Warped rotors... New pads?

Hey,
I had my front rotors machined because they were warped. Ever since I had that done, the front left brake now clicks when I stop. The harder I press, the louder it is. I know its the brakes because I came to a full stop using the tranny, and not a single noise came from the wheel. When I use the brakes, it happens. Also, it usually doesnt happen right away. Its like the brakes need to "warm up" before they start making the clicking when stopping.
I was going to buy brake pads, but I wanted to see what you guys think is making that noise. Would the pads be shot because of the warped rotors? Now that the rotors are flat, the pads are "uneven"? Any one had this happen? Thanks a mil.

Disassemble and inspect. Sounds like something is loose. Pads probably will not help. Good Luck.

it does sound like something is loose, but generally you should change pads if the rotors were warped. i just changed both at the same time when i did mine.
not sure what the deal with the click is though

You would usually want to change the pads with the warped rotor, depending on how warped the rotor was, because it would take longer to seat the old pads to the new rotors.

Never had a problem with old pads and new rotors. Here in Florida we get rain every day so rotors get warped pretty fast. Not doing much performance driving though.

I did take off the wheel to try to change the pads. However, the 2 lil bolts holding on the caliper were too tough to get off. I cleaned the brakes and inspected them the best I could (Im not a brake man, but I tryed). Pads did look good. They now don't click as quickly. When going somewhere, sometimes they dont even make a sound now. But, once it starts, it gets worse. This makes me think that the pads are fine. Ill take the wheel off again my next day off (God only knows when that it!!). Any idea what can be loose? Thanks

Sounds like your caliper is sticking. The sound you hear is the pad on the "stuck" side rattaling around. When you cleaned it you got it part of the way freed up. Just keep at it. Good Luck.

Sounds easier said than done, right? How can I free it up? Just keep spraying brake cleaner? Stick a screw driver in the pad and pry? Ill try some stuff on Tuesday. Anyother ideas?

Anyone? I'm cleaning them again right now. Any other suggestions on how to "unstick" it? All I'm doing is spraying brake cleaner and getting high off it... lol. Any help? Thanks.

I found this:
A common problem with SE-R’s and cars with floating type calipers in general, is that the pins that the calipers slide back and forth on can become corroded or even sometimes bent with use. The pins are protected by a rubber boot that often becomes cracked and oxidized with heat allowing water to enter which corrodes the pins. I am not sure how the pins can become bent but I have seen that happen also.
Corroded or bent pins results in the caliper binding as it tries to slide back and forth as the brakes are applied. It can also prevent the brake from releasing completely. You can tell if the pins are sticking by looking at the pads. If one pad is worn significantly more than the other than you most likely have some binding. If you replace your pads and the brakes drag, or if the car has uneven side to side braking, the first thing to check is the pins also. Another symptom is that your brakes are really hot all the time and your pads wear out unusually fast for no apparent reason.
To inspect your calipers, move the caliper on the pins by hand, it should move freely. Inspect the rubber boots on the pins and replace them if necessary if they are cracked, oxidized or missing. Cars that run track events are prone to this as track driving really gets the brakes cooking. The high heat causes the rubber parts to deteriorate quickly. It is a good idea to grease the pins with high temperature disc brake grease every time you service the brakes. If the pins are bent they should be replaced immediately
So this means that I need to get my brakes replaced then, right? The pad is "floating" back and forth, making the clicking noise occur then. So, this isnt bad then, is it?
