The Carlson Disc Brake Caliper Piston 7004 does the hydraulic heavy lifting inside your front brake caliper, using brake-fluid pressure to force the pads against the rotor when you press the pedal. It installs as a direct-fit replacement for the listed applications: the 2000-2006 Audi TT [All], 1999-2010 Volkswagen Beetle [All], 1996-2006 Volkswagen Golf [All], and 1996-2005 Volkswagen Jetta [All].
Because friction hardware wears alongside the pads, many brake-service experts replace caliper pistons when the friction material is renewed. If a sticking or corroded piston is the cause of brake drag or uneven pad wear, this replaces it. Sold individually; the listed applications use 2, so order two to service both sides. Country of origin: China.
