Brake Caliper: Testing and Inspection

INSPECT BRAKE CALIPER INNER PARTS
Cylinder Slide Guide pin





Check guide pin for smooth movement as shown. If it is found faulty, correct or replace. Apply rubber grease to guide pin outer surface. Rubber grease should be the one whose viscosity is less affected by such low temperature as -40°C (-40°F).

Bush Dust Boot and Cylinder Boot





Check boots for breakage, crack and damage. If defective, replace.

Piston Seal





Excessive or uneven wear of pad lining may indicate unsmooth return of the piston. In such a case, replace rubber seal.
