Service
1.
Use ETKA to verify the vehicle build date and the front brake PR code.
2.
Use this data to determine which scenario applies to the vehicle to perform the correct repair. Only one
scenario can be applied to the vehicle.
Scenario A:
Cars built before June 20, 2011 with PR-1LJ
Scenario B:
• Cars built before June 20, 2011 with PR-1ZT
• Cars built on or after June 20, 2011 but before December 6, 2013 with PR-1LJ
Scenario A
1.
Install the parts listed in the Required Parts and Tools table according to Elsa.
2.
Apply a thin coat of anti-seize (G 052560A2) lubricant to
the guide pins of the front caliper carriers prior to
installing the brake pads (Figure 2).
Figure 2. Caliper carrier guide pins with antiseize (G 052560A2) lubricant applied where the
pads make contact.
3.
