You need pads, and rotors. You may be able to get the rotors turned. I'm not sure on a '99 if the rotors can be removed easily like they can on the 2001.

I just did a complete brake job last week on my 2001 with 140k on it. The rotors are original and had no noticible pulsing. I had them al turned for $70, and $40 for the front pads and $45 for the rear (OEM parts).

The pad are so easy to change I can do all 4 in less than an hour.

I did have an issue on one front rotor. The philips head set screws would not budge, even with an impact driver. I just drilled the heads off, and once the rotor was off, used a screw extractor. Piece of cake. I put all new screws in just for good measure, with anti-sieze on it.

If you have the rotors turned (or replaced), wash them with dish washing detergent and try not to touch the surface when you put them back on. You want the surface clean, and grease free. They will probably rust over before you even finsh the job. This is a good sign that there is no greas on them.

WARNING, you will probably need to remove some brake fluid. Wrap the resivoir with a rag around the edge in case it overflows. Remember, when you push the caliper pistons back in, the fluid will rise.
