Reseal a leaking front brake caliper and keep hydraulic pressure where it belongs with the Dorman First Stop Disc Brake Caliper Repair Kit D670193. It's a direct replacement for the front calipers on the 2011-2015 Chevrolet Cruze, 2011-2015 Chevrolet Volt, 2012-2015 Buick Verano, 2012-2016 Chevrolet Sonic, 2013-2015 Cadillac ATS, and 2013-2015 Chevrolet Trax (all engines).
Inside the caliper, the piston seal maintains the hydraulic seal between the piston and its bore and helps retract the piston, while the boot keeps dirt and moisture off the piston. If a torn boot or a worn, leaking piston seal is the cause of caliper trouble, this kit replaces those components. Installation hardware, bolts, the pin, and caliper grease are not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.

This part cross-references / interchanges with the following part numbers:
What comes in this repair kit?
It includes one EPDM rubber piston seal and one EPDM rubber piston boot, both black. Installation hardware, bolts, the pin, and caliper grease are not included.
What vehicles does it fit?
The front calipers on the 2011-2015 Chevrolet Cruze and Volt, 2012-2015 Buick Verano, 2012-2016 Chevrolet Sonic, and 2013-2015 Cadillac ATS and Chevrolet Trax. See the Buyer's Guide tab for full details.
What caliper bore size is this kit for?
The seal and boot are sized for a 2.359 in caliper piston bore. The piston boot is 76 mm outside diameter and 48.8 mm inside diameter.
What are signs the seal and boot may need replacing?
Brake fluid seepage at the caliper piston, a sticking or slow-retracting piston, or a torn, cracked dust boot. Diagnose the cause before replacing, since other parts can be involved.
Does one kit service both front calipers?
No. This kit reseals one caliper, and a front axle has two, so many jobs use two kits. It's good practice to service both sides together.
