if you are capable of removing your tires, im sure between the techs we have on here you could be talked through a few simple checks for your front calipers. but first thing i want you to do.
go to a road with minimal to no traffic. drive at 50km/hr. down the middle of the road, this is to take away the road crown affect. (road slopes towards the edges). take your foot off the gas so you are coasting. and slowly apply the brake and take your hands OFF the steering wheel. your vehicle should come to a complete stop in a straight line. after you have done this. do the same thing only apply your brakes a bit harder and then slowly accelerate again with your hands OFF the wheel. if you apply your brakes then release them and hit the throttle gently accelerate.. your vehicle should stay straight. if you have a sticky caliper or something jamming up your brakes the second test will tell you what side. if your steering wheel jerks to one side or the other then you know its the front. if your vehicle pulls to one side but the steering wheel doesnt turn too fast then you might have a problem on the side it travels towards in the rear.
i hope that will help you with your start. OR you could take it to a shop that offers a Free brake inspection. but just be careful cause the inspection is free, but the problems they find are not. so make sure you ask for all your damaged parts back. if they need to return them for a core charge then ask to see them before they box them up.
