I hear if you have limited slip and your getting stuck and you see only one tire spinning you can apply a little pressure on the break and this causes both tires to engage and both will spin is this true?
very true....i find it is best to pump the brake lightly until you see it start to engage.
you can also use the e-brake on newer models.....when the brake light is on is usually all you have to push it in, but i push it in until i feel resistance and then i back off a hair!
open diffs apply power to the easiest wheel to turn, or the wheel with the least traction. If you give the rear wheels some resistance it will start to turn the other wheel.
The E-brake will apply pressure to both rear wheels. It's sort of a poor man's traction control. Traction control uses sensors on each wheel to calculate wheel spin. When 1 tire is spinning faster than the other, it applies the brake on that wheel. When doing so, this sends power to the other wheel due to the physics of the differential. Same thing can be done if you lightly apply the E-brake. It doesn't work wonders but, it can help you get out of a sticky situation.

no that's LS. an open diff is an open diff....it won't transfer any power b/t the 2 tires. how could it? there is nothing to control it.
muatang,
i was talking about using the e-brake trick on older vehicles....my truck has very few sensors and none of them are in the wheels. but i agree, it sure can be helpful but at the same time so can a full locker
An open diff sends equal power to each wheel as long as each wheel has equal traction. When one wheel loses traction, all of the torque is sent to that wheel. When you apply the brake, it "tricks" the differential into thinking there's equal traction at each wheel and sends some of the torque back to the wheel that actually does have traction. The brakes act exactly the same as the clutches in a limited slip differential. In a limited slip, some (not all) of the power is sent to the wheel with the most traction, so you can get through stuff easier. At some point, though, the clutches (or brakes) will not hold, and you'll get stuck.
A locker sends ALL of the power to the wheel that has the most traction, but lockers have strange handling quirks whe used on-road, and so aren't exactly the most comfortable things to use. They are much easier to live with in a heavier vehicle with an automatic.

Uhhhh, no. When a locker engages it sends power to both wheels, not one. Thats why you can be cruising around a corner and tap the gas and send your rear sideways...the locker engaged and caused both wheels to suddenly spin at the same ratio.

LOL. I think we're splitting hairs at this point. For example, on my Jeep, with Detroit fully automatic lockers, I can lift a tire. If you were insane, you could reach out and grab the tire and disengage it from the locker and the tire on the ground would still turn. Lock-right's are notorious for disengaging the wheel with no traction and the BANGING back into engagement when the wheel hits the ground or gets traction again.
When both wheels are on the ground, they both have enough traction to fully engage the locker, and both spin, creating a full loss of traction on the axle. LOL I think this is just semantics at this point. If you want full traction, a locker is the only way to go, for sure.

You could only do this if no power was being applied to the axle (and you had a death wish but it would be fun to watch). As soon as you step on the gas the locker will engage and both wheels will spin with equal power. If you can gas a locker and hold onto your tire you need to send it back where ya got it!
Jason, if you e-brake an open diff it will help apply some power to the traction side. It's like having equal traction on both axles. Or you could just weld the damn thing.
