REMOVAL & INSTALLATION



Challenger
  1. Block the front wheels, jack up the rear of the car and support on jackstands. Remove the rear wheel and the caliper dust cover.
  2.  
  3. Disconnect the parking brake cable.
  4.  
  5. Remove the spring pin and stopper plug.
  6.  
  7. Move the caliper back and forth to loosen, then remove the caliper from the support.
  8.  

The brake hose need not be disconnected; however, do not suspend the weight of the caliper from the hose.

  1. Take time to examine the location of the various clips and springs. Remove the pads from the support. Do not mix up the inner and outer clips, they must be installed in the same location.
  2.  
  3. Seat the caliper piston by pushing in while turning clockwise (use a special tool). When fully seated, one of the grooves on the piston must be located vertically at 12 o'clock to accommodate a projection of the brake pad. Install new pads into the support and install the caliper.

  1. Raise and support the rear end on jackstands.
  2.  
  3. Remove the wheels.
  4.  
  5. Disconnect the parking brake cable.
  6.  
  7. Remove the lower caliper lockpin, and (depending on year), the upper guide pin.
  8.  

There is a grease coating on the bolt. Make sure that it is not removed or contaminated.

  1. Rotate the caliper upward (if upper guide pin removal is not required) and suspend it with string from a nearby suspension member.
  2.  
  3. Remove the brake pads and shims.
  4.  
  5. Remove the clips from the pads.
  6.  
  7. Clean all parts in solvent made for brake parts.
  8.  
  9. Inspect the dust boot on the caliper piston. If it is torn or brittle, replace it, and consider rebuilding the caliper.
  10.  
  11. Inspect the shims and liners and replace them if damaged.
  12.  
  13. Remove the cap from the master cylinder reservoir and siphon off about 1 / 4 in. of fluid.
  14.  
  15. Using tool MB990652, align the grooves in the caliper and piston and force the piston back into the caliper as far as it will go. Remove the clamp.
  16.  
  17. Install the pads and shims after attaching the clips in reverse order of removal.
  18.  

Never replace just one set of pads, pads should be replaced on both front wheels at the same time.

  1. Rotate the caliper back into position and install the lower slider pin. Torque the pin to 45 ft. lbs.
  2.  
  3. Start the engine and depress the brake pedal. Hold it depressed for about 5 seconds. Turn the engine OFF.
  4.  
  5. Rotate the brake rotor a few times. Using a spring scale hooked to one of the lugs, measure the brake drag. Remove the pads and perform the spring scale test again. The difference between the drag test with and without the pads should not exceed 15 lbs. If the difference does exceed 15 lbs., the caliper will have to be rebuilt or replaced.
