Macca,

Thanks for the pictures.

hey
I talked to Toyota & they told me not to adjust it myself. They said they need to look at it with their gauges etc. Am still thinking about doing it myself to have a try.
Has it made any difference to the people that have a approx 40mm lift, if so how far up have you gone

[david allan]

hey guys have just completed the TO MUCH Brake test and tried moving the nut up & down.
I even put the big nut on the bottom of the rod & there was no really difference when the vehicle has jacked up.

I then went for a drive with it wound up all the way with the small nut on the top, i think it could be to aggressive, so I will wind it all the way to the top with the big nut on the top of the rod & will see how it goes for couple of days.
Talked to ARB & they said they have never had to adjust it (this has to be bullshit right).
Might go to a brake specialist & see what they say.

[Stu-k]

Most of what arb does and says is bullshit

[david allan]

just came back from a test drive & it does stop easier.
Will see for a couple of days & might even put the big nut on the bottom to adjust it even further.

Will the large nut on the top the most you can adjust it is approx 10-15mm. My lift was approx 40mm, so I might rverse the nuts to get an extra adjustment

thanks for all your help guys

Now it's all clear.
Since my lift i noticed that braking had changed but never got around to doing anything to check it out.

Just had my brakes done last week so I thought I'd be swwet again.

On the way up to Inskip the other day fully loaded for a week of camping, hit the brakes in the wet and just locked up for a second (sr no abs) thought it was weird cos it doesn't usually.

Then after spending the 1st night in the wind and rain with even stronger winds (up to 90kmh) expected, we packed up to come home.

Not 2km down the road in the wet, the convoy reached a round about, normal speed, everyone braking.

We locked up in a big way. l let up on the brake then tried again and locked up again. No other choice but to shoot through the round about in the wrong lane. Good thing no other traffic.

Was gonna post some Q's about this but now i know the front brakes have been doing all the work and the week load of gear in the wet was just too much.

Thanks fellas, I'll be checkin mine out today.

Guys a sure fire test is to get the Toyota to test the pressures at your next service... This is a pretty simple test.. I personally would adjust the rear brakes myself until I was happy with it, then take it in for the final check... just for reassurance... if the pressures you set are too high, Toyota should adjust them down, however if the pressure is too low.. and there is not enough lenght to adjust it up.. then Toyota will not be able to do it...

I imagine for you blokes who have had your front brakes do all the work a close look at your front pads may be required.

Not trying to teach people to suck eggs but there's always one.... lol

Yep replaced my front pads just last week at 70,000kms not too bad I think... must go adjust it up and make my rear brakes work a bit more

I have the Diesel Auto with an ARB OME lift (medium springs in the rear), which is apparently 45 mm lift in the rear.

I have experimented and have now ended up with it all the way to the top, including reversing the bolts around. I think it has just started to take effect as I notice a slight increase in braking, but it is still not adjusted quite enough, another 10 - 15 mm should do it, the problem is that I have no room to adjust it any higher - and I don't have a welder....

Macca, is that some sort of extension you have added to get extra adjustment - and where did you get it?

Rich.

PS happy new year everyone.

[Rich]

Perhaps you can buy eyebolts similar to the one used - just longer to allow for extra adjustment - and replace it??
Has anyone done this?

[Dluxv6]

Toyota simple adjust and pressure test is not simple(Mechanic and 5-6 hours labour)Gold Coast Prices.
buy threaded rod to suit(cut to you desired length)ie sufficient to adjust bar up) and extra nut.thread new rod halfway into original long nut and screw back onto existing rod and tighten, re-install and use extra nut and original nut to secure and tighten down. am running 3 inch lift and brakes are fine

[Rich]

Thanks for that Drew.

[Macca]

Sorry Rich, Been away for a week. The long nut I used was from a hardware store, used to join 2 lengths of threaded rod. 8mm thread.

[Rich]

I have a question for you guru's out there:

I just went to take the rod off (so I could take it to the hardware store and get an extension piece to allow for more adjustment upwards) when I noticed that the adjustment reaches it maximin about 20 mm above the top of the rod.

I noticed this when I lifted the fitting off the top of the threaded rod and it would not go any higher than about 20 mm from the top of the threaded rod. (reaches its end-stop)

So, there is probably not much point in extending the rod as you guys have done, as it seems I am close to maximin adjustment already??.

It doesn't really make sense, have you guys got the same problem? Are you running close to the max height it will go up?

Rich.

Rich
Mate of mine (brake shop owner) only suggests you raise the bar equal to what you lifted rear of 4by.Rear brakes may get to aggressive if adjusted to far

that sounds pretty close to the mark as one end is attached to either side of the suspension lift.
i haven't gone there yet i might be wrong big time ?

On my lux I set the hieght at the max (the horizontal rod is high as it will go)
There is plenty of flex in the rod.
Towing the camper in the recent rains was not a problem, locked the trailer wheels occasionally in varying conditions but had total control in the lux with lots more braking for less pedal.
If it was not such a hassle, I would take the valve off completely as mine has canopy, drawers, liner barwork, e.t.c. and I like the extra braking.

[troyco]

WOW - thanks for the heads up on this.
I do not have lift but have air bags, doing the test, up to 25 psi is ok after that the brakes start to being less effective, at 50 psi there is nothing, no stall no stopping the wheel. Great, when loaded and at 50 psi no rear brakes!! I will try an adjust at 50psi and test again, I do not think I would need an extension with no lift but a tweak is necessary. This could have been a disaster for any of us , Thanks again
cheers troyco

[Rich]

The thing is that I havn't raised it by the height of my suspension lift yet....

My Lift was 45 mm in the rear and I reckon I have raised it about 20 mm so far, and if I raise it another 20 it will be at its maximin.

Weird. I am not really sure what to do from here.

Rich.
