Brake warning light is on Brakes make a grinding sound or a high-pitched squeak. Brakes are built to be relatively quiet When braking, your vehicle pulls to one side Brake pedal is either too spongy or too hard You feel a pulsating or vibrating when you brake You detect the odor of burnng brakes Your brake pedal goes down too far Every 3, miles, along with your oil change.
Your brakes are critical to the safety of your vehicle. If you have any questions or concerns about them, call us at Clutch Problems Clutch problems can occur at almost any mileage and for a wide variety of reasons. When the clutch pedal is released and the clutch disc starts to rub against the flywheel and pressure plate, it generates friction and heat.
Is Your Clutch Acting Up?

The friction material on the disc becomes worn and pressure starts to drop, causing it to slip. Clutch issues may be caused from an oil leak or a bad driveshaft, motor mount, linkage, hydraulic system, flywheel, mounting or worn parts. Quality parts are very important because of load and continual use. No one likes to drive a car that chatters.
Clutch repair consists of removing the transmission or transaxle, plus the related systems, to enable access.

Peddle Truck or Shuttle Truck Terms for the city delivery trucks owned by a long-distance hauler.
Percent of Grade The figure used in computing the power requirements of a truck. Usually taken at the steepest grade a truck will be required to climb on its route. Percent of grade is determined by dividing the height of a hill by its length. Pintle Hook Hook mounted on a truck or semi-trailer used to couple a full trailer. A small PTO driving gear in the transmission gives a low pitch line velocity; a larger gear gives a correspondingly higher pitch line velocity.
May be equipped with hydraulic cylinders to tilt and slide platform. Ply Rating A standard unit of tire casing strength, based on the strength of cotton plies. This term is used to indicate the load-carrying ability of a given tire. It is an index of tire strength and does not necessarily represent the number of cord plies in the tire.

Used for transporting long or irregularly shaped loads such as poles, pipes or structural members generally capable of sustaining themselves as beams between the supporting connections.
Power Curve A graphic illustration of maximum output of horsepower and torque at all operating speeds.
These curves are established from data obtained by running a sample engine on an engine dynamometer. Curves are established using bare operable engine and with standard accessories. Net power figures those using standard accessories are used in vehicle performance calculations. Power Divider Usually a small auxiliary gear box or chain-driven device to allow distribution of drive shaft power to several different mechanical devices mounted on the same truck. Power take-offs can be mounted on either a main or auxiliary transmission.
Front-mounted and flywheel-mounted power take-offs are also used in various applications. Power Train All the components that handle the engine power from the truck engine to the driving wheels. This includes transmissions, drive shafts, as well as differentials and driving axles. Push Bumper Device used to push a vehicle, sometimes equipped with a rubber face.

Resisting Bending Moment RBM A calculation used to compare frames of different section modulus and of different material. It is the product of the section modulus times the yield strength of the frame material. The RBM should, therefore, be taken into account whenever frames of unlike material and section modulus are being compared. See Yield Strength. Ridge Pole Member that can be located in center longitudinally on an open top van body to support a tarpaulin in a tent like manner. Rim Pull See Tractive Effort.
Road Rolling Resistance A measure of the retarding effect of the road surface to forward movement of the vehicle.

Does not include a bus designed and sold for operation as a common carrier in urban transportation. This energy is then returned to the drive system during subsequent operations. Semitrailer A trailing unit that is supported in the rear by its own suspension system and at the front by the towing vehicle. This type of unit is sometimes supported by a separate suspension unit with towing provisions thus becoming a full trailer. An exception is the utility-type trailer, house trailer, etc. Serial Number A number stamped on a metal plate by the manufacturer and placed on a component or the vehicle for identification purposes.
Set-back Front Axle The front steering axle is normally as close to the front of the vehicle as the design and wheel and tire size permit. The purpose of moving the axle rearward is to increase loads applied to the front axle and increase maneuverability. Standard type front-axle setting generally enables more economical cab construction and meets axle spread requirements of states using the Bridge Formula.

Short Chain Method of attaching a tow sling to a towed vehicle so that the tow chains support the entire load. Side Rails Upper or lower extensions of the body sides that run longitudinally, front to back. Standard rear-axle gearing is single reduction, i. In certain heavy-duty applications a double reduction is desirable. This permits a greater gear reduction in a smaller gear case, thus allowing better road clearance and more compact design.

Snatch Block A single or multiple pulley used to reduce cable load or change cable direction. Spacer Block Used in conjunction with 4x4 wood beam to provide additional clearance between the tow bar, chains and body of the vehicle.
