Today I had a simple job (they all start out that way..) of replacing rear brakes pads on a 2012 Chrysler - Town and Country. I was asked to check it out because it began grinding when coming to a stop. After driving it and a visual inspection, it clearly needed brake pads.
See the grooves? No bueno. The pad had already started eating into the rotor from the metal to metal contact. Every vehicle is different, but this particular vehicle required a 13mm and 18mm socket or wrench. Jack vehicle up (USE JACK STANDS!!), and remove tire. Start by removing the two 13mm bolts holding on the caliper (the top and bottom bolt pictured).
After that, take out the pads by gripping and pulling straight out. Old pads.
Then remove the two 18mm caliper bracket bolts, and pull off your rotor.
It's recommended to resurface your rotors every pad change. This is done by taking your rotor to a shop, and the technician will mount it on a brake lathe which will shave metal off of the rotor to create a like new smooth finish.
Slide your rotor back on and reinstall the 18mm bolts and caliper bracket. Of course, tighten. Next you'll want to put lubricant on all contact points of the brake pads. Meaning it something touches the pad in that spot, put grease there.
Now your brake caliper piston needs to be reinstalled, BUT because the piston is pushed out of its bore, you need to push it back in. Normally done with a c clamp type tool, but because Chrysler is the work of the devil, these calipers have to be twisted back in. Grab you special tool and a 3/8" ratchet:
Line up the pins with the slots in the piston, and twist. Keep in mind: Some may be left handed thread.
After that, reinstall the caliper over the pads and install the 13mm bolts. Tighten. Then, step back and admire your work.
This vehicle also required a caliper replacement which I have saved for another post, so check back!
