try cleaning the rotors, I know exactly what u mean, I have this same problem, I slightly touch my brakes and they grab real quick. I would try to clean the rotors with some brake parts cleaner and c if that helps.

Gunsnroses....

What kind of pads did you have installed and did you turn the rotors, replace them or run the old ones without turning??

Also - have you done anything to the calipers??

First check the condition of the rotors on the front. You should be able to see the outside surface of the rotors throught the spaces in the wheels. You might need to remove the wheels to see the inside rotor surfaces.

If they are scored, the front pads might be worn down and come loose from the plates. Could be a sticking caliper too. That would prevent the brake from applying gradually.

Check the drum brakes on the back by removing the wheels and looking for loose hardware inside the drum. Depending on who did the job, it could be that they got the shoes mixed up too. Should have one short lining shoe at the front of the backing plate and a long lining shoe at the rear of the backing plate on each side. An mixup there will mess up the servo/selfenergization action when you step on the pedal. Check for fluid leaks too. It could be an axle seal or brake fluid if they didn't check the wheel cylinders close enough.

Wheel cylinders can leak after brake jobs because the sealing cups are repositioned inward slightly when new shoes are installed. That puts the seal lip on a corroded surface that allows fluid to leak. Replacing the wheel cylinders is the only fix. They should replace the shoes as well if they are contaminated with any fluids as the fluids break down the bonding materials in the shoe when heat is applied from brake applications. No matter what they tell you, the shoes are NOT cleanable when contaminated!!!

It is still less than 90 days from the install. You might inquire about some warrenty.

Just a couple of things that come to mind...... Gives a place to start though. Could be something a lot simpler too.

ONE MORE QUESTION - Does the jeep pull to one side when the brakes are acting up??

good luck

If there is no pull, then it is not "serious" yet but a good thing to check out before the warrenty is over or it gets worse.

is there always a 90 day warranty with the dealership?

I've seen 90 day warrenties and some shorter and some longer. Give them an anonamous phone call and ask about the shop work warrenty without telling them that there is a problem. Just make it like you are thinking of getting some work done there.

If the pads you used are the inexpensive type, They are not consistant. They lose their friction properties partway through their life. Always buy top quality brake parts. Worth it all the way.
