I have a 2002 ford explorer I replaced the front brakes and the make a grinding sound when applied. I know the brakes are installed properly and a little concerned about the noise. I noticed that the brake pads are beveled on the old set on both sides. The new set is flat all the way across. Could this noise be from the new pads being cut down by the rotors? I noticed there is a lip on the rotor that is in the same place as the bevel in the pads. Is this normal? I have never seen a rotor with a lip. Also it is a 4x4 if this helps.Please answer if you have any knowledge about this.

Rotors do NOT have a lip. Or, they're not supose to.
The rotors are worn down and should probably been replaced also.

It may make a difference that it is a 4x4 because this will make the front wheel bearings go out quicker. The real problem is that you never place a part on a vehicle with out comparing it to the old part. If it is different take both parts back to the parts store. If the old one is beveled and the new one was not, then you are cutting grooves into you rotors. These will now have to be replaced. The lip on the rotor is normal. Some mechanics want you to believe that it should be turned. This means to machine it back down to a smooth surface. Unless you allowed the brakes to were down to the metal I don't believe this is necessary. You are just shortening the life of the rotor. Jack it up and turn the wheel by hand. In most cases you can take the wheel of and find exactly were the sound is coming from. By the way the rotors aren't that as expensive and are very easy to replace.

The lip that you see on the rotor could be a result of the wear of the previous pads. The lip would typically be at the OD of the rotor, have a corroded, dark, apperance as opposed to the wear area that will be bright and shiny. You should have your rotors resurfaced to remove this lip. If you dont, the new pad might not fit the old wear pattern exactly. That could cause some noise. Also noise might be from the material of the new pads. Some brands, especially the longer lasting ones, have ceramic particles, or metal particals in the base material. They last longer but do make a "grinding" noise Frankly, I perfer the cheaper style of pads because of this very reason.

What you've done is what mechanics like to call a pad slap. You replaced pads with out resurfacing your rotors.
Over time, the rotors will warp, become grooved, or worn down by pads. I always recommend resurfacing your rotors after every brake job. It also will extend the life of your brake pads.
You can call around to your local shops and ask if they provide this service and all you have to do is remove them, and drop them off and it shouldn't cost more that $10 -15 for each rotor.
If the rotor is worn down to much, the shop will tell you when you come to pick them up, and you will have to buy new ones.
I'm almost certain this is your problem. Good luck and I hope this helps!

Sounds like you might be having some caliper issues. The caliper pins could be sticking causing the brakes to bevel. Other thing can cause this but most likely it's the pins. You want to take the calipers back a part and grease the pins. if this doesn't fix it then you should replace the calipers. Also your brake rotors shouldn't have a lip on them. They need to be replaced,

One thing with your brake fluid half full you need to check your brakes. You should only have low fluid level when you brake pads/shoes wear down unless you have a leak. When you go to change the pads and and before compressing the wheel cylinders you will need to remove some fluid from the master or it will leak out and all over. Brake fluid loves paint. If your are talking about your rear tail lights that are staying on and not your brake light indicator in the cluster check your B.O.O switch (brake on/off) it sounds like it is faulty and needs to be replaced.
