Detailed Description

PowerStop JBR1389XPR is engineered as a bolt-on rear brake rotor replacement for select Toyota and Lexus applications. The cross-drilled pattern helps manage heat during demanding stops, while the rounded slots sweep away gases, dust, and moisture to maintain a cleaner pad-to-rotor interface. The zinc dichromate finish adds corrosion resistance for long-term service exposure. This rotor set is a practical choice for drivers servicing a Toyota Sienna, Toyota Highlander, Lexus RX350, or Lexus RX450h with rear rotor wear or surface degradation.

This part cross-references Centric Parts 120.44166 for the same application.

• Brake pulsation caused by worn or uneven rear rotors.
• Reduced braking consistency from heat buildup.
• Surface rust and corrosion on the rotor face.
• Dust and moisture buildup that affects pad contact.
• Rear brake service needs on select Toyota and Lexus vehicles.
