Fig. 5E-13 Clinching Outboard Shoe
bottom edge of the outboard lining to rest on the
outer edge of the rotor and make sure that there is no
clearance between the tab at the bottom of the out-
board shoe and the caliper abutment. Clamp the out-
board shoe to the caliper with moderate pressure
using a 1/4" thick metal bar to bridge the caliper
cut-out (Fig. 5E-13). Use a clean C clamp to avoid
contamination of the brake lining and do not use
excessive force which may deform the lining face.
Fig. 5E-14 Installing Mounting Bolts
Using gripping pliers, clinch both upper ears of the out-
board shoe. Locate the pliers 1/8 to 1/4 inch from the
outer edge of the shoe ear (Fig. 5E-13). After clinching,
the tangential and radial clearance between the caliper
and the shoe ears should not exceed 0.005 inch in either
direction. Re-adjust the pliers and repeat the clinching
procedure if necessary.
NOTE: Brake rattle or click on application may
occur
if
shoes are not properly clinched.
6. After clinching, remove the C clamp and position the
caliper over the rotor, lining up the holes in the
caliper ears with the holes in the mounting bracket.
NOTE: Make sure that the brake hose is not
twisted or kinked and that the skirt of the metal
fitting which attaches to the caliper is installed
BETWEEN the ears on the caliper boss as
shown in Fig. 5-19.
7. Start the bolts through the sleeves in the inboard
caliper ears and the mounting bracket, making sure
that the ends of the bolts pass under the retaining ears
on the inboard shoe (Fig. 5E-14).
CAUTION: See caution on Page I of this section
regarding fistenem referred to in Steps 8 and 9
below.
8. Push the bolts through to engage the holes in the
outboard caliper ears, at the same time threading the
bolts into the mounting bracket or steering knuckle.
