Keep your front brake pads seated, quiet, and moving freely with the Dynamic Friction Company Disc Brake Hardware Kit (P/N 340-63012). This front disc brake hardware kit is a direct-fit replacement for the 1985 Mercedes-Benz 300SD, 1986-1987 300SDL, 1988-1991 300SE, 1988-1991 300SEL, 1991 350SD, 1990-1991 350SDL, 1986-1991 420SEL, 1986-1991 560SEC, and 1986-1991 560SEL — see the Buyer's Guide tab for the full engine-level list.
The hardware refreshes the small clips, springs, and retainers that position the pads and control rattle at the front calipers, so a brake job goes back together with fresh, correctly-tensioned pieces instead of worn originals.
Installing fresh hardware alongside new pads helps the pads move evenly and can address noise or uneven wear if worn clips are the cause.
What is included in this kit?
It supplies the front disc brake hardware — the clips, springs, and retainers that position the pads and control rattle at the caliper. Pads and rotors are not included.
Which vehicles does P/N 340-63012 fit?
It's a direct-fit front kit for the Mercedes-Benz 300SD, 300SDL, 300SE, 300SEL, 350SD, 350SDL, 420SEL, 560SEC, and 560SEL. Check the Buyer's Guide tab to confirm your exact year and engine.
Is this a front or rear brake hardware kit?
This is a front disc brake hardware kit, cataloged for the front axle position on the listed Mercedes-Benz applications.
Do I need to replace the brake hardware when I change pads?
It's good practice. Fresh hardware keeps the pads seated and sliding correctly, which helps prevent rattle and uneven wear if the old clips are worn or corroded.
Can worn hardware cause brake noise?
Yes. Worn or rusted clips and springs can let pads rattle or drag. If failing hardware is the cause of the noise, replacing it with this kit addresses it; diagnose the cause before ordering.
