Help quiet your rear stops with the BOSCH brake pad set BP986, a rear disc brake pad set from Bosch's QuietCast line. It fits many Mercedes-Benz models as a direct-fit replacement, among them the 2010-2013 Mercedes-Benz S400 and 2007-2011 Mercedes-Benz CLS550. See the "Vehicles it fits" section for the full list and engine details.
- Copper-free friction formula: Uses an advanced aerospace alloy and is compliant with 2025 copper-free legislation.
- OE-style rubber core shim: Pre-attached multilayer shims bond rubber and steel, designed for lower noise, added strength and corrosion resistance.
- PTFE and rubber coated hardware: Helps reduce vibration and noise and helps keep the pads from binding to the caliper.
- Powder-coated backing plate: Helps prevent rust and corrosion for longer pad life.
Bosch engineers formulated and tested the QuietCast friction material, backed by Bosch's OE braking heritage dating to 1927. A protective transfer layer is designed to extend pad and rotor life. Synthetic lubricant is included in all applications to help reduce resistance on the sliding contact points.
Signs rear pads may need replacing include squealing or grinding when braking, reduced braking response, or friction material worn thin. Have the brakes inspected to confirm the cause, and replace the pads on both sides of the rear axle together for even, balanced braking.

Frequently Asked Questions
Are BOSCH quietcast brake pads copper free?
Yes. The QuietCast friction formula in BP986 uses an advanced aerospace alloy and is compliant with 2025 copper-free legislation.
Which axle does BP986 fit?
BP986 is cataloged as a rear pad set for the listed Mercedes-Benz applications, such as the 2010-2013 Mercedes-Benz S400 and 2007-2011 Mercedes-Benz CLS550. See the "Vehicles it fits" section for every application.
Is brake lubricant included with BP986?
Yes. Bosch includes synthetic lubricant in all applications to help reduce resistance on the sliding contact points.
What helps reduce brake noise on these pads?
Pre-attached multilayer rubber core shims and PTFE and rubber coated hardware are designed to reduce noise and vibration. The hardware also helps prevent binding to the caliper.
When should I replace rear brake pads?
Squealing or grinding, reduced braking response, or thin friction material are signs pads may need replacing. Have the brakes inspected to confirm the cause, and replace both rear sides together for even braking.
