I’m 20 and normally do all my own work and if I need help my dad who has been working on cars since the 60’s normally knows what to do and then I have a mechanic friend that I use as a fresh set of eyes when I need them. With all that being said none of us can figure out what is wrong with my brakes in my 1998 2dr 4x4 Tahoe. My pedal goes to the floor but once it gets there it’s like a normal pedal but the rest of the pedal travel has no resistance. I’ve replaced and adjusted rear wheel cylinders and shoes, I’ve put in a new abs module which I had bled with a scan tool multiple times, 2 new master cylinders (bench bled before install), new front pads, and a new rear brake line. With the rear jacked up on stands when I put my truck in drive and hit the brakes the rears don’t start to stop until the pedal is at the floor. And because I was curious I even adjusted them to where they were pretty difficult to get on and off and it didn’t make a difference. With all that being said I don’t hear any hissing that indicates a vaccuum leak but when the pedal is almost to the floor I can hear kinda like a groaning or creeking coming from what sounds like the booster. If anyone can help that would be awesome!
