Q: How to Maintain a Rear Brake Caliper on 2003 Dodge Caravan?
A: The first thing to do is step on the brake pedal past its initial inch of travel, then hold it steady with a brake pedal depressor to keep brake fluid inside. Following that, lift the vehicle and withdraw the back wheel and tire assembly. Remove the brake hose from the caliper by removing the banjo bolt, throwing out the trio of washers that come off together and then removing the caliper guide pin bolts. In order to remove the rear caliper, rotate the front of the caliper up and then pull the rear away from the adapter. If you need to, unclip the brake retainer, then just pull the rotor right off the studs. When you disassemble, hang the assembly from a wire hook, take out the brake shoes and insert wood to prevent dirt from entering between the piston and fingers. Gently press the brake pedal to move the piston out, then keep it held down to keep fluid inside the system. Take out the brake fluid flex hose and use a vise with protective holders to secure the caliper. Get rid of the piston dust boot, withdraw the piston seal with a suitable soft tool and inspect the bore at the same time. Wash the caliper with fresh brake fluid or Mopar Non-Chlorinated Brake Parts Cleaner to be sure not to harm any rubber pieces. Examine the caliper for any leaks, harm to the dust boot and the subsistence of dust boots; if there are any, adapt the caliper with new seals and dust boots. When installing the new components, dip a new piston seal in clean brake fluid and slide it into position and then apply brake fluid to the new dust boot and put it over the piston. Instead of merely putting the piston into the bore, make sure you press it in evenly to prevent binding, then use Special Tool C-4689 or C-4842 plus Handle C-4171 to push the boot into place. Put the caliper back, push the piston all the way in and make sure the rotor is positioned if you removed it. Lower the caliper to the adapter, being careful about the guide pin bushings and fit and tighten the guide pin bolts to 35 Nm (26 ft. lbs.). While assembling the brake hose, add new special washers, put in the hose and tighten the banjo bolt to 47 Nm (35 ft. lbs.). Put the wheel and tire back on, tighten the wheel nuts to 135 Nm (100 ft. lbs.) in the order needed, lift the vehicle, remove the brake pedal depressor, bleed the hydraulic brake circuit and do a road test to check brake function.
