When servicing the rear disc brake pads, first lift and support your vehicle, then take off the wheel and tire assemblies. After squeezing the caliper, tilt the top of the caliper out of the adapter so the top doesn't hold the hose to the assembly. After supporting and hanging the caliper, take out the inboard brake pad from the caliper adapter. For installing the calipers, use an old brake shoe wedged in the gap as you put the pistons in the caliper bore, with a C-clamp above the brake shoe and piston. Clean the caliper holder and its anti-rattle springs, coat them with Mopar brake grease and install the specified anti-rattle springs, since they do not work with any others. Then, set the inboard brake pad into place in the adapter and then insert the outboard brake pad. Over the rotor and below the adapter, try to slide the top of the caliper into place first, then press the bottom onto the adapter and attach it. Lower the car, fit back the wheel and tire assemblies, then press the brakes several times to make sure the calipers and brake shoes stay in place. When finished, add some more brake fluid to the master cylinder, as the makers suggest.
