I have a 1999 chevy blazer 4x4 with no brakes . It started out having the front brakes only . Didn't realize until I was going to put back brakes on they were not working . Checked all the lines and they are clear to the rear bled the front and now unless the key is off i have no pedal at all . I know the brake booster is working because fluid comes out of all four lines .

 

How did you do the brake bleeding?

I finally got an OBD reader that also allows me to cycle the ABS system to help with the bleeding. In the past the best I could do was a gravity bleed. I'm planning on starting my fall maintenance on the truck in the next week or so and will by trying the ABS cycling for the first time.

 

I just pumped the brake pedal until it was stiff and bled them through the bleeder vales . Was not aware you needed a reader .

 

Here's what I think are all the pages from my 99 service manual on bleeding. (attached)

And, trying to get a hard pedal with these is notoriously annoying! So you are not alone.
