Why Use a Scan Tool for Bleeding GM ABS Brakes?
Traditional brake bleeding methods involve manually opening and closing bleed valves while someone pumps the brake pedal. While this method can be effective, it can be time-consuming and messy. More importantly, modern GM vehicles, equipped with ABS, require a more sophisticated approach to ensure all air is purged from the system.
A scan tool specifically designed for GM vehicles with ABS bleed capability offers several advantages:
- Activate ABS Module: These tools can command the ABS module to cycle through various modes, allowing for a more thorough bleed.
- Precise Control: Scan tools offer precise control over the ABS system, ensuring that air is effectively removed from all channels.
- Diagnostic Capabilities: Beyond bleeding brakes, these tools can diagnose other ABS issues, saving you time and potential headaches.
