Im taking my car (a 98 ford contour) into a mechanic tomorrow, but I would like to have an idea of what the problem could possibly be, so I don't forget to say anything.

First problem: When I'm stopped at a stop light or going at super low speeds, there seems to be a clicking noise on the right side, in the front of the car. It drove good for a few days, but for the past couple of days I've been driving it like crazy. I tried to research the problem and I came up with the possibility that it could either be brake boosters or calipers?? Does that make sense? If so, what is a fair price for those to be bought and fixed? When the car is in neutral or park, it doesn't make the ticking/clicking noise. I did gt a belt replaced a few days ago, but wouldn't that make the noise in any speed or position?

There also seems to a noise when I go over bumps or railroad tracks and such. Its only in the back. Could that be struts?

Im not good with cars so I don't know if I'm even close to the right thing, thanks though!
