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.

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
laser-etched 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. 25-99-2. 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 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.

 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 after
machining 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. 25-99-2. If recorded Brake
Disc measurement is less than the
minimum thickness, the Brake Disc
MUST be replaced.

Note:
