Product Details

Power Stop drilled and slotted rotors are engineered as a bolt-on replacement for front brake service. The cross-drilled design helps move heat away from the braking surface, while the rounded slot pattern sweeps away gases, dust, and moisture to maintain consistent pad-to-rotor contact. The zinc dichromate coating adds a protective layer against rust, making this a practical choice for drivers looking for a performance-oriented rotor with OE-style fitment. PowerStop JBR577XPR is a direct replacement for front brake applications on 2001-2003 Mazda Protege, 2002-2003 Mazda Protege5, 1993-2002 Mazda 626, 1993-1997 Ford Probe, and 1993-1997 Mazda MX-6.

This part cross-references Centric Parts 120.45048 and Raybestos Brakes 96818 for the same application.

Common Brake Issues It Can Address

• Excess brake fade during repeated stops
• Heat buildup in front brake service
• Surface rust on exposed rotor faces
• Dust and gas buildup between pad and rotor
• Uneven braking feel from worn front rotors

Installation Notes and Tips

Install on the front axle only for the listed vehicles. Verify rotor dimensions, hub fit, and brake pad condition before installation. Because this is a direct OE-fit rotor, no special modifications are needed when used on the confirmed applications. For best results, inspect calipers, pads, and hardware during brake service and follow the vehicle manufacturer’s torque specifications.

Quality Assurance

PowerStop manufactures this rotor with precision drilling, slotting, and zinc plating to support consistent braking performance and corrosion resistance. The direct-fit design follows OE-style dimensions for the confirmed Mazda and Ford applications listed above.
