Continue driving the vehicle for five to ten minutes with limited braking if possible (allowing brakes to cool).

Repeat Step 2, brake drift evaluation.

Return to dealership, making several "snubs" along the way. These snubs are moderate brake applies from 50 mph to 30 mph, or 40 mph to 20 mph. The object is to retain the heat generated from braking in the brakes so brake drag measurements can be taken during the following brake evaluation.

3.    If the vehicle did drift, perform the Brake System Evaluation test.

BRAKE SYSTEM EVALUATION

NOTE:    IT IS IMPORTANT TO PERFORM THE BRAKE DRAG TORQUE MEASUREMENT ON THE VEHICLE IMMEDIATELY FOLLOWING THE ROAD TEST (BRAKES MUST BE HOT).

WARNING:    USE EXTREME CAUTION WHEN HANDLING THE WHEELS AND BRAKE COMPONENTS WHEN PERFORMING BRAKE DRAG TORQUE MEASUREMENTS. THESE COMPONENTS WILL BE VERY HOT.

**NOTE:    THE LAST BRAKE APPLY BEFORE PERFORMING THE BRAKE DRAG TORQUE TEST (STEP 3) SHOULD BE MADE WITH THE LEAST PEDAL TRAVEL POSSIBLE SO THAT BRAKE PRESSURE IS AT A MINIMUM.**

1.    On 4X4 vehicles that DO NOT have a functioning axle disconnect, shift the transfer case into neutral.

2.    Raise the vehicle on an appropriate lift.

3.    Measure the Drag Torque of each front hublrotor assembly. The measurement should be taken with either a dial or beam type foot pound torque wrench and the rotation must be in a forward direction (Right Side = clockwise - Left Side = counter clockwise).

a.    For all 4X2 vehicles and 4X4 vehicles equipped with the Dana 44 front axle (all 1500 series 4X4 and 7500 lb. GVW 2500 series 4X4), the measurement will be taken with a torque wrench attached to a lug nut. The torque wrench must be perpendicular to the spindle.
