What is wrong
ON THE INVOLVED VEHICLES, THE NUTS WHICH ATTACH THE BRAKE MASTER CYLINDER TO THE HYDRO-BOOST UNIT MAY HAVE BEEN OVER-TIGHTENED. THIS COULD HAVE CAUSED STRIPPED THREADS AND CRACKED ATTACHING FLANGES. SHOULD THESE NUTS FAIL, THE PARTS MAY SEPARATE AND LOSS OF SERVICE BRAKES WOULD RESULT.
The fix
Recall repairs are free of charge.
DEALER WILL INSPECT FOR CRACKS IN THE ATTACHING FLANGES; UNITS WITH CRACKS PRESENT WILL BE REPLACED. IF NO CRACKS ARE FOUND, THE STUDS WILL BE REMOVED AND THE HOLES DRILLED OUT. THE UNIT WILL BE REASSEMBLED USING BOLTS AND NUTS IN PLACE OF THE EXISTING STUDS.

A recall means the maker found a safety problem and offers a free fix; it does not mean every unit has the problem. Units affected are as reported by the company. Popular models sell more and so have more recalls and complaints. Official public data; texts are shortened. A dealer can tell whether a single vehicle still needs the repair.
