To confirm that boot is fitted in its groove in cylinder properly, pull piston out of cylinder a little but do not take it all out.
NOTE: Boot's face (1) should be at the same level from cylinder's face (2) all around.

Caliper

Before installing caliper (cylinder body) to carrier, check to ensure that guide pin (pin bolt) inserted in each caliper carrier hole can be moved smoothly in thrust direction.

NOTE: Where temperature gets as low as -30°C in cold weather, use rubber grease whose viscosity varies very little even at -40°C (-40°F).
