Rear Right Brake Flex Hose - 1987 Mustang

The 1987 Ford Mustang Fox Body transitioned to the 'aero' nose while retaining the rear disc architecture introduced in 1986 for GT models. When junkyard hunting for the rear right brake flex hose, target 1987-1993 V8 Mustangs equipped with the E7TE 5.0L HO—avoid 2.3L cars with rear drums. The correct Ford service number is E7ZZ-2A442-A for the right side, superseded by F2ZZ-2A442-A in later catalogs. Inspect the crimped metal collars for corrosion swelling or rust weeping; if the stainless braid shows green corrosion or the rubber is cracked at the fitting entry, pass. During installation, always replace copper washers on the banjo bolt and ensure the retaining clip on the trailing arm bracket is not cracked. Common failures include internal collapse causing rear brake drag, or abrasion damage where the hose contacts the axle housing.
