Brake bleeding on and off?

Hi,

There is a chance the master cylinder failed during the bleeding process. Under normal use, the plungers only travel a small distance within the bore. When you bleed the brakes and the pedal goes to the floor, often the plungers are damaged by dirt or corrosion in the untraveled area.

So, here is what I need you to do. Pump the brakes (engine off) until you get a solid brake pedal. Hold pressure for an extended period of time and see if the pedal slowly goes down.

If it doesn't, you likely got air into the hydraulic control unit which requires an automated bleed procedure with a scan tool.

Let me know about holding pressure.

Take care,

Joe
