Bulletin Summary
Customer Satisfaction Program. Certain vehicles may have two potential conditions. First; the front caliper may have been produced out of specification on the caliper clearance to the rotor. This can result in brake drag, reducing brake pad life, and the potential to pull to the right or left. Second; the rear caliper may have been damaged during vehicle assembly. This damage may have caused a microcrack in the rear brake calipers piston. This microcrack can result to a leak path for the brake fluid, eventually illuminating the BRAKE malfunction indicator lamp (MIL). Dealers are to replace both front and both rear brake calipers.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
