Comment: Motorcycles M-IV-1 3 [Definition 3] This definition implies that a dual braking system is required on all motorcycles. Territory of Guam Ordinance allows motorcycles to be equipped with a rear wheel brake only. Response: The Brake Service System definition will be changed to indicate that a .braking capability is required on all wheels that were originally so equipped. Brakes on both front and rear motorcycle wheels have been standard for many years. Such brakes have been required on all motorcycles manufactured on and after September 1, 1973 by Federal regulation. It is not believed that the intent of the Territory of Guam Ordinance is to permit a reduction in the safety capability of motorcycles but rather states a requirement relating to an obsolete industry practice.*

TITLE 150: DEPARTMENT OF PUBLIC SAFETY (6) Parking Brake Notes for Inspectors

1. Parking brakes on most vehicles function through at least one set of the rear service brake shoes.
2. A few vehicles have disc type service brakes on all four wheels which makes it necessary to have separate drums for the parking brakes. These drums and linings should be inspected in a manner similar to those for service brakes.

1. Brake performance should be inspected only after all other inspections of the braking systems have been completed. The brake performance test should not be made if system components are defective.
2. Using the service brake only, the stopping ability of the vehicle should be tested by one of the three methods described below.
3. The service brake road test, Method (a), should be conducted on a level, dry, hard, smooth surface road or area that is free from loose material, oil or grease. Caution: Always check for braking action at a very slow speed before operating the vehicle.
4. If Method (c) is used, the roller-type brake dynamometer should have rollers which are dry, smooth, and free from oil or grease. The machine indicates both braking effort and imbalance. Brakes on front and rear axles are evaluated separately’ Method (a) - Road Test Tools and Equipment

TITLE 150: DEPARTMENT OF PUBLIC SAFETY testers that measure braking force in the testing of vehicles other than passenger vehicles or light trucks is very questionable. The dimensions of these brake testers do not permit practical and reliable testing on combination vehicles. Use should therefore be restricted to two-axle vehicles. The simulated road surface of these machines will occasionally exhibit much higher coefficients of friction than is possible on the highway. Excessive braking should therefore be avoided, because braking distribution information is distorted. For drive-on-and-stop test machines the vehicle is driven on the pads at speeds of 4 to 8 mph. When the brakes are applied at the time the vehicle is moving on the pads, the braking effort at each wheel causes a proportionate movement of the pad against the measuring system. The braking force on the pads is measured by indicating or recording instruments. The roller-type brake testing machine has powered rollers that turn the individual wheels while the brakes are applied in order to measure the brake force developed.

TITLE 150: DEPARTMENT OF PUBLIC SAFETY Tools and equipment, if required, will be listed above each separate inspection procedure. Definitions

1. Sideslip (or Scuff) The amount of sidewise front tire slippage occurring on the road surface while vehicle is traveling straight ahead.
2. Wheel Plane The central plane of the tire-wheel system, perpendicular to the axis of rotation.
3. Camber The inclination of the wheel plane to the vertical. It is measured in degrees and considered positive when the wheel leans outward from vertical at the top and negative when the wheel leans inward.
4. Caster The angle viewed from the side between the sterring* axis (axis of kingpin or ball joints) and the vertical. It is measured in degress* and is considered positive when the steering axis at the top is included rearward and negative when the steering axis is inclined forward.

• So in original.

5. Toe (In or Out) As measured in inches, it is the difference in the traverse distances between the wheel planes taken, respectively, at the extreme rear and front points of the tire. When the distance at the rear is greater than at the front, the wheels are said to be “toed-out.”
6. Steering Axis (King Pin) Inclination The angle between the steering axis and the center line of the wheel spindle.
7. Toe-Out on Turns The angle of relationship between the inner and outer front wheels during turns.
8. Play Any free movement of the front wheels and suspension components.
9. Lash The condition in which the steering wheel may be turned through some part of a revolution without associated movement of the front wheels.
10. Travel The complete, full turn of the steering wheel and linkage, free from binding or interference, in both directions from straight ahead to designed stops.
11. Loaded The condition where the front wheels of the vehicle are on the ground, bearing their full portion of the weight of the vehicle.
12. Shock Absorbers Energy-dissipating devices which provide damping of sprung and unspring mass relative motions; increase vehicle stability; and improve steering, handling, and ride performance. © 2016 by The Commonwealth Law Revision Commission (August 30, 2016) Page 71 of 147

3. A squealing noise, particularly during acceleration or parking, may be an indication of a slipping or loose drive belt.
4. Belt tension can be visually inspected by using a strand-type belt tention gauge or by hand pressure.
5. Vehicle manufacturer’s specifications should be consulted, but generally if a belt can be depressed by more than 1/2 inch of thumb pressure midway between the drive and driven pulleys, the drive belt is too loose.
6. The correct power steering fluid level can usually be checked against markings on the dipstick or filler neck.

TITLE 150: DEPARTMENT OF PUBLIC SAFETY Notes for Inspectors

1. Many 1967 and all later model cars have been equipped with an Energy Absorbing Steering Column. This special column was designed to absorb energy by controlling the collapsing of its components. It collapses under impact from either end of the column steering gear end and/or steering wheel end. To determine if the components are capable of functioning as designed, a careful inspection should be performed.
2. There are many variations of the energy absorbing column. It is recommended that the manufacturer’s specifications be consulted if there are any detailed questions. The system may include one or more of the four devices shown in Figure 2, and the simplest to inspect is the shear capsule. Procedure Reject Vehicle If: A. Absorbing Steering Column A.

TITLE 150: DEPARTMENT OF PUBLIC SAFETY (7) Ball Joint Wear Notes for Inspectors

1. Inspection of ball joints on models prior to 1973 must be conducted with the joints unloaded. Beginning with some 1973 models, however, some manufacturers provide a wear indicating ball joint to facilitate inspection, in which case a visual inspection is made with the joints loaded.
2. For inspection on models without wear-indicating ball-joints, ball joints must be unloaded.
3. On models with wear-indicating ball joints, inspection is in accordance with the manufacturer’s specifications.
4. Non-load carrying ball joints should not show an appreciable amount of wear. If there is any perceptible looseness, rejection and replacement by a qualified mechanic should be considered.
5. In checking for vertical motion of ball joints, keep in mind that the load carrying joint is unloaded, and that a pry bar pressure sufficient only to lift the weight of the wheel assembly is required. If the inspector uses the “leverage” of a pry bar to exert excessive pressure, he can easily “force” an apparent ball joint movement and get a false reading. This may result in expensive replacement of perfectly good joints.
6. Refer to Appendix A following this section, for additional front suspension information. Tools and Equipment
7. Floor jack and stand to lift vehicles without wear indicating ball joints.
8. Dial indicator to measure horizontal movement between ball joint and the socket.

Appendix A Additional Front Suspension Information In virtually all vehicles used on roads, streets and highways steering is accomplished by turning the front wheels in the direction of intended travel. In these vehicles a flexible suspension unit is used on each wheel to provide for movement between the wheel and the chassis. In order to provide for these movements of the front wheels various steering-suspension arrangements are in general use. © 2016 by The Commonwealth Law Revision Commission (August 30, 2016) Page 82 of 147

TITLE 150: DEPARTMENT OF PUBLIC SAFETY

1. Solid Front Axle. A one piece axle is supported by one or two flexible suspension units (springs). The front wheels are attached to each end and steering is accomplished by using a pin (kingpin) and bushing arrangement.
2. Twin “I” Beam. An adaptation of the solid front axle where each front axle is attached to one end of an individual solid axle. The other end of each axle is attached to the chassis with a pin and bushing. Steering is accomplished by using a pin (kingpin) and bushing arrangement. This system provides independent suspension for each front wheel. Usually a flexible suspension unit (spring or torsion bar) is provided for each wheel.
3. Double Control Arm Systems These systems provide for vertical movement of the front wheels by the use of upper and lower control arms and individual suspension units for each wheel. Three variations are used to provide steering control. a. Two Ball Joint System. This is the most common system used on U.S. manufactured vehicles. An upper and lower ball joint is used on the upper and lower arms, respectively, to hold the front wheel in the proper position and permit the necessary movement. The flexible suspension unit can be attached to either control arm. b. Pin and Bushing System. In this system pins and bushings are used on the upper and lower control arms to hold the wheel in the proper position and permit the necessary movement. The flexible suspension unit can be attached to either control arm. c. Combination System. In this system a ball joint is attached to the lower control arm and a pin and bushing arrangement is attached to the upper control arm to hold the front wheel in the proper position and permit the necessary movement. The flexible suspension unit is usually attached to the upper control arm. This system has been commonly used on American Motors vehicles. d. Single Control Arm System. This system has only a lower control arm. The wheel is attached to this control arm by means of a ball joint. A strut combining the suspension unit and shock absorber is used in place of an upper control arm. Attachment to the chassis is accomplished by using a flexible (rubber) bushing. The flexible suspension unit is always mounted on the strut. Definitions
4. Loaded Ball Joint The load carrying ball joint when the weight of the vehicle is on the ball joint.
5. Unloaded Ball Joint The load carrying ball joint when the weight of the vehicle is removed from the ball joint.
6. Load Carrying Ball Joint The ball joint which supports the weight of the vehicle. This is always the ball joint which is on the control arm to which the spring or torsion bar is attached.
7. Non-Load Carrying Ball Joint A ball joint which does not support the weight of the © 2016 by The Commonwealth Law Revision Commission (August 30, 2016) Page 83 of 147

TITLE 150: DEPARTMENT OF PUBLIC SAFETY vehicle. This is always the ball joint which is on the control arm that does not have a spring or torsion bar attached. The only function of this ball joint is to hold the wheel in the proper position. This Ball joint has, in some cases, been incorrectly termed the unloaded ball joint. 5. Pre-Loaded Ball Joint A ball joint containing a spring or similar device within the socket to hold the ball tightly against the socket. Non-load carrying ball joints are usually pre-loaded. These ball joints will usually show no movement under test conditions.

Casting is cracked or there is evidence of wear in the clamping area. Brakes General Instructions Two items of special interest must be considered by the inspector when evaluating the braking on large, heavily loaded vehicles. a. Safety – The vehicle or combination of vehicles may weigh many tons and too much stress cannot be put on upon the safety of the inspector and others when testing the stopping ability of such vehicles. These tests must be conducted with extreme care in order to prevent possible skidding, jackknifing, load shifting, and overturning. In particular extreme care should be used in testing liquid, cargo-carrying vehicles under partially loaded conditions because of the sudden surging of the cargo. b. Practicality - A thorough brake inspection would probably include looking at the inside of the brake assembly, which is relatively easy when checking passenger vehicles. The removal of wheel hubs and drums from large commercial vehicles, however, is another matter and usually is impractical at an inspection station. A sensible approach would, therefore, probably not include the removal of a hub and drum from the axle unless strong evidence were present indicating an unsafe condition inside the brake. A thorough check of hydraulic, vacuum, or air systems can normally give him a fair idea of the general condition of the braking system, especially when augmented by a practical performance demonstration. Wheel removal from large vehicles is not only difficult because of size and weight problems, but is further complicated by the lack of assurance that they can be properly returned to the axle. The “pulling” of wheels for brake inspection on heavy vehicles is, therefore, not recommended except when considered mandatory and then only by a highly qualified mechanic. There are twelve inspection procedures for brakes in this section.
