Ok...first off, describe the grinding. Is it a grinding like metal to metal, or is it a squeaking like the pads are worn out? If it's the squeak, when the pads were replaced, did you coat the pads with an anti-squeak lube? This could be the problem. If not and it a metal to metal grind, check the pad location, are they installed correctly? Do you see rubbing marks on the rotors? Final question is what type of pads are they?
There are different types of pads on the market, one is a cheap organic type, the other is a semi-metallic, and finally a ceramic type. The organic type is cheap and causes a lot of brake dust, but you shouldn't get any kind of noise until the pads are around 2/32 in. Then the early warning tabs will be rubbing against the rotors giving you a squeaking noise.
The semi-metallic pads last longer then organic pads, due to the small pieces of metal encased within the organic material. They give off minimal dust, but because of the metal in the pads, tend to also squeak if when there installed don't have a anti-squeak lube coated on the back side of the pads (the side facing the calipers).
The ceramic pad give off little to no dust, but because of the composite material used in the production of the pads, they need to be installed like the semi-metallic pad and have a coating of anti-squeak lube.

I had the same problem with my 1997 Grand Cherokee and it was the dash mounted automatic light switch. The problem was also solved by turning the headlamps on manually.
the answer is here www.installdr.com I had the same problem.
There is a dead short to ground in the circuit.
You have drum brakes on the rear.
I will assume that you are dealing with stuck rear calipers which is very common. if this is the problem replaicement is required. on the other hand in order to push in the calliper it acully needs to be turned or scrued clockwise for it to be retracted to install new pads.
well i read somewhere that 1993 jeep grand Cherokees with the 2.5l had a terrible engine problem where it would vibrate from either the engine mounts not installed properly or another factor. this is the only year with this problem. if it doesn't have a 2.5l, idk what ur problem is. P.S. they stopped putting the 2.5l engines in the 1993s when this problem arose. buy another year or engine. If it is shaking while driving, and you feel it in the steering wheel, check balance on the wheels, then replace the steering stabilizer, if it is going out you will be driving along just fine and then it will start to shake like crazy and wont stop till you use the brakes.
What about 1993 Pontiac drum brakes, please be specific.
