Figure 8 Installing Spring Pins
• Piston assembly (14) must be bottomed into
caliper housing (27) bore before installing new
shoe and linings (2 and 3).
1. Lubricated new two-way check valve (15) into end of
piston assembly (14).
2. Inboard shoe and lining (3) with wear sensor (4) at
leading edge of shoe during forward wheel rotation.
• Make sure shoe pins (33), on back of inboard
shoe, engage holes (34) in end of piston assem-
bly (14).
• Use J 36621 to align piston holes if necessary.
3. Outboard shoe and lining (2).
NOTICE: See "Notice" on page 5 - 1 .
NOTICE: In the following steps, do not use a steel
drift to install pins. This will damage ends of pins and
make later removal of pins difficult.
4. One spring pin (1) aligning holes in shoe and linings (2
and 3).
• Tap in pin (1) using hammer and soft brass rod
or drift until end of pin just emerges from
inboard face of caliper housing (27).
5. Springs (5) and remaining pin (1).
• Position pins (1) so that slots in pins face each
other. This will ease assembly of springs (5).
