Re: disk brake at the back
Jack up the vehicle securely.
Remove the tire/rim
Remove the brake pads and the caliper, slide the caliper off to the side, do not remove the hose.
Remove the 2 big bolts that holds the caliper retainer bracket on, on the back side of the bracket
Remove the bracket
Tap the rotor to dislodge it from the hub.
Very easy to do.

Get a seond opinion always,make them show you whats wrong.Demand old parts back.Also negotiate.Price.Examole a Brake rotor that a mechanis will charge you $125.00 for actually cost the mechanic approx. no more than $28. or so.A $600. brake job only costs about 75 max in parts.Also you will pay a price that includes pads and resurfacing of the rotor.Average is about $129.95 depending on car.They will tell you you need new rotors and will charge for remove and install which is included and will will not deduct for not having to resurface the old one which is around 15 each rotor.I even seen some mechanics try an charge for a Caliper service to push the Piston back in.This is included because the new pads cant be installed without putting the piston back in its bore.Last thing.make sure that the guide pins are cleaned and new synthetic greased installed.this will keep the calpers from hanging up.Bottom line is know your car, and what things cost.One last thing There is not an honest mechanic out there,no matter how nice they are.
Chrysler has designed these for ease of service...remove the 2 bolts that hold the caliper in place...the rotor should pull off unless held in place by a thin metal washer on a lug bolt...remove and discard these retainers...most mechanics do not reinstall these...the rotors should be replaced along with the pads for best performance and smoothness...you can have the rotors measured to see if they can be resurfaced...(turned) you must push the caliper pistons back to flatness with the opening in order to install the new pads...after putting the rotor back into place on the hub...install the new pads and remount the caliper over the rotor...if you did not have to open any brake lines you do not need to bleed the system...inspect and fill the brake fluid reservoir as needed...do not be surprised that when first pressing on the brake pedal that it travels to the floor...it is resetting the pressure...and should pump up and hold pressure...test drive and reinspect/fill the brake reservoir again...Let me know if you have to open the system, I can help with bleeding instructions as needed...Hope this helps. Ceramic pads are the cleanest...sometimes slightly noisy until they warm up...
Your rotors should be fine but it also depends on who turned the rotors and how they were done.Considering the dealer replaced the pads they probably used a metallic pad which have been known to be a noisy .Id suggest you have a repair shop resurface your rotors again and install some ceramic brake pads.
If your rotors are good and fairly smooth, then a decent ceramic pad will work well. Just be aware that ceramic pads will require a slightly greater paddle pressure. They will last longer, dust up a bit less and will perform MUCH greater in stop and go traffic...
I suspect that 25 dollars per axle is a typical cost for good quality disc brake pads.
Most likely you have one or both front disks warped.
To reduce weight, disks have gotten thinner and warp fairly easily from heat buildup.
If the disk(s) are not too badly worn or too thin, it may be possible to resurface them to improve the flatness but in most cases, it makes better sense to replace them.
I would check Brembo to see if they make replacement disks for your car; I have had good service from them, better than OEM disks.
No you don't, you can have them turn the brake disk/rotor . Turning the brake disk/rotor is when you have the surface of the disk resurfaced by having a brake lath cut the high spots down.
The disk are cheap enough now that most will just replace the disk/rotor the same time they replace the brake pads. You can pick up performance drilled or slotted brake disk/rotor for almost the same price as the OEM disk/rotor.
Good luck and hope this helps, you can pick up the slotted brake disk/rotor at Auto Zone for a reasonable price and they will have the step by step instruction replacing the disk and if you like to just have the disk/rotor turned, they can do they there too.
