• Vehicle pulling to one side during braking, often indicating a sticking caliper
• Uneven brake pad wear patterns showing caliper malfunction
• Overheating brakes on one side of the vehicle
• Brake drag causing premature wear and reduced fuel economy

Anti-Lock Brake System (ABS) Components

High-mileage Chevrolet vehicles frequently experience ABS-related problems as sensors and control modules age. While ABS issues don’t typically prevent normal braking, they eliminate the safety benefits of anti-lock functionality.

ABS warning signs:

• ABS warning light illuminated on the dashboard
• Loss of ABS function during emergency braking situations
• Erratic brake pedal behavior during ABS activation
• Traction control system malfunctions related to ABS sensor problems

What to Expect During a High-Mileage Brake Overhaul
