So, I never hear anyone discuss or even mention “Driveline Lock up”. How many people even know it’s “a thing”.
Have you ever heard someone say that 4wd helps you take off from a stop faster on slipper roads but doesn’t help you slow down. Well that is not necessarily true. Vehicles have built in brake biasing. Most vehicles are biased to most of the braking done by the front ( Jeeps not so much). What Driveline Lock does is balance the braking equally to front and back.
What is Driveline Lock you ask. What it is, is the simple fact that when in 4wd the front and rear are now tied together by the driveline. If you had no rear brakes at all and only front brakes, when you hit the brakes the rear wheels would still stop you as if they had brakes on because they are directly tied to the front wheels. The rear wheels cannot turn any faster or slower then The front wheels. If you lock up the front brakes the back wheels will lock up just the same.
This “Driveline Lock” is demonstrated well on 4wd ATV that have independent front and rear brakes. There is also a warning sticker on most ATVs (my 2000 Honda Foreman has this warning sticker) indicating DriveLine Lock in 4WD affects braking. In other words if you are going fast in 4wd on loose Gravel and hit the rear brake only, the front will still lock up.
This just an FYI. Driveline Lock can help you slow down faster in 4WD but you have to be aware of it and how it works. It is also the same thing that can get you into trouble if you touch the brakes when you try and corner too fast in 4WD on slippery roads ..
