There is no reserve travel in the lever or pedal when the brake is fully applied. Parking or holding brake will not hold the vehicle stationary with engine running at a slightly accelerated speed with shift lever in drive position for automatic transmission or shift lever in low gear while engaging the clutch on a standard transmission.Ĭheck parking brake components for general condition.Ĭable(s) are visibly frayed or frozen, or there are missing or defective cotter pins or broken or missing retracting springs or worn rods or couplings. ![]() If vehicle is equipped with an "automatic parking brake release" type, that releases itself when gear selector is placed in a position other than park or neutral, omit paragraph 1 of this subdivision and inspect all other points of the parking brake. There is any disconnected, improperly installed, broken, frozen, seized, bypassed, or missing component of the braking system. Visually inspect components of the braking system. Inspect discs for any distortion or scoring that would impair braking system.ĭistortion or scoring impairs the braking system. There is evidence of mechanical damage other than wear. There are substantial cracks extending to edge. Inspect for substantial cracks extending to edge of rotor. Inspect for contaminated friction surface.įriction surface is contaminated with oil, grease, or brake fluid. Inspect for cracks on the outside of drum. There are substantial cracks on the friction surface extending to open edge. Inspect the condition of the drum friction surface for substantial cracks extending to the open edge of the drum (short hairline heat check cracks should not be considered). If friction surface is contaminated with oil or grease or there is metal-to-metal contact. Also inspect for contamination.įriction material is broken, cracked or not firmly and completely attached to its mounting. Inspect for audible or visual sign from disc brake wear sensors, if vehicle is so equipped.Īll linings and pads Inspect for broken or cracked linings and parts of linings not firmly attached to their mounting. Lining is worn to less than 1/ 32 inch over any rivet head.Ĭheck Condition of Brake Linings and Pads Measure lining thickness above rivet head at thinnest point. ![]() Riveted linings Inspect for loose or missing rivets. Depress brake pedal and while maintaining force, start engine.īrake pedal does not fall slightly under force when engine starts.īonded linings Measure the lining thickness at the thinnest point. With engine stopped apply brakes several times to deplete power assist in system. On vehicles equipped with power brakes the engine should be running.īrake pedal does not hold its position for at least 60 seconds without fading. ![]() Pedal reserve is less than ⅓ of the possible travel or less than the manufacturer's specification.Īpply brakes, using normal foot pressure. While the vehicle is stopped, depress brake pedal under normal foot pressure (if vehicle is equipped with power brakes, engine should be running for this test). The emissions inspection requirements may be found in sections 79.24, 79.25, and 79.26 of this Part. Additional safety inspection requirements for all motor vehicles and trailers, except semi-trailers, that have a MGW, as indicated on the vehicle registration certificate, over 10,000 pounds and under 18,001 pounds, except when the registrant requests a heavy vehicle inspection, may be found in section 79.23 of this Part. Additional safety inspection requirements for all trailers, except semi-trailers, that have a MGW, as indicated on the vehicle registration certificate, under 10,001 pounds, may be found in section 79.22 of this Part. This section comprises the safety inspection or the safety portion of a safety and emissions inspection for all motor vehicles that have a seating capacity, as indicated on the vehicle registration certificate, under 15 passengers, all motor vehicles and trailers that have a MGW, as indicated on the vehicle registration certificate, under 18,001 pounds, except: motorcycles those motor vehicles and trailers that have a MGW, as indicated on the vehicle registration certificate, over 10,000 pounds and under 18,001 pounds, when the registrant requests a heavy vehicle inspection and semi-trailers.
