Extended Brake Hoses + Load Proportioning Valve

Hey, just did a 2" lift on the Hilux - all seems good except I think I really need extended hoses. It's all good sitting on the flat, but I can't jack up from the body without the hoses pulling tight - haven't even jacked it up the whole way as it was getting real tight long before the wheel started to lift.

Where do I go for this - I see snake racing in aus do them for $180 for front, 90 for rear, but that's going to take a while to get here and cost even more to ship. Is it legal to get them made up? Who can do it? Would that be cheaper or cost even more?

Also, what have other people done to modify the brake bias valve for their lift - and what is legal? Just took it for a quick drive and it seems like I'm lacking rear brakes i.e. leans forwards and then starts to brake. I assumed this would probably need modding, but still haven't worked out what to do - if anyone has a picture of the valve and the arm going to the diff it would be greatly appreciated as I'm not sure if the connecting arm on mine is a bit bent out of shape.

You should be able to get new hoses made up cheaper than that at any local brake shop.
Just take your old hoses in with a measurement for your new ones. Pay to flex your suspension and work out the lengths you need.
Another option is to move the mounts on the chassis in the front, where the hoses attach to the hard lines. Cut the brackets off the chassis and move them down and re-weld them, make sure you remove the hard lines before cutting and welding

As for the proportioning valve, if your rear brakes were fine before the lift all you need to do is make a bracket to lift the arm off the diff the same amount you lifted the suspension.
There is a bracket that bolts to the rear diff with two bolts, it has a pivot above it. Unbolt it from the diff and make a bracket to lift it. I just used a piece of 25x3mm flat steel. Drill two holes through it to bolt to the diff where the bracket used to be. Then drill two more holes further up to lift the original bracket up the appropriate height. You can play with the height a bit to improve braking, as your suspension would have sagged from new height.

I went to BNT with a sample and found a hose with the correct ends but longer.
There are lots of toyota style ones.

Got this one for the front.
Then used the old front one and added it into the rear one.

So only needed to buy one hose.

Note, the front hose was really long and would rest on the diff housing, WOF man wanted it protected from chaffing. So I put a big open wound spring arount it.
Can still see the hose for WOF and stops it rubbing.
