Rear Left Brake Rotor - 1987 Mustang

The Ford E7ZZ-2C026-A rear rotor services 1987-1993 Fox Body Mustangs equipped with rear disc brakes, including the LX 5.0 and GT models featuring the E7TE 5.0L engine. This solid, non-ventilated design integrates a parking brake drum inside the rotor hat, requiring inspection of the internal shoe hardware and drum surface for rust grooving during replacement. When installing Motorcraft BRR259 equivalents or units bearing E7TA casting marks, thoroughly clean the axle hub mating surface and check axle shaft endplay to prevent runout-induced pulsation common to this floating design. The rotor slides over the 4-lug axle shaft flange, retained by wheel studs. Junkyard hunters should verify the casting code—earlier 1979-1986 models used smaller 10-inch brakes, while the 1993 Cobra utilized unique vented rear rotors with thicker hats. Always replace in axle pairs, torque caliper bracket bolts to 65 ft-lbs, and verify parking brake adjustment before road testing.
