Outer Limits 4x4 Board

When I had the big lift put in, they adjusted the brakes as they should with the proportioning doohicky on the rear diff.

Since lowering it, I think my front brakes are doing way too much work as I havent changed the setting there..

Does anyone have measurements of the standard height of standard setup on the rear diff for the valve?

You lift the valve 1inch per inch of lift isnt it?

Thanks.

your rear brakes should be working more than front at moment ,the lower the rear sits the more rear brakes you will have.so taking lift kit out will almost have the rear locking up in gravel.

Make a bracket with adjustment.

Best way is to test and adjust. Measurements don't always seem to be correct for each setup.

imo the rear should do a far lesser percentage then the front. as you prob know a motorbike has in real terms about 80% front 20% (either by feel at the levers gauged by rider control or on abs single lever proportioning systems on the way too big ""motorbikes""), not sure what a truck should be , prob 70/30 or 60/40. you can just remove the spring and set it up manually by adjusting the screw at the valve

thats my first thought, but I wanna know what the std bracket looks like, and start there.

While I agree, the fronts lockup way before the rear feel as though they are doing anything.. maybe its just me..

I have come to the realisation that a 96 wagon can be a very different animal to series's before it, anyway I have some numbers to measure the adjustment from a Q I posted elsewhere when I did a small lift. I couldn't get the measurements to make sense on my 96 (might suit an earlier series) so I did a few emergency brake tests after each different setting until I was happy- no not happy GQ have crap brakes anyway, but good enough. All of my brackets are standard though.
If you want the numbers I will find them and post tonight or tomorrow.

Thanks, I just want a starting point to go from. appreciated.

Bogged here is a cut n paste of the reply.

When everything else is set up right, and at normal 'empty' height with the brake pedal depressed, the SPRING, from eye centre to eye centre needs to be 207mm long! When laden, the spring should reach 220mm in length when the pedal is depressed! You can move/adjust the bracket on the diff to set it right, and it really should only be moved when everything else including the master and rear wheel cylinder pressures and relationship have been checked and confirmed as correct!

Hope it works for you my measurements were too small to use the above.
