Rear Right Brake Caliper - 1987 Mustang

The rear right brake caliper for the 1987 Ford Mustang GT (Fox platform) carries primary OEM reference E7ZZ-2552-A, though service supersessions often cross to F1ZZ-2552-A or display legacy E6ZZ-2552-A casting marks. This single-piston sliding unit directly interchange with 1986-1993 Mustang GT models equipped with factory rear disc brakes, plus 1987-1988 Thunderbird Turbo Coupes utilizing identical Fox-platform architecture. When junkyard hunting, verify the integrated parking brake actuator isn't seized—a common failure point where the internal cam mechanism corrodes solid after three decades. Inspect slide pins for pitting; they must move freely or the caliper will drag and overheat pads. Installation requires carefully compressing the piston while manually aligning the parking brake cam against spring tension to avoid damaging the mechanism. Thread sealant is mandatory on the inverted flare brake line fitting. Critically, avoid 1993 Cobra units which feature larger 73mm pistons incompatible with GT brackets unless upgrading both sides simultaneously.
