@NarimanAsgharian I'm not sure how many liters, but we had flushed the brake lines a total of 27 times from the very beginning to end. The brake shop verified that the lines weren't the problem. They believe it was the wrong brake booster and master cylinder for my car. It is a right box wrong part kind of thing.

@NarimanAsgharian But if I had to make an extremely rough guess, I'd say it was at least 67 or so liters. We flushed and then pumped the brakes as per normal procedure. Then had the same problem again. But the brake shop said the lines and brake fluid are not the problem. It was wrong parts not fluids.

I'll keep you guys updated on this. So far the parts that are wrong are the master cylinder and Booster from what I know so far. Still getting information in on it. They have the exact same look and serial number.

Accept the part has 1 digit that is different on the part for my car. The brake booster and master cylinder on my car goes to a 2001 hyundai Accent. Only problem is mine is a 2001 hyundai accent GS hatchback. Just the name is the difference in the cars. So this is how is the dealership got the parts mixed up.

I have to give them the exact full name for make, model, year, subversion, and leading title on my car. This is how the brake shop spotted the wrong part on my car.

Made an appointment to go into hyundai dealership in early November. They'll replace the parts for free. Since their technicians got it wrong.
