Bill 12/27/2012Possibly rotors resurfaced or replaced. They make a compound you smear on back side of disk pads to help with squealing and chatter. Sticking as far as brakes stay on? You will need to check calipers for any leaks and buy a good synthetic brake fluid for bleeding the calipers after installation. A caliper piston depression tool that works would be another good idea, and some brake cleaner spray to remove oil from rotors.
Jimm 12/28/2012Check on-line for the many parts supply sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts. For example, they (RockAuto) list the front brake pad set from around $3.00, the brake calipers from around $11.00 (each), and the brake rotor from around $13.50 (each) for your vehicle.
