Ill. Admin. Code tit. 92, § A - Battery or Batteries through Exhaust System

Current through Register Vol. 46, No. 15, April 8, 2022

a) BATTERY OR BATTERIES

PROCEDURES/SPECIFICATIONS:

A minimum of one battery must be installed. Two or more suitably connected batteries may also be installed.

Battery or batteries must be securely mounted and free of excessive corrosion.

REJECT VEHICLE IF:

Battery or batteries are not securely mounted or are excessively corroded.

b) BATTERY CABLES

PROCEDURES/SPECIFICATIONS:

Check condition.

REJECT VEHICLE IF:

Cables are corroded or are not securely attached.

c) BRAKES

1) SERVICE BRAKES (AIR)

PROCEDURES/SPECIFICATIONS:

Must be equipped with service brakes on all wheels. (See IVC Section 12-301(a)(5).)

Service brakes must provide braking action on any axle required to have brakes. Application of service brakes could cause the vehicle to reduce speed without creating steering problems. All brake components must be in good condition. Brake linings or pads must be clean, securely attached and of sufficient thickness. There must be no mismatch of air chamber sizes and slack adjuster lengths across the steering axle of any power unit.

Exception: If the vehicle was manufactured before July 25, 1980 and has 3 or more axles, brakes are not required on the front wheels. However, if two of those axles are steerable, one of them shall have brakes on all wheels.

AGENCY NOTE: Prior to inspecting any components located under the vehicle, be sure wheels have been chocked.

Observe braking action while service brakes are applied. Inspect for the absence of braking action on any axle required to have brakes. An example of absent braking action includes missing brakes or brake shoes that fail to move upon application of a wedge, S-cam, cam or disc brake.

When the following brake components are visible, inspect for good working condition and secure attachment:

Shoes

Lining

Pads

Springs

Anchor Pins

Spiders

Cam Shaft Support Brackets

Cam Rollers

Push Rods (Air Only)

Air Chamber (includes Mounting Bolts) (Air Only)

Inspect air brake chamber for any audible air leaks (examples include ruptured diaphragm, loose chamber clamp, etc.).

REJECT VEHICLE IF:

Absence of braking action on any axle required to have brakes.

Visible brake components are broken or not secure.

Audible air leak at brake chamber.

BRAKE PERFORMANCE TEST

PROCEDURES/SPECIFICATIONS:

If Using Drive-On Pad Type Brake Tester:

Check vehicle's stopping ability before testing.

Drive vehicle onto brake machine pads at 4 through 8 m.p.h.

Apply service brakes to bring vehicle to a halt. Do not lock wheels.

Note the braking forces registered by the brake machine.

If Using Roll-On Type Tester:

Each axle must be tested separately. Transmission must be in neutral when testing brakes on any drive axle. Check vehicle's stopping ability before testing.

Drive front axle onto rollers and start roller motor.

Apply service brakes but do not lock the wheels.

Note the braking forces registered by the brake machine.

Repeat the above steps for each axle.

The total braking force on a vehicle must be determined by adding the results of the test on each axle.

REJECT VEHICLE IF:

Drive-On Tester:

Machine does not register a total braking force of at least 60% of the vehicle empty weight. Braking forces at opposite wheels on same axle vary more than 20%.

Computerized tester does not register a total braking force of at least 45% of the vehicle empty weight.

Roll-On Tester:

Machine does not register a total braking force of at least 60% of the vehicle empty weight. Braking forces at opposite wheels on same axle vary more than 20%.

2) BRAKE LININGS AND PADS

Inspect brake linings and pads for firm attachment to the brake shoe.

Inspect linings and pads for oil, grease or brake fluid saturation.

Measure brake linings for minimum thickness:

Air drum brakes - thickness must measure at least 1/4 inch at the shoe center.

Air disc brakes - thickness must measure at least 1/8 inch.

Hydraulic brake linings or pad thickness must measure more than 1/16 inch.

REJECT VEHICLE IF:

Any brake lining or pad is not securely attached to the shoe.

Any brake lining or pad is saturated with oil, grease and/or brake fluid.

3) AIR CHAMBER SIZE AND SLACK ADJUSTOR LENGTH

PROCEDURES/SPECIFICATIONS:

Inspect the steering axle to determine if air chamber sizes and slack adjuster lengths are the same.

REJECT VEHICLE IF:

Air chamber sizes and slack adjuster lengths are not the same on the steering axle.

4) PARKING BRAKE SYSTEM

PROCEDURES/SPECIFICATIONS:

Upon actuation of the parking brake control, including driveline hand controlled parking brakes, the brakes must be activated on the vehicle.

Apply parking brake control and determine if brakes have been activated.

REJECT VEHICLE IF:

Brakes on the vehicle are not activated when parking brake controls are applied.

Actuating mechanism does not fully release when brake control is operated.

5) BRAKE DRUMS OR ROTORS

PROCEDURES/SPECIFICATIONS:

The brake drums and rotors shall be free of cracks that open when brakes are applied. The brake drums and rotors shall not have any portion missing or in danger of falling away.

Inspect brake drums and rotors for overall integrity to identify if any portions are missing or if there are any flexural cracks.

AGENCY NOTE: A flexural crack is a crack resulting from the drum or rotor being "flexed" at a turn or bend in the metal. Caution should be taken to insure that short hairline heat cracks are not confused with flexural cracks

REJECT VEHICLE IF:

Any drum or rotor has a portion missing or in danger of falling away.

Any flexural crack in the drum or rotor opens when the brakes are applied.

6) BRAKE HOSE

PROCEDURES/SPECIFICATIONS:

All brake hoses shall be properly connected and free from damage or leaks.

Inspect for any bulge or swelling when air pressure is applied.

Inspect for any audible leaks.

Inspect for two hoses improperly joined, such as a splice made by sliding hose ends over a piece of tubing and clamping hose to tube.

Inspect for cracked, broken or crimped hoses.

REJECT VEHICLE IF:

An audible leak is present in brake hoses.

A bulge or swell is present when air pressure is applied.

Hoses are cracked, broken or crimped.

7) BRAKE TUBING
