Bled the brakes removed all the air and started the car my foot went straight to the firewall.. Checked fluid all good, the booster is new reconditioned and this is the first time i attempt to use it. Pedal still goes to the floor, any ideas would be appreciated. I think that there should be a one way valve between the booster and inlet manafold, Will buy one tomorro and try it

Sounds like it may be the master cylinder...have you replaced that yet?

If the master is new, have you bench bled it before putting it in the car and bleeding in the car?

Yepper, what Bob said...if you did not bench bleed it...you are going to have troubles...without bench bleeding it, you'll be chasing air until Easter...maybe longer.

Thanks for the reply, you have got me concerned how do i bench bleed it, and are you aware how much work is envolved in removing that sucker.

Fit a plastic/rubber tube, from the two outlets, and run them back into the reservoir. Your new master cylinder should have come with a plastic 'nut' with a nipple, for just that purpose. If you can 'hold' the master cylinder in a vice, with it plumbed as descibed, use a screwdriver or similar, and just keep pushing in and out on the plunger, until there is no more air...Then re-install onto the car..
