The TRW GIC198 is a crucial component designed to monitor the wear level of your vehicle's brake pads. When the brake pads reach a critical thickness, this indicator will activate, providing a clear audible or visual warning to the driver. Timely replacement of brake pads is essential for maintaining effective braking and preventing damage to other braking system components, such as rotors. This wear indicator serves as an early warning system, helping you avoid potential safety hazards and costly repairs. Ensure your braking system operates at its best by fitting genuine TRW wear indicators. They are engineered to meet stringent quality standards for reliable performance and longevity.
