No brakes the other day my brakes went out on my 1998 land rover there was no pressure at the brake pedal so i went and did a complete brake job including pads, rotors, and calipers. i bleed the system making sure there was no air in the brake lines but i still have no pressure in my brake peddal it just drops straight to the floor...could it be the hydraulic booster

Random abs engagement from faulty speed sensor.

You can energise the interlock solenoid, by you give a positive (+12V) lead to the RED and a negative (ground) to the black line at the transmission selector's connector.
If it works you should check the positive signal at the red.
It should be there if the ignition is on, brake pedal depressed, and the transfer box is in some gear, and the fuse 1 isn't blown.
At the black cable should be a ground signal if the selector in 'P' position.
If you give me an e-mail address I'll send the wiring.

The ABS problem, you have better to check followings.
- All the wheels bearings' play.
- are the ABS sensors at the deepst position? Knock some to that head (not strong) and they shouldn't move deeper.

your brake light switch at the pedal deeds to be adjusted or more likely, replaced

Your brake lights are not coming on and the vehicle is stuck in park it sounds like the brake light sw is failed or unpluged its usually located above the brake pedal on the pedal bracket it turns on the brake lights and unlocks the shifter when depressed.

... sounds like a broken brake line or broken linkage in pump/master cylinder ..... need more info, do you still have brake fluid in the reservoir?

Try this,sitting still,running,in park,hit the brake really quick and hard,
is the pedal ok? Then hit the pedal very softly slowly,and seeif it just fades to the floor .If this is the case the master cylinder is bad.
Also,keep in mind this vehicle had a twin cylinder,if you have complete failure of either end of the vehicle,the other half will still work but the pedal is very low,as you describe.
Check the fluid level,if only 1/2 the res.is full,that's the deal.

are you losing brake fluid? you may just need to bleed the brakes if you bleed them and have the same thing happening, you are going to need a master cylinder, but first check around at all four calipers and around the brake booster and master cyl, for wetness this means theres a leak.

Since many issues can cause brake failure and the brakes are very important to your safety as well as the safety of others, Please have your brakes checked out at a local brake shop.
Have you had the brake pads replaced lately?
Have you heard any strange noises when using the brakes?

with the engine off, depress the brake pedal 20 times. that should do it.

Jack ukp one side of car. Remove tire. You will see disk brake. Remove two bolts holding the caliper on. Remove the pads. Now once you remove the pads the piston applying the pressure will come all the way out. So you will need a 6" C clamp to push this back in when you replace the pads. You will need some anti seizing compound and some high temp grease to do the job right. Check the rotors, if glazed or smooth, have them turned at any maching shop or brake place. When using the c clamp to push the piston in remove the brake fluid cap and sipon some off, pushing the piston back in will cause the brake fluid to overflow. Replace the brake fluid upon completion of the job. Do one wheel at a time.
