How to Change the Rear Brake Pads on a Mercedes E-Class W211

Detailed instructions - Replacing the rear brake pads on a Mercedes E-Class W211 requires special attention because the vehicle is equipped with the SBC (Sensotronic Brake Control) system, an electro-hydraulic braking system that maintains pressure in the fluid even when the engine is off. Before any work, it is mandatory to deactivate the SBC with a diagnostic tool (like the Launch Creader Elite, which can be found on Ali Express with code 1005012953589911 for $123.67 with free shipping) to prevent the system from being accidentally activated during the work, causing serious injury or damage to the system. Start by loosening the wheel bolts, lifting the car, and removing the rear wheel. Disconnect the wear sensor connector, remove the caliper guide caps, and unscrew the caliper mounting bolts (HEX key H7). Hang the caliper from the suspension with a wire, without disconnecting the brake line. Remove the old pads and the bracket. Use the appropriate tool to push back the caliper piston. Clean the surfaces with a brush and brake cleaner, apply anti-squeal paste to the new pads, and install them with the friction material facing the rotor. Reinstall the bracket (20.7 lb-ft), the caps, the wear sensor, and the caliper (18.4 lb-ft). Finally, reactivate the SBC with the diagnostic tool, pump the brake pedal several times to reposition the pads, check the fluid level, and reinstall the wheel (96.3 lb-ft).
