Carlson 7841 Disc Brake Caliper Piston - Rear

Carlson 7841 Rear Disc Brake Caliper Piston

Carlson 7841 is a rear disc brake caliper piston for vehicles that use disc brakes at the rear axle. It transfers hydraulic brake fluid pressure into clamping force, helping the brake pads press against the rotor during braking.

• Rear disc brake caliper piston for hydraulic brake systems
• Fits 1999-2005 Pontiac Grand Am, rear, compatible with disc brakes only
• Fits 1999-2004 Oldsmobile Alero, rear, compatible with disc brakes only
• Supports proper caliper operation in rear disc brake service
• Carlson part number 7841 for brake hydraulic repair

How It Works

In a disc brake system, the caliper piston is a critical hydraulic component. When brake fluid pressure enters the caliper, the piston moves to apply the pads against the rotor. For Pontiac Grand Am rear disc brake service and Oldsmobile Alero rear disc brake repair, Carlson 7841 provides the piston needed to restore caliper function.

Common Problems It Can Address

• Rear brake caliper piston wear or corrosion
• Uneven pad contact caused by a sticking piston
• Brake drag from a piston that does not retract properly
• Reduced braking response from hydraulic caliper issues
• Service needs during rear disc brake caliper rebuilds

Installation Notes

Verify rear disc brake application before ordering. This part is listed for disc brake systems only on the 1999-2005 Pontiac Grand Am and 1999-2004 Oldsmobile Alero. Inspect the caliper bore, seals, and brake fluid condition during service, and follow the vehicle service procedure for brake bleeding after installation.

Quality Assurance

Carlson designs brake components as part of a complete hydraulic system, with the caliper piston serving an essential role in brake force transfer. Part number 7841 is built for the specified rear disc brake applications and is intended for direct brake hydraulic service on the listed vehicles.
