Hey, had seized bleeder screws on my front calipers and I replaced the bleeder screws with acdelco replacements. I was trying to bleed the front brakes with a vacuum pump and I didn't notice a continuous flow. The rear wheel cylinders that were in the drums bled very well but the fronts aren't. The brake peddle I noticed is very spongy and doesn't build pressure. And I don't think I have a brake line leak.

Any ideas?

The NBS and newer need a scan tool for a full bleed. Sometimes you can do it without. Sometimes you have to use it. It's kind of hit or miss

Thanks I did order an autel ap200c tool that I guess is almost same price as an hour at a shop. I'll give it a try maybe post a review if it is requested
