ABS Bleeding Procedure

What it does

• Removes air from the ABS hydraulic unit
• Ensures correct brake pressure modulation
• Restores proper brake pedal feel and braking efficiency

When it is required

• After opening the brake hydraulic system
• After replacing:
• ABS hydraulic unit
• Brake master cylinder
• Brake lines or hoses
• When brake pedal feels soft or spongy

Conditions that must be met

• Brake fluid at correct level
• No external leaks in the brake system
• Compatible diagnostic tool connected
• Ignition ON, engine OFF
• Stable battery voltage

What happens during bleeding

• Diagnostic tool activates ABS solenoid valves
• Pump cycles to move trapped air
• Air is expelled through brake calipers
• Brake fluid flow is monitored

If bleeding is not performed

• Soft or inconsistent brake pedal
• Reduced braking performance
• ABS may not function correctly in emergency braking

After bleeding

• Check brake pedal firmness
• Verify brake fluid level
• Clear brake-related fault codes if present
• Perform a road test at low speed
