Carlson Disc Brake Caliper Piston P/N:7199
$24.99
Keep firm, even pressure at the rear wheels with the Carlson Disc Brake Caliper Piston (P/N 7199). Seated inside the rear brake caliper, the piston transfers hydraulic pressure from the brake fluid to the pad, pushing the pad against the rotor each time you apply the brakes. It fits the rear brakes on a range of Mercedes-Benz sedans and coupes, installing as a direct-fit replacement for the listed applications: the 1985 and 1992-1993 300SD, 1986-1987 300SDL, 1988-1993 300SE, 1988-1991 300SEL, 1991 350SD, 1990-1991 350SDL, 1986-1991 420SEL, 1986-1991 560SEC, and 1986-1991 560SEL (all engines).
- Rear caliper function: converts hydraulic brake-fluid pressure into the clamping force that presses the pad against the rotor.
- Direct fit: designed for the rear caliper on the listed Mercedes-Benz applications.
- Quantity: the Buyer's Guide lists four per vehicle for these applications — confirm the count for your car.
- Signs it may need replacing: brake-fluid seepage at the caliper, a sticking or dragging brake, or uneven pad wear.
If a corroded, scored, or seized piston is the cause of a dragging brake or fluid leak, this piston replaces it. Diagnose the underlying cause before replacing. As a best practice, service the pistons and calipers on both wheels of the same axle together for even, balanced braking. Manufacturer part number 7199.

What are signs a caliper piston needs replacing?
Brake-fluid seepage at the caliper, a sticking or dragging brake, or uneven pad wear can be signs. Diagnose the cause before replacing, as these symptoms have other possible causes.
Should I replace both sides?
Best practice is to service the pistons and calipers on both wheels of the same axle together for even, balanced braking, though it's sold as an individual piece.
