Why do my brakes not work after bleeding them?
System leak You are correct to bleed the brakes, the most likely cause of the soft pedal is trapped air inside the hydraulic brake fluid system. The pedal will feel soft and ineffective until the pads and rotors bed in (surfaces mate). This is normal and test-driving and braking lightly will solve the poor pedal feel.
What happens if you don’t get all the air out of brake lines?
It won’t get better on its own, and it could get worse – eventually, a bunch of small air bubbles in the line will join together to become one big, dangerous bubble. So your brakes won’t have their normal pressure – and they could fail entirely, McGraw says.
