Was it a brand new servo or a used one?

Also have you opened up the rear brake bias valve under the rear of the car as this enable you to belled the rears properly??

Hi,you'll need to bleed the master cylinder first before you attempt bleeding at the calipers.If you don't get any fluid pumping out at the master cylinder pipes when you crack them open a few turns and pump the pedal then the master cylinder seals are shot. When bleeding a master it's best to use this sequence

1.fill reservoir
2.loosen one brake pipe union on the master cylinder a few twists of the spanner
3.brake pedal down and hold it down (fluid should come out of the threads of the pipe/union, you may need to undo union more if nothing happens)
4.tighten brake pipe union
5.brake pedal up (fluid level in reservoir should noticeably drop)
6.repeat steps 2-5 until you get plenty of fluid out with no obvious air.
7.do the other pipes

Hi. Thanks for the reply. I will try this in the week. I have put a reconditioned master cylinder on it. Thanks again.
