Rinse cylinder in clean brake fluid. Shake excess rinsing
fluid from cylinder. Do not use a cloth to dry cylinder, as lint
from cloth cannot be kept from cylinder bore surfaces.
ASSEMBLY
1) Install secondary piston assembly into cylinder.
2) Install primary piston in cylinder.
3) Depress, and install circlip (2).
4) Install piston stopper bolt with pistons pushed in all the way
and tighten it to specified torque (For vehicle without ABS).

(a) : 10 N·m (1.0 kg-m, 7.5 lb-ft)
Fill Reservoir
NOTE:
See NOTE at the beginning of this section.
Before assembling, wash each part in fluid recom-
mended to use for that vehicle.
1. Rod
CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use container which has
been used for mineral oil or which is wet from water. Min-
eral oil will cause swelling and distortion of rubber parts
in hydraulic brake system and water will mix with brake
fluid, lowering fluid boiling point. Keep all fluid contain-
ers capped to prevent contamination.
