All railcars cars in the shop for which there is a reason to believe the brakes may be
defective, i.e., built-up tread, flat spots, signs of overheating, failure of set and release
test, etc., should have a single car air brake test.
Before a railcar is released from a shop or repair track, it shall be determined that the
brake pipe is securely clamped, angle cocks in proper position with suitable clearance,
valves, reservoirs and cylinders tight on supports, and supports securely attached to
Old stencil dates for COT&S shall not be changed until the work is completed.
All rubber parts shall be replaced during COT&S on all types of brake valves.
Air hose gaskets shall be renewed during COT&S.
Periodic inspection of the brake system shall include air brake hoses. Any hose over
eight years old or date obliterated shall be renewed. Age is determined by the date
molded on the hose.

longitudinal or spiral cracks that expose the fabric, or heat damaged hoses or
permanently twisted, kinked, crushed or flattened or damaged wire reinforced hoses
shall be replaced.
Brake beam hangers worn to 3/4 inches or less, measured vertically or through the
comers of the radius shall be repaired or replaced. See Figure A-1 for examples of
brake beam hangers.
Brake beam hanger brackets broken, bent, or worn oblong to a depth of 1/2 its
original diameter, or worn oblong so that remaining material is less than 60% of the
original section shall be repaired or replaced.
Brake connection pins, hanger pins, or bolts shall be replaced if an original 1 inch
diameter is less than 7/8 inch. If the original diameter of pins or bolts was greater than
1 inch and has worn to less than 1 inch, the pins or bolts shall be replaced.

worn 20% or more of the original section shall be replaced.
