Q: How to Maintain a Rear Disc Brake Caliper on 2004 Dodge Neon?
A: Start by pressing down the brake a bit using the brake pedal holding tool. Let the vehicle down, take off the rear wheel and tire and then raise the vehicle again. After removing the banjo bolt, discard the older washers inside the hose and insert some new ones in place. In case it becomes difficult to remove the piece, pull back the caliper piston a little to add space. Get rid of the guide pin bolts and pull the caliper assembly off the brake adapter rotating the top away from the rotor and lifting it up. Look at and clean the caliper before you start disassembling it. Pull the bushing sleeve back in the brake caliper and once it's out, pull the rubber guide pin bushing from one side of the brake pad. When you need to take apart the piston and seals, hang the caliper off the rotor, add another piece of wood in between the caliper and piston and gently push the piston out by depressing the brake pedal. Come apart the brake fluid flex hose and remove it. Place the caliper in a vise protected by jaws, take off the piston dust boot and gently use a soft tool to get the piston seal out of its groove. Check the piston bore for damage, then clean it and hone it using Caliper Hone, Special Tool C-4095 and should not increase the bore size past 0.0254 mm (0.001 inch). Survey the caliper piston to see if damage exists and remove it if anything is wrong. Moisten some cotton cloth with enough water to spray on your brake system parts, but try not to use compressed air. Check for any damage in the dust boots and if there are leaks or damage, open the caliper up, clean and replace all defected seals and dust boots. To assemble, bend the guide pin bushing and put it into the mounting boss so it is snugly set. Apply grease along the inside walls of the bushing, then put the guide pin sleeve into place. Wet a recently purchased piston seal with clean brake fluid and place it inside the caliper bore. Next, using brake fluid, cover the boot and set it over the freshly installed piston. Insert the piston into the caliper bore and keep all the pressure even so it doesn't become stuck. Fit Special Tool C-4689 and Handle into the counterbore, drive the boot in, then put in the brake shoes. While installing the caliper, pull the piston all the way back, lube the adapter's caliper slide abutments and mount the caliper over the brake rotor, making sure not to twist the guide pin bolts. Make sure to set the guide pin bolts at 22 Nm (192 inch lbs.) and the banjo bolt at 24 Nm (210 inch lbs.) with fresh washers. Install the new tire and wheel assembly, tighten the wheel nuts to 135 Nm (100 ft.lbs.), raise the automobile, remove the caliper bleeder tool, perform air bleeds on the brakes and drive the vehicle to confirm correct braking.
