MODELS/YEARS
1986-1987 TORONADO
SECTION: 5B
A production change was made to the front and rear brake linings used on the 1987 Toronado effective at VIN breakpoint 309108..
This change includes a new lining material and extended shoes which eliminate the need for the stainless steel shoe abutment insulators. The new shoe
and lining may be identified by the following methods:
FIGURE 1
Lining Edge Code
The lining edge code, which is stamped in the lining material at the locations shown in Figure 1, may be used to identify the new shoe and lining
assemblies. The new design shoe and lining assemblies use the edge code "DM 128 FE", while early production linings include the edge code "DM 121
FE".
Lining Wear Indicator Color
New design shoe and lining assemblies may also be identified by the color of the lining wear indicator, as shown in Figure 1. New lining kits have a blue
wear indicator, while early production linings include wear indicators which are black or gray.
Disc brake noise may be reduced on models built prior to the above breakpoint by installing the new design linings. These shoe and lining kits are
available from GMSPO using the following part numbers:
