Detailed Description

Brake systems depend on every hydraulic component working together, and the caliper piston is one of the parts that directly affects stopping action. Carlson 7793 is built for rear disc brake applications where the piston must transfer fluid pressure into pad movement against the rotor. It fits a range of vehicle-specific rear brake setups, including 2004-2011 Ford Crown Victoria, 2010-2011 Ford Ranger, 2003-2011 Lincoln Town Car, 2005-2011 Mercury Grand Marquis, and 2010 Mazda B4000. This part number, 7793, is also listed for additional rear applications within the same vehicle family.

What It Helps Address

• Brake pedal travel caused by a worn or damaged caliper piston
• Uneven rear braking from piston wear or corrosion
• Poor pad contact with the rotor during braking
• Hydraulic response issues in rear disc brake service
• Brake noise or drag related to caliper piston condition

Installation Notes and Tips

Verify rear brake caliper design and vehicle fitment before installation. Match the piston to the caliper pin kit or boot kit notes listed for your application, such as D1040 or D932 references where specified. Clean the caliper bore thoroughly, inspect seals and related hardware, and bleed the brake system after service to restore proper hydraulic operation.

Quality Assurance

Carlson brake hydraulics parts are engineered for service work where accurate hydraulic movement matters. The 7793 caliper piston is intended for vehicle-specific rear brake applications and follows the brake system requirements outlined by the listed fitment data.
