Hello everyone. Got a problem with the brake pedal on my 2000 c70 going almost to the floor. I have bled and re-bled the brakes. The pads are practically new front and rear. The pedal stays where I push it with no bleeddown. but this much free travel is scary. Could this be the master cylinder, ABS pump or something else? Is the master cylinder rod adjustable. I ask this before I remove it. If anyone has solved this problem before, your input is greatly appreciated.

 

Might be the brake booster. Had 1 go bd on my Chevy truck, brake pedal did same thing.

 

Thanks, I may have to change it to eliminate the possibility.
