Proper maintenance and timely replacement of ABS components are critical to ensure consistent performance and safety.
Recognizing ABS Issues
- ABS Light: Indicates a problem, from sensor failure to module issues.
- Braking Problems: Spongy brakes or unexpected ABS activation suggest faults.
- Longer Stops: Increased stopping distances, especially on slick surfaces, signal ABS trouble.
- Noises/Vibrations: Excessive sounds or odd vibrations during braking may point to pump or valve issues.
Replacement Triggers
- Sensors: Replace if diagnostics show faults or physical damage.
- Control Module: Swap out if it fails to process data correctly.
- Valves/Pump: Address wear-related delays in pressure modulation.
Cost Estimates
- Sensors: $100-$300 per wheel, including labor.
- Control Module: $500-$1,000, depending on the vehicle.
- Fluid Flush: $50-$100 every 2-3 years.
Maintenance Best Practices
- Check ABS during routine brake servicing.
- Flush brake fluid regularly to prevent contamination.
- Act quickly on warning lights with professional diagnostics.
Key Takeaway: Proactive maintenance and prompt replacement keep ABS reliable and cost-effective.
