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.
Procedure:
 Remove Wheels and separate Brake Calipers from Carrier as outlined in Repair Manual Group 44 in
Elsa.
Brake Disc Inspection
A detailed Brake Disc inspection is needed to determine if the Brake Disc should be machined or
replaced.
 Inspect the Brake Disc friction surfaces on both sides of the Brake Disc for:
 Severe discoloration (bluing)
 High heat surface damage (raised hard spots)
 Visible cracks
Note:
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.
Please see the example pictures below of damage NOT covered under warranty.

 Measure the Brake Disc thickness in 4 locations using a digital or mechanical caliper/micrometer.
Measurements MUST be taken at the same distance from the brake disc outer circumference to
ensure consistency.
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 after machining,
replace the Brake Disc.

Brake Disc Machining
Note:
All Brake Discs 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 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.
