Ok so I have just done about everything in the books to try to fix my 2000 beetle brakes. So I replaced both rear calipers two rear brake lines I changed the brake booster the master cylinder. I spent 2 whole days bleeding the car from the master cylinder to each break line to pretty much anything that I could think of would have some air in it! I'm getting a pretty good shot of break fluid everywhere I bleed. But the car won't hold pressure on the brakes if I pump it 3 or 4 times it'll be normal and get good brakes but as soon as Iet go for a couple seconds it will take the pedal to the floor it's like its not holding pressure !? Any ideas I really need this car running soon please help !!!!
