PowerStop EBR859SCR Disc Brake Rotor - Front

Overview

The PowerStop EBR859SCR is a front disc brake rotor built as a direct bolt-on replacement for original equipment. It is designed for Mercedes-Benz applications that need OE-style fitment, smooth braking surfaces, and corrosion protection in exposed areas.

This rotor fits Mercedes-Benz C230, C240, C280, E300, and SLK230 front applications. The EBR859SCR also cross-references Mercedes-Benz part numbers 203 421 03 12 and 210 421 07 12 for the same application.

Key Features

• Partially coated rotor with silver epoxy on the hat, outer edge, and vanes.
• Rust-resistant coating helps protect exposed metal surfaces from corrosion.
• Vented, full cast construction for OE-style brake performance.
• Mill-balanced design for consistent operation.
• Smooth friction surface with OE-matched weight and vane count.

Product Details

PowerStop’s coated hat and edge rotor line focuses on direct replacement fitment with corrosion protection where it matters most. The EBR859SCR uses a vented, full cast design and a smooth surface finish to match original equipment specifications while helping preserve appearance behind alloy wheels. For Mercedes-Benz C230, C240, C280, E300, and SLK230 front brake service, this rotor is built to install without modification when the application matches the listed fitment.

Common Issues It Can Address

• Corrosion on the rotor hat, edge, or internal vanes.
• Brake pulsation caused by worn or out-of-spec rotors.
• Reduced braking consistency from rotor wear.
• Visible rust behind open-style alloy wheels.

Installation Notes

Verify rotor diameter, thickness, bolt circle, and hub fitment before installation. This rotor has a 288 mm outside diameter, 25.00 mm nominal thickness, 22.40 mm discard thickness, and a 112 mm bolt circle with five lug holes. Confirm the vehicle’s front brake configuration against the listed fitment for Mercedes-Benz C230, C240, C280, E300, and SLK230 applications.

Quality Assurance

PowerStop designs this rotor to match original equipment performance and specifications, including weight and vane count, for confirmed fitment. The coated surfaces are intended to help resist corrosion in areas prone to rust.
