Gently pull against the brake by releasing the clutch, and it should hold the vehicle. Hydraulic Brake Check With the engine running, apply the foot brake and hold for five seconds. The pedal should not move lose pressure during those five seconds. If equipped with a hydraulic brake reserve system, with the key in the off position, depress the brake pedal and listen for the sound of the reserve system electric motor turning on. Check that the warning buzzer and light is off.
Check the proper operation of the foot brake by moving the vehicle forward slowly at about 5 mph and applying the brake firmly. Air Brake System Check For air brake equipped vehicles, the proper procedures for inspecting the air brake system are as follows: Test Air Leakage Rate Static check With a fully-charged air system, typically at psi, turn the engine off, chock the wheels, release push in the parking brake button and trailer air supply button for combination vehicles and time the air pressure drop.
After the initial drop, the rate of pressure loss should not be more than 2 psi per minute for single vehicles and no more than 3 psi per minute for combination vehicles Test Air Brake System for Leaks Release push in the parking brake and trailer air supply button for combination vehicles , and apply pressure to the foot brake. After the initial drop in pressure, the rate of pressure loss should be no more than 3 psi per minute for single vehicles and no more than 4 psi per minute for combination vehicles.
Rapidly depress and release the foot brake to reduce air tank pressure. The low air pressure warning signal must come on before the pressure drops below 60 psi. Check that the Spring Brakes Activate Automatically Continue to rapidly apply and release the service brake pedal further reducing air pressure. The trailer air supply button for combination vehicles and parking brake button should pop out when the pressure falls to usually between 20 to 40 psi.
This should activate the spring brakes. Check Rate of Air Pressure Buildup While the engine is operating at RPM, the pressure should rise from 85 to psi within 45 seconds in dual air systems. Test Foot Service Brakes With normal air pressure, release the parking brake and trailer air supply button for combination vehicles , move the vehicle forward slowly at about 5 mph and apply the brakes firmly using the brake pedal. Test for any pulling to any one side or delayed stopping action.
Steering Box and Hoses Check that the steering box is mounted securely and is not leaking. Check for damage to power steering hoses and power steering fluid leaks. Steering Linkage Check that connecting links, arms, and rods from the steering box to the wheels are not worn and cracked. Check that the joints and sockets are not loose or worn and that there are no missing nuts, bolts, or cotter keys. Suspension Springs, Air Check for shifted, cracked, broken, or even missing leaf springs.
Check for broken and distorted coil springs. If equipped, check the air ride suspension for damage and leaks. Mounts Look for cracked or broken spring hangers, missing or damaged bushings, and broken, loose, or missing bolts, U-bolts or other axle mounting parts.
Shock Absorbers Confirm that the shock absorbers are secure and that there are no leaks. Brakes Slack Adjusters Look for missing, loose or broken parts. The angle between the adjuster arm and push rod should be not less than 90 degrees when the brakes are applied and when the brakes are released a little over 90 degrees.
When pulled by hand, the brake rod should not move more than one inch with the brakes released. Brake Chambers Check that brake chambers are not dented, cracked, or leaking and that they are mounted securely. Brake Hoses and Lines Check for worn, cracked or leaking hoses, lines, and couplings. Drum Brake or Rotor Check for dents, cracks or holes, and loose or missing bolts.
Brake linings and pads should not be worn thin. Brake Linings Where visible, check that a reasonable amount of brake lining is showing. Wheels Rims Check for damaged or bent rims.
Rims cannot have welding repairs. Tire condition: Check that tread is evenly worn and without cuts or damage to tread or sidewalls.
Valve caps and stems should not be missing, broken, or damaged. Tire inflation: Check for proper inflation with a tire gauge or by striking tires with a mallet. Lug Nuts Check for any missing lug nuts, cracks, distortions, and for signs of looseness such as rust trails or shiny threads.
Check for cracked or distorted bolt holes. Spacers Spacers should not be bent, damaged, or rusted through. Spacers should be centered evenly. Side of Vehicle Doors and Mirrors Check doors for any damage and that they open and close properly. Hinges should be secure with seals intact. Mirrors and mirror brackets should be mounted securely. Battery and Battery Box Check to see that batteries are secure, for tight cable connections, and that cell caps are present.
Check for signs of excessive corrosion. More information on enforcement in Utah can be found on the Utah State Plan website.
UOSH offers voluntary and cooperative programs that focus on reducing worker injuries, illnesses, and fatalities. UOSH also offers on-site consultation services which help employers comply with occupational safety and health standards and identify and correct potential safety and health hazards.
These consultation services are offered without citations or penalties to private sector employers as well as state and local government entities. In the private sector priority is given to small businesses and businesses in high-hazard industries.
These services are confidential and offered only at the employer's request. For more information about these programs and other services available, please visit the Utah State Plan website.
Informal conferences are conducted in the UOSH office in an effort to resolve cases. More information on these processes can be found on the Utah State Plan website. OSHA makes every effort to ensure that this webpage is accurate and up-to-date; however, for the latest information please contact the State Plan directly. Lisa Stevens lstevens utah.
