46 17 03 November 21, 2017 2015173 Supersedes Technical Bulletin 46-16-07 (V461607) dated August 23,
2016 to include model year 2018 applicability.
Brake Disc Pulsation or Vibration (U.S. Only)
When applying 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 disc 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 disc machining. Improperly
machined brake discs may cause brake pulsation/vibration after several months in service. The servicing facility
will be responsible for these failures.

Technical Bulletin
Procedure:
 Remove wheels and separate brake calipers from carrier as outlined in Repair Manual Group 44 – Wheels,
Tires, Vehicle Alignment and Group 46 – Brakes – Mechanical components in Elsa.
Brake Disc Inspection
A detailed brake disc inspection is needed to determine if the brake disc should be machined or replaced.
 Inspect brake disc friction surfaces on both sides of the brake disc for:
 Severe discoloration (bluing)
 High heat surface damage (raised hard spots)
 Visible cracks
Brake discs showing any of the above described conditions are NOT serviceable. Parts must be replaced in
accordance with the Volkswagen Warranty Policy and Procedure Manual.

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

 Measure the brake disc thickness in 4 locations using either the Pro Cut International™ disc thickness
measuring tool Part No. 50-902 or the Hunter Engineering Company disc thickness measuring tool Part No. 2599-2. Measurements MUST be taken at the same distance from the brake disc outer circumference to ensure
consistency.

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

Brake Disc Machining
Note:
All brake discs must be machined.
Recommended on-car brake lathes are either the PRO-CUT International ™ PFM 9.0, or the Hunter Engineering
Company model OCL 400. This design of brake lathe will produce a surface quality which will provide proper brake
performance without a brake pad to brake disc break-in period.
To ensure that a high quality brake disc finish is produced, brake lathe cutting tools must be maintained as
directed by the lathe or tool manufacturer.

Technical Bulletin
 Follow the brake lathe
manufacturer’s instructions for set-up
and machining.
 Wash the brake disc with a soap and
water solution upon completion of
resurfacing to remove all machining
particles.

Technician must record the final
thickness measurements on the back of
the repair order.
 Re-measure brake disc thickness in 4
locations using either the Pro Cut
International™ disc thickness
measuring tool Part No. 50-902 or the
Hunter Engineering Company disc
thickness measuring tool Part No. 2599-2. If recorded brake disc
measurement is less than the
minimum thickness, the brake disc
MUST be replaced.

Note:
Always replace brake discs in pairs (front axle or rear axle). Do not replace all 4 brake discs unless it is required.

 Measure brake disc lateral run out
using Pro Cut Disc Lateral run out
measuring kit Part No. 50-700FC or the
Hunter Disc Lateral run out measuring
kit Part No. 25-128-2 with a dial
indicator.
 Run out must not exceed 0.1mm.
 If brake disc exceed the 0.1mm
specification replace the applicable
brake discs.
