I'm guessing your average shadetree mechanic could not adjust this since it must be difficult to measure brake fluid pressure it effects the truck by making it think there's less weight on the rear end there fore needing less breaking to possibly avoid a lock up situation it therefore will proportion more breaking effort to the front of the truck and over time if uncorrected will lead to faster wear of the front brake pads and rotors ask me how I know Oh well it was a good excuse to do the front brake upgrade on mine anyways but i will be dealing with this over the next couple of days I have the factory service manuals but don't have the funds for the sst to measure the break pressures basically the idea is to have the sensing arm at the same position as it was before the lift and that should eleviate this mis proportioning of brakes.
The result is more braking at the rear which enables increased traction at the tyres due to the extra loading being applied.These valves are often found seized and usually only picked up on when it comes to the MOT.Please note: This valve has a 3 metal brake pipe setup, it's worth checking your original valve also has the same when replacing a valve.
