Carlson Disc Brake Caliper Piston P/N:7959
Carlson 7757 front brake caliper piston for the 1988-1992 Audi 80 and other vehicles uses brake fluid pressure to push the brake pads against the rotor. The piston matches OE quality specifications.
Fluid at the caliper, a pad that drags, uneven pad wear or a pull to one side can mean the piston is worn or sticking. A sticking caliper slide, a worn rotor or tired pads can be behind the same signs, so find the cause before you buy a piston. Front pistons are best swapped as a pair, and this listing is one piston.
This piston is listed for a wide range of Audi models, and the 1988-1992 Audi 80 Quattro and the 1988-1992 Audi 90 Quattro are included.
