PowerStop JBR578XPR Disc Brake Rotor Set - Rear

Rear Drilled and Slotted Brake Rotors

PowerStop JBR578XPR is a rear disc brake rotor set built for direct OE fitment on select Mazda, Ford, and Mazda applications. The drilled and slotted surface helps manage heat, clear dust and moisture from the friction area, and maintain consistent rotor contact in demanding braking conditions.

Compatible With rear brake service on 2001-2003 Mazda Protege, 2002-2003 Mazda Protege5, 1993-1997 Ford Probe, 1993-1997 Mazda 626, and 1993-1997 Mazda MX-6.

Key Features

• Precision cross-drilled design for improved cooling under repeated braking
• Rounded slots help sweep away gases, dust, and moisture from the rotor face
• Silver zinc dichromate plating resists rust and corrosion
• Direct OE fit for straightforward replacement on the listed rear applications
• Solid rotor construction with a slotted X drilled surface type
• 5-lug mounting pattern with a 113.80 mm bolt circle diameter

Product Line Details

Power Stop’s drilled and slotted rotor line focuses on thermal management and surface cleaning. For drivers replacing worn rear rotors on a Mazda Protege, Mazda Protege5, Ford Probe, Mazda 626, or Mazda MX-6, this line provides an OE-style fit with added venting and corrosion protection for everyday driving and harder braking use.

Detailed Description

PowerStop JBR578XPR rear brake rotors are engineered around an 8.00 mm nominal thickness, 10.30 in. outside diameter, and 1.60 in. overall height. The solid rotor design and slotted X drilled surface support stable braking performance while the zinc-plated finish helps protect the rotor from rust during normal exposure to road moisture and debris. This part cross-references Bosch 96319 and Centric Parts 120.45049 for the same application.

Common Brake Issues This Rotor Can Address

• Brake fade during repeated stops or downhill driving
• Rotor surface rust from moisture and road exposure
• Dust buildup on the rotor face
• Uneven friction contact caused by heat and contamination
• Worn rear rotors that no longer meet service thickness limits

Installation Notes and Tips

Verify rear fitment by year, make, model, and position before installation. Confirm the rotor dimensions match the vehicle’s OE specifications, including the 113.80 mm bolt circle diameter and 5-lug pattern. Inspect pads, calipers, and hub surfaces during brake service so the new rotor seats cleanly and performs as intended.

Quality Assurance

PowerStop manufactures this rotor pair as a direct replacement part with OE-style fitment and corrosion-resistant plating. The drilled and slotted design is intended to support consistent braking performance and long-term service in the listed rear applications.
