Mustang GT V8-4.6L SOHC VIN X (1998)
Brake Rotor/Disc: Initial Inspection and Diagnostic Overview
Brake pulsation (brake roughness) that is present during brake application is caused by either foreign material build-up or contamination on the rotor
brake surface or uneven lateral runout.
If brake pulsation (brake roughness) is present, attempt stopping vehicle with transmission in the NEUTRAL position. If the pulsation (roughness) is
gone, the drivetrain should be inspected. If pulsation (roughness) remains, stop vehicle from 48 km/h (30 mph) using parking brake. If pulsation
remains, inspect rear brakes. If pulsation is gone, inspect front brakes.
