Keep your rear brakes clamping smoothly with the Carlson Disc Brake Caliper Piston 7064, a direct-fit replacement piston for the rear disc brake calipers on the 1986-1990 Acura Legend, 1991-1997 Honda Accord, 1992-1994 Acura Vigor, 1995-1998 Acura TL, and 2006-2022 Mazda MX-5 Miata (all engines). It replaces a worn or corroded piston so the caliper can apply the pads cleanly.
- Rear caliper piston: designed for the rear disc brake caliper on the listed applications.
- Hydraulic actuation: transfers brake-line pressure to the pad backing plate.
- Quantity: the listed applications use two pistons; order the quantity your vehicle requires.
Inside the caliper, hydraulic pressure from the master cylinder acts on the piston, which pushes the brake pad against the rotor to slow the wheel. Signs the original piston may need replacing include a seized or sticking piston, corrosion or pitting on its surface, brake drag, uneven pad wear, or fluid weeping past the caliper seal. If a failed piston is the cause, this part replaces it; diagnose the underlying cause before replacing. For even, balanced braking, service both sides of the axle together as a matched set.
Manufacturer part number 7064.
