Subject: Brake caliper bracket identification
Vehicles Involved: 2002-2005 Chevrolet Trailblazer, 2002-2005 GMC Envoy,
2004-2005 Buick Rainier, Oldsmobile Bravada, Isuzu Ascender
Condition: Caliper bracket
Repair Procedure: There are two calipers listed for the above platforms, FRC11237 and FRC11237A.
Both calipers are physically the same except that the bracket is different.
The change to the bracket was made to accommodate the larger rotor diameter.
Caliper FRC11237 will fit most platforms with the long wheel base or with extended cab.
The bracket of the FRC11237 can be easily identified with a protruding
tab as compared to the FRC11237A where the tab is even with the bracket.
One other detail is the distance between the mounting holes
and the slider pin, the distance of FRC11237 is 3 inches as compared to
the dimensions of the bracket supplied with FRC11237A, the distance is
3.250".
