Re: Working on Brakes (especially Rear Drums) - TJ
On really steep stuff, I have had to use my e-brake on many occasions to
help in those kind of situations. Not just with Jeeps, pickups were way
worse.
Others have posted about not being able to lock the rears at low speeds.
One Jeep out with us actually lost his rear brakes and wow what a
difference. He literally could not stop the roll back on a ravine
climb. He nailed a tree 3 times in sliding backward and we had to drive
around to give him a pull from the front just to get him out of there.
It is worth inspecting though.

Hmm....so, with the limited slip....the whole brake trick to get rid of the

Re: Working on Brakes (especially Rear Drums) - TJ
It works in both 4wd and 2wd. This technique works with open axles too,
it's been in use since Model T days when most vehicles got stuck more due to
there being more unpaved roads back then. :)
