Detailed Description

AR8142XPR is engineered for rear brake service on the Ford Mustang from 1994 through 2004. The cross-drilled pattern helps move heat away from the braking surface, while the rounded slots sweep away gas, dust, and moisture to maintain a cleaner friction contact patch. The zinc dichromate coating adds a protective layer that helps resist surface rust on exposed rotor areas.

This rotor set is a practical choice for Mustang owners looking for a rear brake rotor replacement with a performance-oriented surface finish and OE-style fitment. The PowerStop AR8142XPR is also referenced by Centric Parts 120.61042 and Continental 66448 for the same application.

Common Brake Issues It Can Address

• Brake fade during repeated stops or higher-heat driving
• Surface rust on exposed rotor areas
• Dust and moisture buildup on the braking surface
• Uneven pad contact caused by worn or glazed rotors
• Reduced braking consistency from aging rear rotors
