135. The mechanical and hydraulic components of the brake system shall comply with the following standards:

(1)  all the parts shall be adequate, securely mounted and none shall be missing, seized or so damaged or worn out as to hamper the good working order of the brake system;

(2)  the lines and the fittings shall be adequate and shall not be crushed, pinched, cut or so cracked that the cord is exposed, nor bulged, broken, weld, excessively worn or corroded; furthermore, the fasteners shall be adequate, at the intended places and tight enough to prevent the lines from vibrating or rubbing against adjacent parts;

(3)  the hydraulic system shall show no visible evidence of leakage where the handbrake or pedal is fully depressed;

(4)  the master cylinder shall be securely mounted, show no signs of internal or external leaks, be fitted with a fluid-tight cover and the brake fluid level shall not be below the level specified by the manufacturer;

(5)  the brake lever and brake pedal shall be adjusted and located according to the manufacturer’s standards;

(6)  the warning light shall be adequate;

(7)  the brake pedal shall be of a non-slip type, securely fixed to its rotation axis, correctly aligned and move without excessive friction;

(8)  the anti-lock brake system shall be adequate and the warning light shall go off within the time specified by the manufacturer;

(9)  the internal brake components shall comply with the following standards:

(a)  the bonded brake linings shall be at least 1.6 mm thick, while riveted linings shall be at least 3.2 mm thick or 1 mm above the rivets, being measured at the thinnest point excluding the bevelled part;

(b)  the linings shall not be unbound from their support, broken, contaminated by oil or grease, cracked more deeply than half the remaining thickness or worn in an extremely uneven way; furthermore, the linings shall be securely attached to the support and no rivet shall be missing or loose;

(c)  the brake linings shall be adjusted according to the manufacturer’s standards, or so that the clearance between the linings and the drum be as small as possible without causing friction when the brake is released;

(d)  the wear indicator shall not be in contact with the drum or disc or exceed the manufacturer’s standards;

(e)  the pistons of a hydraulic brake shall move when the brake lever or pedal is lightly depressed; furthermore, there shall be no fluid leaks around them or along the lines and connections;

(f)  only superficial cracks caused by heat may be present and reach the outer edge of the friction surface of the drum or disc; there shall be no other crack or leak on the other parts of the drum or disc;

(g)  a brake disc shall not be thinner than the stamped dimension or the dimension specified by the manufacturer and shall not have a groove whose depth reduces the thickness below the prescribed thickness, or out of true by more than 0.13 mm;

(10)  the caliper shall not be seized, cracked, broken, poorly installed or leak;

(11)  there shall be rotation resistance on the wheel on which the brake is applied; where the brake is released, the wheel shall be totally free to turn and no part of the brake system shall be broken or be damaged consequently to such test;

(12)  the hydraulic brake control shall not depress completely where a moderate force is applied for a minute and the movement of the control shall not exceed 65% of the total possible movement; and

(13)  the parking brake of a 3-wheel motorcycle shall comply with the following standards:

(a)  the mechanism for the application of the parking brake shall be applied and released several times to make sure that the cables and mechanism work freely;

(b)  the parking brake shall prevent the motorcycle from moving when fully applied on a flat surface, with the gearshift lever placed in the drive position in the case of an automatic transmission or, in the case of a manual transmission, in the highest gear that will allow a normal forward start, while the motorcyclist smoothly attempts to move the vehicle forward; furthermore, the wheels shall be completely free to turn where the brake is released;

(c)  no mechanical component of the parking brake shall be missing, so worn as to affect the good working order or out of order, misaligned, not securely mounted, broken, cracked, seized up, slack, weakened, out of shape, disconnected or damaged.
