Q: How to Service and Repair a Rear Brake Caliper on 2005 Chrysler Crossfire?
A: Before handling the rear brake caliper, support the vehicle on jacks, then take out the rear tire and wheel assembly. Take out some of the fluid using a clean syringe that sucks liquid from the master cylinder brake reservoir. Take out the bolts holding the caliper mount and carefully unfasten the caliper from the knuckle so you don't drip brake fluid onto painted areas. Rotate the caliper and hold the brake hose with a wrench to pull the brake hose out. Punch out the retaining pin and once it's out, remove the anti-rattle clip before taking out the brake pads from the caliper. Take apart the caliper to check it out for wear or damage; afterward, clean its inside parts with clean brake fluid or Brake Clean, not with gasoline, kerosene or other solvents. Check the caliper piston, since you should use a new one that matches the original in material, as steel and phenolic resin pistons are not the same. To clean the deposit from the piston, use a soft brass wire brush or roughened towel, but do not use anything that could cover or remove the chrome layer. If either the piston is stuck or the cylinder's bores are worn or rusted, you should replace the component whole of either the fixed or floating brake caliper. If rust is light, simply clean it with a polishing cloth; if it's heavier close to the piston seal groove, it should be removed with fine-grain emery paper. To install, first put on the rear brake pads, link the brake hose to the caliper and ensure the hose isn't twisted or folded before securing the caliper to the knuckle with the bolts tightened to 55 Nm (41 ft. lbs.). Whether you pressure-bleed or do it yourself, fill the brake system and then hook back up the wheel and tire assembly. Until you can push the brake pedal down with force, do not move, then set the car on firm ground, lower it, pump the brake pedal to make the caliper pistons and brake pads fit in place, top off the brake fluid reservoir if it's needed and finally, check for possible leaks.
