake is at fault. If you have discs on the rear try letting off the handbrake cable , remove the brake caliper without disconnecting the hose and wind the piston out to take up most of the clearance between the disc and the pads , refit caliper and pump pedal a few times before adjusting cable. Also are the bleed nipples on top of the calipers? if not remove calipers without disconnecting the hose and place a piece of wood (thickness of disc) between pads , turn caliper so nipple is uppermost and bleed.

when blleding the rear calipers, as said before, make sure the bleed nipples are at the top, but also, shake the caliper and tap it a few times - the inner workings of the rear calipers are twisty and turny and air can easily get trapped in them.
