I bought a car for cheap off a guy and when I bought it the car brake pedal would go to the floor every now and then while driving and only would always go to the the floor when making a uturn or turning the wheel all the way to the left. I replaced the brake master cylinder and bled all the brakes in the correct order and the brakes are fine now but still go to the floor only when making a uturn or turing the wheel all the way to the left, they start working again after I pump them twice. Could there be a problem with the brake booster? I checked and have no leaks either

 

I cant see any connection between a U-turn and braking. Have you adjusted the rear brakes?

 

I cant either thats why im wondering if anyone has encountered this problem

bumpppp

 

Damn No one ever had this problem

 

Are you losing any brake fluid? The only thing remotely connecting the steering to the brake system is your brake lines, and the only way I could imagine explaining this is your front lines are leaking during heavy turns.

 

bump still no fix to this problem
