Date:

Corporate Bulletin No.: 135017
ASE No.: A5
Subject:
FRONT DISC BRAKE CALIPER BOLT BORE CORROSION
Model and Year:
1990-92 CAVALIER, CORSICA AND BERETTA
Condition:
Some 1990-92 J/L cars may experience a condition of a caliper not sliding freely or moving on the mounting bolts inward toward the
center of the vehicle.
FIGURE 1
Cause:
This condition is due to corrosion in the caliper mounting bolt area (See Figure 1) caused by contaminates seeping past the mounting
bolt rubber bushing.
Correction:
Inspect the caliper suspension mounting bolts and sleeves for corrosion. Also, inspect the bushings for cuts, nicks and/or excessive
wear. If damage to either part is found, replace with new parts.
IMPORTANT:
Do Not attempt to polish away corrosion from the bolt or sleeve assemblies.
Lubricate the bushing bore with silicone grease, contained in Bushing Kit, P/N 18017226 or equivalent and install bolt and sleeve
assembly. The bolt and sleeve assembly should slide through the bushing without the use of mechanical assistance. If the force
required to slide the bolt and sleeve exceeds hand assembly pressure, remove the bushings and inspect the mounting bores for
corrosion.
*
If bores show signs of corrosion, clean the bores with a one inch wheel cylinder honing brush.
IMPORTANT:
Replace rubber bushings with new parts contained in service kit, P/N 18017226 whenever they are removed from housing.
Parts are currently available from GMSPO.
