brake problem
well last night when i had posted this, i was in the middle of checking out the rear brakes. the pad wear was normal, nothing seemed unusual. i had someone come over and look at them with me and they suggested i lube the pins so i did that. otherwise i just put them back together. the noise continues but it isnt as bad as it was originally. the vibration when i come to a stop is no longer there.
well originally i hadnt lubed the pins so i did that last night and it helped but it isnt completly gone. what do you mean by turn the rotors? just spin them? if that, then yea i did that.

Ok, I was under the impression that you had already done a brake job on the rears when you first posted, but now I understand you had not. The fact that the pins needed lube and that they had been run that way previously (to the point of causing vibration) would lead me to consider if perhaps your pads and rotors have worn irregularly, DESPITE the fact that they may appear to have some usable thickness left to them. If the pins don't allow the caliper to move freely so that it always centers around the rotor, you can wear one pad more that the other, and one ride of the rotor more than the other.If it's bad enough, this CAN cause vibration that may not be correctable without a new set of pads and machining (or "turning") the rotors.
so i changed the brakes yesterday all of em, changed the fronts first, drove it they were fine. then i changed the rears. when i went and drove it there is this weird noise coming from them. when i apply the brake and slow down they make noise, like a deep 'slowing down' noise so to speak and just as i come to the stop the rear of my car vibrates. any ideas?
Ok, so I guess I'm still confused by exactly what you mean when you say "changed" the brakes. Generally speaking, if you put new pads on, it is best to also have the rotors "turned" or machined at the same time so that you aviod nagging little vibrations and noises like you are describing. It doesn't take visible scores and grooves in the rotor surface to cause vibration; it can happen just from uneven pad transfer from the last set of pads, especially pads which you said were used with poorly lubed slide pins. My guess is that's what is going on here, but if I were you, I'd stick with your dad to see it through; sounds like he'll have a pretty good handle on everything.
