Hi guys. Put new front callipers on the truck and can’t bleed this system!!!

Is there anyone who can give me a step by step guide?
Apparently these cars have their own way of doing this
Thanks in advance

Having trouble putting a copy of instructions on but if you google how to bleed p38 range rover brakes a copy of workshop manual on how to do it comes up.
Hope this helps
 
Service repair no - 70.25.02
Equipment: Bleed tube and a clean bottle containing a small amount of clean brake fluid.

CAUTION: Thoroughly clean all bleed screws, filler cap and connections using only clean brake fluid. DO NOT USE MINERAL OIL I.E. ENGINE OIL ETC.

MAINTAIN CLEANLINESS THROUGHOUT.

NOTE: Do not allow reservoir fluid level to fall below ’MIN’ level during bleeding. Regularly check level and keep topped up to ’MAX’ level.

WARNING: Do not use previously used brake fluid. Ensure only new fluid is used, taken from a clean sealed container. Carefully dispose of unwanted fluid in a sealed container, marked USED BRAKE FLUID.

1. Depressurise system. See this section. NOTE: Ensure ignition remains OFF until instruction 13.

2. Fill fluid reservoir with specified fluid to ’MAX’ level.

3. Bleed master cylinder as follows: Open bleed screw on booster, when fluid appears, close bleed screw.

4. Fit tube to bleed screw.

5. Open bleed screw, depress pedal slowly and progressively.

6. Close bleed screw. Release brake pedal.

7. Repeat instructions 5. and 6. until fluid is clear of air bubbles.

8. Open bleed screw, fully depress pedal, close bleed screw.

9. Bleed front calipers, driver’s side caliper first, as follows: Open bleed screw, depress brake pedal slowly and progressively, Close bleed screw at bottom of each stroke, release pedal.

10. Repeat instruction 9. until fluid is clear of air bubbles.

11. Open bleed screw again. Fully depress brake pedal, close bleed screw.

12. Repeat instructions 9. to 11. for passenger side caliper.

13. Bleed two booster bleed screws, starting at the front bleed screw, as follows: Open bleed screw, depress brake pedal, switch ignition on.

14. Allow fluid to flow until clear of air bubbles. Switch ignition off, close bleed screw, release pedal.

15. Repeat instructions 13. and 14. for the rear booster bleed screw.

Bleed each rear caliper, driver’s side caliper first, as follows: Open bleed screw, depress brake pedal slowly and progressively.

17. Switch on ignition for 4 seconds. Switch off ignition for 4 seconds. Repeat until fluid is clear of air bubbles.

18. Switch off ignition, close bleed screw, release pedal.

19. Switch on ignition, wait for ABS pump to stop running. Press brake pedal down firmly and fully release it five times.

20. With ignition on, repeat front caliper bleed instructions 9. to 12. Use only the lower two thirds of pedal travel when bleeding.

21. Repeat instruction 19.

22. Check/top up reservoir fluid level, See this section.

NOTE: If ABS pump makes a ticking noise when running during this procedure, repeat instructions 13. to 19. When the bleed procedure has been successfully completed, the ABS pump will not make any ticking noises.
 
With regards the above, top up the brake after each step. It isn't always obvious how low it is getting.

The booster screw is down the left hand side, up against the bulkhead. The expansion tank just pops off (pull forward, iirc) if you need a bit more space.

That is absolutely brilliant thank you
 
Update guys
No air in the system.
The pedal pushes to the floor. After a couple of presses it is firm again but after releasing it goes to the floor again.
The TC light also comes on when I press the pedal
Any ideas??

Did you bleed from all three nipple's on the master cylinder and in the correct order?
 
As mentioned Is usual with these vehicles when you get to point of giving up, few more bleeds and it clears. Never let the system go down. If you get air in the accumulator it won’t wanna come out
 
I think I know what the problem is. I ordered a pair or callipers and had been sent two left hand side ones. After fitting them the bleed nipple on the right hand one is at the bottom and I think this is causing an air lock.
I’m going to get it replaced and se if that helps

More than likely. 2 wrongs don't make a right as the saying goes
