i originally filed a complaint against the pad manufacturer but it seems to be the composite piston in the caliper that is intermittently causing the brakes to overheat. the pedal travel goes to zero and the brake is locked. this is a manufactures defect and a hazard. it would be easy for these brakes to fail in highway conditions and have the grease melt out of the bearings from the heat and brake fluid to boil. this car has been garaged its entire life and maintained. it is chrysler that in the interest of profit created a safety hazard. *tr
