PowerStop AR8653SCR Disc Brake Rotor - Front

Coated front brake rotor

The PowerStop AR8653SCR is a coated disc brake rotor built as a direct bolt-on replacement for the original equipment part. It is engineered for front brake applications on the Chevrolet Colorado, GMC Canyon, and select Isuzu models, with corrosion protection on exposed areas to help preserve appearance behind alloy wheels.

Key features

• Part number AR8653SCR
• Partially coated design with silver epoxy on the hat, outer edge, and vanes
• Vented, full cast construction with a smooth surface
• Mill balanced for consistent operation
• Matches original equipment weight and vane count
• Rust-resistant coating helps protect exposed rotor surfaces

Detailed fitment and design

PowerStop’s coated hat and edge rotor line focuses on OE-style replacement with corrosion resistance where it matters most. This AR8653SCR rotor uses a 279.90 mm outside diameter, 112.00 mm bolt circle, and 6-lug mounting pattern, with nominal thickness of 26.90 mm and discard thickness of 25.70 mm. It is a vented rotor with a smooth friction surface, built to match original equipment performance and specifications for the Chevrolet Colorado, GMC Canyon, and related Isuzu applications. The AR8653SCR is also referenced by interchange numbers 8-89040-374-0 and 89040374.

What this rotor helps address

• Brake pulsation from a worn or out-of-spec rotor
• Corrosion on exposed rotor surfaces
• Uneven braking feel from a damaged friction surface
• Fitment issues caused by incorrect rotor dimensions
• Appearance concerns behind modern alloy wheels

Installation notes and quality assurance

Install as a direct replacement for the original equipment rotor on confirmed front applications. Verify rotor diameter, bolt circle, lug count, and thickness before installation. This rotor is designed to match OE specifications, including weight and vane count, for proper fitment on the listed Chevrolet Colorado, GMC Canyon, and Isuzu applications.
