Hi all, i'm still here getting more and more mad about this sodding abs system on my '92 classic.
Right, the story so far:

had new disks, calipers and pads, went to bleed system... Abs pump packed up :doh:

found a replacement working pump after a month of searching, fitted it, went to bleed system... master cylinder siezed and some idiot had knackered the nut type thing that lets you get into it.

Finally got a new master cylinder, fitted it, bought a pressure bleeder and followed the haynes manual to the letter until i got to the point where i have to bleed the hydraulic boosters (after bleeding the pump and accumulator, the latter with the pump running) opened the bleed nipple, pressed the brake pedal fully, switch on the ignition and bled the first booster... fluid clear, close nipple..... pump starts making a god awful scratchy clicking noise as if its full of air.
If i ignore this, and continue on the power circuit, i get to finally pressurising the system and the pump doesn't cut out

Someone please help me... or failing that, anyone want to buy a cursed range rover 3.9efi???:confused2:

get some blue tissue,soak in petrol leave can of petrol in vehicle,make sure enough blue tissue has trailed away from vehicle,light blue paper and retire,i have been close to this myself,i think because of the complexity of the braking system i would take it to the garage,i do like doing work where i can,but i think this could be beyond the home mechanic,i may be wrong,but it is not a job i would want to tackle,as i think through shear frustration i would very soon have a burnt out shell.

Faulty pressure switch? Sounds like you've done the hard bits, so checking out the pressure switch should be reasonably straight forward.
