GMC SONOMA BRAKE HARDWARE PROBLEM

2003 GMC Sonoma • 140,000 miles

I have a 2003 gmc sonoma. I have replaced all the brakes lines and brake hardware. Having problems bleeding the system. I filled the master cylnder with fluid and I can't get it to bleed. Any ideas?

You may have gotten air in master cyl. Try using a pressure bleeder and you may need to use 2-3 qts to bleed it prpperly now if your brake pedal isn't very good after bleeding the brake module modlulator valve mayhave air in it and will need to be bled along withusing a scanner to activate it. So it can be bled.

Thanks for getting back to me. Yes it just dawned on me the master cylnder was empty. I will try that. Thanks again.
