  2.  
  3. Use a pin punch to depress the cylinder retaining pin and slide the cylinder out of the bracket.

Fig. Fig. 4 Disassembled Alliance, Encore, R-18 and Fuego caliper-note the piston seal (5) and slider seals (6)

  1. Remove the dust cover from the piston.
  2.  
  3. Place a thick rag or a thin block of wood in the caliper where the pads normally go.
  4.  
  5. Apply compressed air with the air chuck in the brake hose hole. Keep your fingers away from in front of the piston, as it can pop out with considerable force.
  6.  
  7. Remove the caliper seal from its groove in the bore.
  8.  
  9. Clean all parts in methyl alcohol. If the bore is pitted or scored, it can be honed by a machine shop. If damage is excessive, replace it.
  10.  
  11. Assemble all parts in reverse order of disassembly. Coat the piston and seal with clean brake fluid prior to assembly. Tighten the caliper mounting bolts to 50 ft. lbs. on the R-12, R-15, R-17 and Gordini; 44 ft. lbs. on the R-18 and Fuego and 26 ft. lbs. on the Alliance.
