Raised rear = adjust load valve

[TOMUCH]

David, you should have approx 7 - 9 clicks...according to toyota.. Cheers TOMUCH

[david allan]

ok guys, has anyone resolved the LSPV concern that we have been having after we raise the rear.

I have the OME rear leafs, approx 30mm lift.

I have wound the nut all the way up to the top & also reversed the nuts around (small nut on top).

Got no idea it is to much or not enough.
Toyota nor ARB cant help thsi matter.

Anyone come to a conclussion

[Glenn k]

i have come to the conclusion to just live with it.

i have done exactly what you have done, and i can say that it help a little tiny bit i suppose, the next thing i will do is get better quality brake pads when these wear out, that wont be for as while but...

i really dont like the thought of messing around with the brakes to much
Glenn

[david allan]

how much lift in the rear do you have glenn ?

there is no more adjustment left for us as we have reversed the nuts aswell. The only thing would be to extend the rod

[Glenn k]

i got about 35mm in the rear

i am not going to extend the rod, i dont want to go there...

I havent touched the LSVP and got a 50mm lift in the rear. The brakes seem perfectly fine. Although when I have a bit of a load on the springs compress and put more bias to the rear which helps it anyway. I find the bias preety good on mine.

yeah it seems to help the more weight you have in there.
i drive around empty all the time so i notice that they dont work very well, but when there is weight in there they seem better...

david just go and get a few bags of cement and put them in the back of your truck, fuel figures will be up to shit but at least the brakes will feel better...lol

Glen, did you get the med or heavy rated ones in the rear.

And also just for comparision what measurment do you have in the rear from bottom of rim to bottom of guard (eg 820mm)

Skog, you shoud have a try and adjust the LSPV abit & see if it makes a difference especially that you do carry alot of weight with the trailer. You might find that by adjusting the LSPV you have better braking effect.

[Glenn k]

i got the medium springs and it measures at exactly 820mm both sides

Guys,
Anyone with OME suspension fitted, who had it fitted by ARB should go back and question them about what brake tests they did as part of the fitting process/charge. Just checked my price list and the text in the suspension section for a Hilux states "Fitting Charge Includes Wheel Alignment and Brake Performance Checks". I know that the brakes are not that crash hot to start of with, but IMHO they should be no worse after the aftermarket suspension has been fitted than what it was beforehand.
See what they come back with.

I have not checked the brakes on mine yet. All I know is that they are a lot better than what I had on my old LN106.

When I was an Apprentice, the minesite where I worked had a lot of 2WD LN65 hilux's and we were continuously having problems with the back brakes being too aggressive, especially on hard packed haulroads. Had to adjust them off by shortening the adjustable link between diff and arm. A small adjustement on them seemed to make a lot more difference on them than it does on the later models.

Have a look at the training material on the following link. It is from Toyota USA but the principles would still apply to our vehicles. Contains a lot of good info. Hope i have done it right

I actually asked ARB about this originally & they said they have tested the brakes & it seems to be fine.

Thats fine in ARB's point of view

[Rich]

Never mind.

[david allan]

i just adjusted mine all the way to the top with the bolts reversed & it seems fine now

[david allan]

how do you know if you have adjusted it to far.
Is there a max that you can adjust it so the rear brakes dont become too aggressive

reason im asking is that i got an approx 30 mm lift & have adjusted it all the way with the bolts reversed.

This makes the vehicle brake with no prob now.

But im wondering that when i do load the vehicle up which makes the rear drop, which should put more bias on the rear.
But how do you know if the rear are to aggressive now coz i have adjusted it all the way.

Does the vehicle have a max rear braking force so even if its adjusted to high, it will still apply the max allowed rear braking

[Rich]

I have adjusted mine all the way to the top and reversed the nuts.

I was 4WDing last weekend and I decided to lock up my brakes on a dirt road and test them.

The front locked up (and activated ABS), the rear did not.

So obviously, I haven't adjusted mine too far!

The horizontal rod going across above the axle to the LSPV will only go about another 20 MM above the top of vertical rod from my diff...so not much adjustment left for me even if I was to extend the vertical rod.

Has anyone else checked how far theirs will go?

Rich.

[david allan]

rich

you say that you can go only an extra 20mm above the rod, but some guys here have actually extended their rods & am sure it was extended above 20mm.

[jamiecracker]

i extended my rod and it helped a bit but still not happy with the brakes

[david allan]

how much rear lift do you have.
Also how much did you extend the rod by

[Rich]

David,
Yes that is confusing me also. Some people have extended the vertical rod upwards, but mine only has about another 20 MM higher to go...so no point extending, there will be no play in it for when I put weight in the tray.

I have actually asked that question (I think earlier in this thread or another about the same topic) but didn't get any answers.

It is silly having such a set up when we have ABS in the SR5, they should just always give max braking, the ABS will stop it locking up.

Rich.

[david allan]

bringing this topic back to the top.

Anyone got any more ideas/thoughts.

Has anyone actually adjusted it to far causing the rear brakes to become to aggressive
