INSPECTION OF SECOND COAST BRAKE
COMPONENT
If the lining of the brake band is exfoliated or discolored,
or even part of the printed marks is defaced, replace the
brake band.
ASSEMBLY OF SECOND COAST BRAKE
PISTON
1. SELECT PISTON ROD
If the band is OK but piston stroke not within the standard
value, select the piston rod.
Piston stroke: 2.0 - 3.5 mm (0.079 - 0.138 in.)
There are two lengths of piston rod.
Piston rod length: 95.2 mm (3.748 in.)
96.3 mm (3.791 in.)
2. INSTALL PISTON ROD
(a) Install the plate washer and inner spring to the
piston rod.
(b) Install the E-ring while pushing the piston.
