What This Part Helps Address

• Front brake caliper piston wear or scoring
• Brake fluid leakage at the caliper piston area
• Uneven brake pad contact caused by piston damage
• Sticking or restricted caliper piston movement
• Brake service on GM vehicles with the listed piston references

Installation Notes

Confirm the original piston reference number, caliper design, and front brake application before installation. Match the vehicle year, make, model, and notes exactly, especially on 2002-2003 Cadillac DeVille applications with the heavy duty brake exception and on Saturn Relay and Pontiac Montana listings that specify a steel piston.

For best results, inspect the caliper bore, seals, and brake fluid condition during service. On vehicles such as the Buick LaCrosse, Pontiac Grand Prix, and Chevrolet Impala, verify the front caliper configuration against the OE reference before assembly.

Quality Assurance

Carlson brake hydraulics parts are cataloged for direct application matching across the listed GM front brake platforms. Part number 7846 is identified for use with the specified OE-style piston references and fitment records.
