D2 td5 auto SLS + Towing questions

Hi all my disco keeps dropping all its air on both sides some times while driving sometimes after I've just parked, ive fitted new bumpstops on the rear (the old ones were just tin plates) and new hight sensors, just got a job lot on flea bay compressor, air bags, hight sensors, and slab thingy. So my first question is how do I release all the air out of the system manually to change the parts?

I bought a twin axle caravan weighing in at 1600kg but my disco feels so sluggish like its struggling to tow it, and when I reversed it into my dads it struggled and felt like I was trying to push a pallet of bricks, the caravan it's all checked out and in perfect running order so I know it's not the van that's causing it. So my second question is what could be wrong with my disco?

Thanks in advance for any replys

What's it like solo?

With a 4000kg train weight, it's got a tiny 34 BHP per ton power to weight ratio, so it won't be exactly sprightly.

My Freelander 2 tows 1600 kg with relative ease, but it's considerably more powerful, with less body weight to pull about.

Does it have over run brakes that are being applied when reversing?

Yeah solo it's fine plenty of power, I and picks up speed well, at one point last year it was dipping revs on the same slip road every day but not changing gear but that seems to have stopped

It does have an alko braking system on it that's engaged by the tow ball with pressure and it's all been checked out and working fine, I pick the van up with a friends car and it pulled no problem, but when I pull it with mine it just doesnt want to go
