PowerStop EBR1224XPR Disc Brake Rotor Set - Front

Front Brake Rotor Upgrade for BMW Z4

PowerStop EBR1224XPR is a front disc brake rotor set built for 2009-2016 BMW Z4 applications. It uses a drilled and slotted surface with a zinc-plated finish to support cooler braking, cleaner pad contact, and better corrosion resistance in daily driving and demanding stops.

The Power Stop front drilled, slotted and zinc plated brake rotor pair is part of a rotor line focused on direct OE fitment with performance-oriented surface design. For BMW Z4 front brake service, this rotor set provides a bolt-on replacement that follows the original mounting pattern and dimensions without special modifications.

Detailed Description

PowerStop EBR1224XPR is engineered as a front brake rotor replacement for the BMW Z4 from 2009 through 2016. The drilled holes help move heat away from the braking surface, while the rounded slots clear away gases, dust, and moisture to maintain consistent pad-to-rotor contact. The zinc dichromate coating adds a corrosion-resistant layer that helps protect the rotor surface from rust.

This rotor is a full-cast, vented design with OE-style fitment dimensions, making it a practical choice for BMW Z4 front brake service when the original rotors need replacement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Part number EBR1224XPR is also identified with interchange references 120.34120 and 45534.

Common Issues This Rotor Can Address

• Brake fade during repeated stops or higher-heat driving
• Surface rust on exposed rotor faces
• Uneven pad contact caused by worn or glazed rotor surfaces
• Noise or vibration related to rotor wear
• Reduced braking consistency from contaminated friction surfaces

Installation Notes and Tips

Fits 2009-2016 BMW Z4, front. Confirm rotor dimensions, hub fitment, and brake system configuration before installation. Clean the hub mounting surface thoroughly before installing the rotor to help prevent runout concerns. Inspect pads and caliper hardware condition at the same time, since rotor replacement is often performed as part of a complete front brake service. Part number EBR1224XPR should be matched to the vehicle’s front axle application only.

Quality Assurance

Power Stop manufactures this rotor with OE-fit dimensions, vented full-cast construction, and a rust-resistant zinc coating to support consistent service life and dependable braking performance on BMW Z4 front applications.
