Will be replacing front brake pads and rotors and am wondering if i need to do anything to the rear braking system. The repair shop said rear brakes were out of adjustment thus putting more pressure on front brakes and wearing them out quicker. Is this an actual problem? or did they just want to get an addition $50?
If the rears are not adjusted right, it could be a problem. And they should be self-adjusting, although often the adjusters get frozen from rust, corrosion, dirt. To adjust them, you drive in reverse and hit the brakes. Every time you do this the adjuster should click-it has made one turn on the adjuster's star wheel. Do it a few times: reverse, press brakes; reverse, press brakes. If brakes were too loose, and adjusters were working, the brake pedal may brake better now-pedal may be higher when brakes are pressed. If not sure, peel off the rubber plug on back bottom of brake backing plate. You should see the adjuster star wheel. Use a screwdriver and see if you can turn the star wheel either way. If still not sure, take the brake drum off, pull the shoes off, and take off the adjuster for cleaning. They are very simple devices, only a few parts to them. If they need cleaning to free up, do so. Then use some high temperature grease, very sparingly, on the adjuster's threads. Put them back on, shoes, and drums, then do the reverse and brake again to get them adjusted. Should work great now. When you pull the drum off, you can check if you need new brake shoes- not likely, but check.
Good luck.

Since you are taking it back, have them check all the brake lines in front, and the wheel cylinder (if the back has drum breaks). Although you had only the front done, it's a good ideas to have them check the back brakes, and the master cylinder. Check your brake fluid before taking it back and make sure it's full, if so, you may just have air in the brake lines. If this is the case, either they forgot to bleed the brakes, or didn't bleed them enough.

The pins (slides) are corroded, you need to clean them up. Use Liquid wrench or some such to loosen things up, then have at 'em with fine sand or emery paper. When everything is nice and bright and shiny, brake- lube the slides, reassemble. Take your honey out for a root beer.

There should be an adjuster next to the handbrake lever. You may have to remove some trim to see it but it is in the general area of the lever.

Ok simple
Place the car in park set the hand brake chock the rear wheels with a brick or a rock so the car does not move.
Now loosen both front tires and lift the car up to a good comfortable working height. Next remove the wheels and set them aside its pretty simple if your just going to replace the brake pads only, You will see something called the caliper it looks like a clamp it will be held on by two screws they can be special screws or simple bolts you remove both of them. now the caliper (clamp) is off there will be a piston that will be pushed very far out you must use brake spreader or very large pliers or a C clamp to push that piston all the way back in. You do this to both sides than once your done with that you will get your new set of brake pads and match them to your old one's make sure there the same and than you install them right where the old one's are with the caliper off. You put it back on over the brake pads clean up the entire area with some brakleen brake parts cleaner. than attatch the caliper with its two bolts and tighten them tight and place the wheels back on the vehicle set it down and remove the jack stands pump up the brakes till there hard BEFORE attempting to drive and that's it your done go for a test drive check over your work 2 times before you set the car down.
