Carlson Disc Brake Caliper Piston P/N:7197

Keep hydraulic pressure moving from the caliper to the brake pads with the Carlson Front Disc Brake Caliper Piston 7197. It serves as a front-position piston for the 1990-1993 Mercedes-Benz 300SL (All), 1990-1993 Mercedes-Benz 500SL (All), 1994-1997 Mercedes-Benz SL320 (All), and 1994-1998 Mercedes-Benz SL500 (All), installing as a replacement for the listed applications.

• Front caliper piston: Cataloged in the front position for the listed Mercedes-Benz SL applications.
• Hydraulic actuation: Transfers brake-fluid pressure inside the caliper bore to the pad, pressing it against the rotor to slow the wheel.
• Multi-piston application: The listed vehicles use eight pistons per vehicle, so order the quantity your calipers require.
• Signs it may need replacing: A piston that sticks, seizes, corrodes, or weeps brake fluid can lead to uneven pad wear or a dragging brake.

Inside a disc brake, this piston sits in the caliper bore and moves outward under hydraulic pressure to clamp the pad. If a seized, pitted, or leaking piston is the cause of your braking complaint, replacing it restores the piston's mechanical job; diagnose the caliper before assuming this is the fault. Replace pistons on both sides of an axle as a matched set for even, balanced braking.
