Carlson Disc Brake Caliper Piston P/N:7953
Carlson 7923 rear brake caliper piston for the 1999-2010 Hyundai Sonata and other vehicles uses brake fluid pressure to push the brake pads against the rotor. Also called a disc brake caliper piston, it matches Original Equipment (OE) quality specifications.
A piston that sticks or leaks can show up as a rear brake that drags, brake fluid around the caliper or uneven pad wear. These signs alone do not prove the piston is the problem, since a worn pad can wear unevenly too. The 1999-2010 Hyundai Sonata takes two. Plan to do both rear calipers at the same time; this listing is a single piston.
The vehicles it fits include the 1999-2010 Hyundai Sonata, the 2001-2010 Kia Optima and the 2005-2010 Kia Sportage. If your car is not named here, look it up in the "Vehicles it fits" section.
