NSPECTION
6.2.1 Pad Wear
The running clearance (air gap) between lining and disc must be maintained within the
specified limits. Failure to do so will result in sluggish brake response and excessive air
consumption. When the running clearance has reached 0
.04” [1 mm] the brake mus t be
adjusted back to 0 .01” [ 0.25 mm] per shoe. Refer to section 5.3.2.
For pressure applied brakes maintain the proper running clearance between the shoe and the
disc to ensure fast response and minimize the air consumption.
The maximum allowable pad life has been reached when the brake pad has worn down to
3/16” [4.8 mm] thick . The lining must be replaced before the shoe lining bolts or rivets start
making contact with the brake disc.
6.2.2 Pin Wear
The pivot pins must be removed for inspection once every five years. If there is any evidence
of heavy scoring more than 0
.01” [ 0.25 mm] deep or if any area of the pin has been worn
down by more than 0 .01” [ 0.25 mm] then replace the pins.
6.2.3 Brake Disc
The brake disc must be inspected periodically to monitor the condition of the braking surface.
When the condition of the braking surface has deteriorated to the point that the quality
requirements in
section 3.2 are no longer met the disc must be removed and resurfaced or
replaced. Follow the minimum thickness allowances in the table below as a guideline for
when a disc must be replaced.
