Compatibility: For 1 Series F40; 2 Series F44/F45/F46; X1 F48; X2 F39; and F54/F55/F56/F57/F60. What it is: A brake pad wear sensor that monitors pad condition and flags when replacement is due. Key benefits: - Early warning: Warns before pads are excessively worn to prevent sudden brake failure and support timely maintenance and safe driving. - Maintains braking performance: Helps ensure reliable braking response by monitoring pad wear and triggering alerts when action is needed. - Protects rotors and reduces costs: Warns before complete wear to avoid metal-to-metal contact, extending component life and reducing costly repairs. Use scenarios: - Routine service: Signals during scheduled maintenance when pads reach the replacement threshold. - Long highway trips: Provides advance warnings to ensure safe braking on extended drives. - Fleet operations: Helps managers schedule timely replacements and maintain consistent braking performance across vehicles.
