Current through Register Vol. 56, No. 24, December 18, 2024
Section 16:53A-3.2 - Brake system(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.
