46-19-02 - Brake Rotor, Vibration / Pulsation (U.S. Only)

When applying the brakes at highway speeds the following symptoms may occur:
 Brake Pedal pulsation
 Vibration felt in Vehicle Body
 Steering Wheel shakes

Technical Background
For brake vibration or pulsation concerns, brake rotor machining is allowed between 6 and 12 months or
6,000 and 12,000 miles (whichever comes first) from the warranty in service date.

Production Solution
No production change required.

Service
Note:
All policies and procedures outlined in this technical bulletin also apply to sublet brake rotor machining.
Improperly machined brake rotors may cause brake pulsation/vibration after several months in service.
The servicing facility will be responsible for these failures.
Procedure:
 Remove Wheels and separate Brake Calipers from Carrier as outlined in Repair Manual Group 44 in
Elsa.
Brake Rotor Inspection
A detailed brake rotor inspection is needed to determine if the brake rotor should be machined or
replaced.
Inspect the brake rotor friction surfaces on both sides of the brake rotor for:
 Severe discoloration (bluing)
 High heat surface damage (raised hard spots)
 Visible cracks
Note:
Brake rotors showing any of the above described conditions are NOT serviceable. Parts must be
replaced in accordance with the Volkswagen Warranty Policy and Procedure Manual.
Please see the example pictures below of damage NOT covered under warranty.

Disc Thickness Measuring
Technician must record the beginning
thickness measurements on the back
of the repair order.
Each brake rotor has the minimum
allowed thickness cast, stamped or
laser-etched into the rotor hub.

 Measure the brake rotor thickness in 4 locations using a digital or mechanical caliper/micrometer.
Measurements MUST be taken at the same distance from the brake rotor outer circumference to
ensure consistency.

Note:
The brake rotor thickness
measurement must exceed the
minimum specification after the
machining process is completed in
order to be re-used. If the brake rotor
thickness measurement does not
meet this requirement after machining,
replace the brake rotor.

Brake Rotor Machining
Note:
All Brake Rotors must be machined.
Recommended on-car brake lathe is the PRO-CUT International ™ PFM 9.2 (or equivalent – can be
locally sourced). This design of brake lathe will produce a surface quality which will provide proper brake
performance without a brake pad to brake rotor break-in period.
To ensure that a high quality brake rotor finish is produced, brake lathe cutting tools must be maintained
as directed by the lathe or tool manufacturer.
