• Brake hardware with PTFE coating, vulcanized rubber, and stainless steel construction

Product Line Details

DFC Complete Brake Kits are packaged to simplify front brake service by combining the rotor, pad, and hardware components needed for a single axle repair. The GEOSPEC rotor line focuses on corrosion protection and OE-level machining, while the 5000 Advanced pad line is formulated for stable friction performance and quieter operation in demanding daily-use and commercial-duty braking systems.

Detailed Description

Part number 4512-48076 is engineered for front axle service on select Chevrolet P30 and GMC P3500 models, along with other GM heavy-duty van and chassis applications shown in the fitment list. The coated rotors are machined to tight tolerances, balanced where required, and finished with a non-directional surface to support consistent contact and quieter stops. The ceramic pads are post-cured and scorched for stable friction characteristics, while the included hardware is designed to restore proper caliper movement and spring tension.

This kit is a practical choice for front brake service on Chevrolet P30 front brake replacement, GMC P3500 front disc brake repair, and other compatible GM dual rear wheel applications where corrosion resistance, pad stability, and OE-style fit are important. Part number 4512-48076 is built to address wear-related brake noise, uneven pad wear, and reduced braking consistency on older front brake systems.

What This Kit Helps Address

• Brake noise from worn or corroded hardware
• Uneven or premature pad wear
• Rotor rust and surface corrosion
• Reduced braking smoothness from aged components
• Longer service time caused by unprepared rotor surfaces

Installation Notes and Tips

Install on the front axle only for the listed applications. The rotors are shipped dry and ready to install, which eliminates the need to clean off oil before assembly. Inspect calipers, slides, and hub surfaces during service, and verify the hub-hole and brake configuration notes for the specific Chevrolet P30, GMC P3500, or other GM chassis application before installation.

Quality Assurance

DFC rotors are manufactured to OE specifications, inspected for critical dimensions, and covered by a 12-month warranty against defects in material and workmanship. The brake pads are post-cured for stable friction performance, and the hardware kit is built with OE-style attention to form, fit, and function.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
