It most likely will, grand Cherokees didn't change much those years. As long as they are both grand Cherokees, and as long as one isn't a Cherokee and the other is a grand Cherokee.

You may have a brake booster that is leaking. The diaphragm may be busted. You will need to remove the brake booster vacuum hose and do a vacuum bleed down test. If the booster will not hold vacuum it needs replacing.

You need to inspect the brake pads/shoes and have the brake system bled. The soft pedal is air in the brake system. The fact that you are hearing air makes me suspect you may have a defective brake booster. Have the power brake booster vacuum diaphragm inspected.
Sounds like the power brake booster has a vacuum leak.
