Range Rover Brakes!!

Changed the brake pipe (Front wing to rear section) today. Bled the calipers as per a normal car. When i turn the key i the Hydrolic pump (off side wing immediatly in from of master cylinder) sounds as if it is pumping air.

I have bled this (nothing much came out), and have bled the small unit behind it (which took 5 ltr of fluid and still had air bubbles in it).

Anyone know what the hell i am doing wrong??

Wot a coincidence I bleed mine yesterday! As you mention a pump I assume it has ABS (same as mine). I followed the descrption in the Haynes manual for bleeding using a pressure bleeder.
1. Fill the reservoir to the max level
2. Connect pressure bleeder
3. Open the bleed nipples on the front calliper that are behind the pistons in the following order o/s outer, n/s outer, n/s inner and o/s inner (ignition off)
4. Bleed the pump (ignition off)
5. Bleed the accumulator, this at the end of the braded hose from the pump. Connect bleed tube and open nipple, turn on ignition for 3-4 seconds repeat until no air con be seen.
6. Bleed one of the nipples on the hydraulic booster (big block with the reservoir on top). Attach pipe and open bleed nipple, depress the pedal and turn on the ignition for 3-4 seconds repeat until no air is seen. Repeat for the other nipple on the booster.
7. Now do the remaining four nipples (1 on each calliper) again open the nipple depress the brake pedal and turn on the ignition for 3-4-seconds repeat until no air can be seen.
8. Turn on ignition pump should go off in 45ish seconds (mine took a bit longer)
9. Keep the ignition on and using the lower 2/3 of pedal travel bleed the four nipples on the front calliper behind the pistons again.
10. Disconnect the pressure bleeder and with the ignition on and the pump stopped (system pressurised) depress the brake pedal a few times. If the pump comes on after two depressions the system needs to be bleed again.
This is the method for bleeding the whole system and you really do need a pressure bleeder. It’s so much easier. If you have any probs gives a shout.
Apologies for spelling and grammar.
Edited to add this method is for a 91 "classic" Rangie not sure if it works on a P38A.

Done!!!!!

What a nightmare job that was. appreciate the help.

After totally covering myself with brake fluid when i eventually got pressure, i will remember to use a garage for that job in future.

Yep there's no better fealing than brake fluid running down your arm and all over the paint work, Still at least it's done
