13. Apply two level teaspoons of Aeroshell Grade 5
(ES–1246) grease on each side of the assembly.
Apply it evenly along the full length of the
V-groove and anchor plate rail, and apply one
level teaspoon evenly on both sides of the key
and spring. Any accumulation of grease after
caliper installation is done should be packed at
each end of the rail and along the top of the rail
or key at the V-groove.
14. Being careful not to get grease or dirt on the pad
face, reinstall each brake pad.
15. Grasping the caliper firmly, rest the V-ways on
the forward anchor plate torque rail (the large
rail) and swing the caliper into place. Make sure
that the brake hose is not twisted. Do not get
grease on the pad faces or rotor surfaces.
16. With the caliper installed and firmly seated on
the forward rail (large rail), insert the key and
spring between the caliper V-way and the anchor
rail from the inboard end of the anchor rail.
17. Carefully drive the key and spring into place. In-
stall the key retainer screw and tighten 12 to 18
lbf·ft (16 to 24 N·m).
18. Install the wheels. For instructions, see Group
