Known issues on the 1988 Brougham. Nine recalls are on federal record for this model year. Most concern the rear wheel brake cylinders: on the sedan, limousine and stretch-conversion limousine variants, the cylinders were sized too small to meet the stopping-distance requirements of FMVSS 105 with the power brake assist unit inoperative, lengthening stopping distance. A separate recall covers the cruise control servo, where a small nylon bushing can slip out of place and cause an intermittent, unexpected increase in engine speed or dieseling after the ignition is shut off. Another covers the rear seat belt shoulder retractor, which may fail to lock under the acceleration required by FMVSS No. 209, raising injury risk to that occupant. Owners have filed 2 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're inspecting the rear brake cylinders, checking the cruise control servo bushing, or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 1988 Brougham.
