traction during off road driving.
We all know how important traction is during off road driving.Some time or the other we have had our wheels spinning hopelessly and then we are stuck.Of course there are a lot of driving aids like locking diffs., l.s.d. , etc.
but apparently there is also a simple way to overcome this problem.the very first tempo trax ( 2 wheel drive , soft top and short wheel base) came with this.they called it independent hand brake on each rear wheel.their theory was simple when one wheel looses traction apply hand brake to that wheel , immediately that wheel will stop spinning and power is transferred to the other wheel.has any one tried this ?

Sounds good to me. Did anyone tried this method, if yes then what was the outcome of that.

Yeh ,although it works, the wheel that is not being held on by the brake will then be revolving at twice the speed its normally supposed to(rovolution is doubled by differential action when one wheel is made to stop). So not only will it give you a nice jolting jerk, but the moment this wheel lands on a hard surface, then all the engine torque, and the additional torque gentrated by the inertia of the revovling wheel(which undoubtly is going to be quite fast if you were pulling out of something) will immediately act on the other braked wheel, forcing it out of the brakes hold, and resulting in a very fast depleating brake shoe liner. On the other hand, even if the brake is strong enough to still get a hold of it, then all the torque generated by the inertia and the engine torque , plus the jerk when it immediately gains traction, will act on just one thing that comes it between, and thats the axle. If you got a WW2 jeep, then its very likely you are going to break that AMC full-floating axle shaft(the side it was braked on) and that will lead to a very expensive hunt for spare parts. And if you got a later jeep(till the Cj6) that has the semi floating Dana44's, then its very likely its going to break the axle, shearing the carter key and breaking right where the 2 peice axles are joined, which even otherwise are quite a weak set, and you then would then probably be looking at about Rs3000 worth of job atleast.
