I have a 1998 Buick Skylark. I had an engine put in it almost three months ago.

(1998 Buick Skylark)
in Saint Louis, MO on January 18, 2012
Before the engine was put in the car it sat for two years. I replaced front brake pads, rotors, rear shoes, and drums replaced three months before the engine went out. Now I have a problem at times, when I apply brakes, a clunking noise seems to come from the back passenger side of the car and then, the car bounces up a down. I've had two mechanics to tell me what they think is wrong with the brakes:
Mechanic #1 - Told me that he test drove the car, took the wheels of, saw that there was alot of rust/brake dust, sprayed the car with some type of brake cleaner. After driving the car less than 5 miles, the noise is back. I took it back, the mechanic does the same thing as the first visit. Again shortly after driving it, the noise is back. The third and final visit the mechanic tells me that the noise is coming from the front of the car and that he needed to "turn my rotors" and "adjust the front pads." This didn't sound right to me. I thought that you "bleed the rotors" and "turn the drums."
Mechanic #2 test drove the car, took the wheels off the car, and told me that one of the back brake shoes were cracked, there is a leak from the wheel cylinder, my drums need to be resurfaced or replaced, front pads, and rotors all need to be replaced. They said that the problem with the clunking noise and bouncing is coming from the rear of the car. They also said that the fact that the car sat for two years could have made all of these parts "go bad."

I'm just overwhelmed with this information. Can you give me your opinion. The engine replacement cost me $1,380. Mechanic #1 - I don't believe is telling the truth nor do I feel is qualified to do the work.
Mechanic #2 - I believe as for as the broken brake shoe is concerned and that there may be a leak, because he showed me the wet area & the broken brake shoes. I find it hard to believe that everything else has to be replaced. This estimate is close to $800.

i agree with number 2. what he said makes perfect sense.
rotors cannot be bled. they are metal and need to be replaced. front pads cannot be adjusted as they adjust them selves.
stick with the second guy.

Mechanic 1 sounds like he did some work on the car and is tired of you coming in so he recommended everything to get rid of you. Also known as robbing you if you want to look at it that way.
Mechanic 2 is telling you the truth. The leaking wheel cylinder causes the brakes to grab and not slide inside the drum. This causes the rear of the car to dip in the rear. The brake shoes are craked due to high temperatures. The brake shoes do crack, I dont know why. He wants to resurface the drums because of the leaky wheel cyinder which is a common pratice and nothing to be concerned about. As for the front brakes not being able to see them i couldnt give you any advice. He may have recommended them due to a pulsation in the steering wheel while braking or they might just have to be replaced. I dont know how he would have felt this pulsation with the brakes grabbing in the back so they are probably worn. I recommend getting a second opinion on the front brakes first.
