- Fits the front axle: cataloged for the front caliper position on the listed vehicles.
- Per-application quantity: the listed applications use two — order accordingly.
- Signs it may need replacing: fluid seepage past the piston seal, a piston that sticks or is corroded/pitted in the bore, or uneven pad wear traced to that caliper.
Diagnose the cause of any brake concern before replacing, since these symptoms can have other sources. Manufacturer part number 7161.
