Current through Register Vol. 56, No. 14, July 15, 2024
(a) The number of
				defective brakes is equal to or greater than 20 percent of brakes on the
				vehicle or combination. Steering axle brakes are to be included in the 20
				percent criterion. A defective brake includes any brake that meets one of the
				following criteria:
1. Absence of effective
				braking action upon application of the service brakes, such as brake linings
				failing to move or contact breaking surface upon application. This is a
				category 2 violation. The penalty for this violation shall be $ 200.00 per
				wheel.
2. Missing or broken
				mechanical components including: shoes, linings, pads, springs, anchor pins,
				spiders, cam rollers, pushrods, and air chamber mounting bolts. This is a
				category 2 violation. The penalty for this violation shall be $ 200.00 per
				wheel.
3. Loose brake components
				including: air chambers, spiders, and cam shaft support brackets. This is a
				category 2 violation. The penalty for this violation shall be $ 200.00 per
				wheel.
4. Audible air leak at brake
				chamber. (Example: ruptured diaphragm, loose chamber clamp.) This is a category
				2 violation. The penalty for this violation shall be $ 100.00 per
				wheel.
5. Brake adjustment limits.
				Bring reservoir pressure between 90 and 100 psi, turn engine off and then fully
				apply the brakes.
i. One brake at 1/4 inch or
				more above the adjustment limit. (Example: Type 30 clamp type brake chamber
				pushrod measured at 2 1/4 inches would be one defective brake.) This is a
				category 2 violation. The penalty for this violation shall be $ 100.00 per
				brake.
ii. Two brakes less than 1/4
				inch beyond the adjustment limit also equal one defective brake. (Example: Type
				30 clamp type brake chamber pushrods measure--two at 2 1/8 inches.) This
				example would equal one defective brake. This is a category 2 violation. The
				penalty for this violation shall be $ 100.00 per brake.
iii. Any wedge brake where the combined brake
				lining movement of both top and bottom shoe exceeds 1/8 inch. This is a
				category 2 violation. The penalty for this violation shall be $ 100.00 per
				brake.
6. Brake linings
				or pads, except on power unit steering axles.
i. Cracked, loose, or missing lining. Any
				violation under (a)6i(1), (2), (3) or (4) below is a category 2 violation. The
				penalty for each violation shall be $ 300.00 per wheel. Missing lining, under
				(a)6i(5) below, is a category 1 violation. The penalty for this violation shall
				be $ 2,000 per wheel.
(1) Lining cracks or
				voids of 1/16 inch in width observable on the edge of the lining.
(2) Portions of a lining segment missing such
				that a fastening device (trivet or bolt) is exposed when viewing the lining
				from the edge.
(3) Cracks that
				exceed 1 1/2 inches in length.
(4)
				Loose fitting segments. (Approximately 1/16 inch or more movement.)
(5) Complete lining segment
				missing.
ii. The
				following chart shall be adhered to in determining brake adjustment limits, and
				is incorporated herein by reference.

WEDGE BRAKE DATA
The combined movement of both brake shoe lining scribe
						  marks shall not
exceed 1/8 inch (3.18 mm).
iii. Evidence of oil seepage into or out of
				the brake lining/drum interface area. This must include wet contamination of
				the lining edge accompanied by evidence that further contamination will
				occur--such as oil running from the drum or a bearing seal. Grease on the
				lining edge, back of shoe, or drum edge and oil stains with no evidence of
				fresh oil leakage are not conditions for out-of-service. This is a category 2
				violation. The penalty for this violation shall be $ 300.00 per
				wheel.
iv. Air brakes: Lining with
				a thickness less than 1/4 inch or to wear indicator, if lining is so marked,
				measured at the shoe center for drum brakes or less than 1/8 inch for disc
				brakes. This is a category 1 violation. The penalty for this violation shall be
				$ 500.00 per wheel.
v. Hydraulic
				and electric brakes: Lining with a thickness 1/16 inch or less at the shoe
				center for disc or drum brakes. This is a category 1 violation. The penalty for
				this violation shall be $ 500.00 per wheel.
7. Missing brake on any axle required to have
				brakes. This is a category 1 violation. The penalty for this violation shall be
				$ 5,000 per wheel.
