Owner’s Guide
Over time, a subtle loss of performance may take place; therefore, it is important to establish the standard with a new vehicle.
The Periodic Brake Performance Test should be performed regularly as an evaluation of braking system performance. It is
useful as a method of identifying subtle loss of performance over time.
PERIODIC BRAKE TEST FOR MECHANICAL BRAKES
The purpose of this test is to compare the braking performance of the vehicle to the braking performance of new or ‘known to
be good’ vehicles or to an established acceptable stopping distance. Actual stopping distances will be influenced by weather
conditions, terrain, road surface condition, actual vehicle weight (accessories installed) and vehicle speed. No specific braking
distance can be reliably specified. The test is conducted by latching the park brake to eliminate different pedal pressures and
to include the affects of linkage mis-adjustment.
Establish the acceptable stopping distance by testing a new or ‘known
to be good’ vehicle and recording the stopping location or stopping dis-
tance. Several vehicles should be tested when new and the range of
stopping locations or distances recorded.
Drive the vehicle at maximum speed on a flat, dry, clean, paved surface.
Quickly depress the brake pedal to latch the parking brake at the line or
marker in the test area and remove foot from pedal. The vehicle should
stop aggressively. The wheel brakes may or may not lock. Observe the
vehicle stopping location or measure the vehicle stopping distance from
the point at which the brakes were latched. The vehicle should stop
within the ‘normal’ range of stopping distances. If the vehicle stops more
than 4 ft. (1.2 m) beyond the acceptable stopping distance or pulls to
one side, the vehicle has failed the test and should be tested again.
If the vehicle fails the second test, it should immediately be removed
from service. The vehicle must be inspected by a qualified mechanic
who should refer to the TROUBLE SHOOTING section in the Techni-
cian’s Repair and Service Manual.
Rear Axle
The only maintenance required for the first five years is the periodic inspection of the
rear axle for lubricant leakage. Unless leakage is evident, the lubricant need only be
replaced after five years. Refer to the Service and Repair Manual for the fluid replace-
ment procedure.
CHECKING THE LUBRICANT LEVEL
Clean the area around the check/fill plug and remove plug. The correct lubricant level is
just below the bottom of the threaded hole. If lubricant is low, add lubricant as required.
Add lubricant slowly until lubricant starts to seep from the hole. Install the check/fill plug.
In the event that the lubricant is to be replaced, the oil pan must be removed or the oil
siphoned through the check/fill hole.
