Short Summary:
2008 Silverado, Replaced Front Rotors and Pads (115,000 miles), Brake pedal will not build pressure, Pedal basicly goes to the floor, Right front has no air when bleeding, left front has air will not bleed. when truck is running the pedal goes to the floor and very slowly returns to the top.

 

Welcome to the forum. Forgot to cap the brake hose? Consider taking it in for service. You won't be able to bleed it properly without a scan tool that can work the ABS.

 

Hey EinST just out of curiosity is that something you can do with the mighty vacs or the one person bleeder? i had this same thing happen and i mighty vaced it and it seemed to be fine, but now you have me wondering if i should have it redone with the scan tool? biggest fear is loosing braking ability

 

The scan tool is for working the valves in the BPMV when the brake pedal stays soft despite manual bleeding. If your pedal is firm, it isn't necessary unless you're going for a complete fluid change.

 

Ok thanks thank you I was wondering what the scanner did but now that makes sense
