For this sort of problem i'd check two things.Hi bro, my wife myvi brake is operate abnormally. I have to pump the brake until felt the brake bit. Then, when I put my feet on the pedal for a long time, the pedal start to go floor, same as when sudden braking. The pedal will straightly went to floor.
What wrong with the brake? I've bed-in the brake before but problem still occurred.
Please advice
1. Is your oil level consistent or does it drop? If drop means you have a leak in your system somewhere.
If not it's probably time to bleed the air out of the system.
2. How old is your brake hoses? If old and cracking you should change them. What mods have you done to the brakes? Did you change the servo?
All really depends on the condition of the above.
I just remembered something. Did you take out the calipers like I have? Did you ensure left and right positions are correctly installed? Make sure the bleed nipple valve is facing upwards not downwards. If downwards the problem is with your caliper install - it's reversed
