Hi,

I completely disassembled my brake system and will soon have to bring the car (Toyota Hiace LH50) to the inspection where the brakes have to function flawless. I adjusted the height of the arm to the settings in the manual but I know this valve can show many problems.

Basically when they are doing the brake test on the stand it will often:

a) not brake at all
b) block the brakes too fast

I know the load (cargo) in the vehicle of course will affect the results.

How can the home mechanic make the adjustments himself? I was thinking of driving down a gravel road, apply the brakes and try to assess how the rear wheels behave.

Any backyard, bush mechanic solutions? :)

Your method works. Just have to test.

Depending on how the vehicle is on a rack/stand will potentially effect rear brakes
