I have check the vacuum pipe it is completed ok. But this brake issue happen sometime not regular.
There is no issue in the steering wheel.
I have find a problem but not yet confirm. There is a minor leakage in the throttle body. There is a sealant where the throttle body attached. It was in bad condition. I remove that sealant and contact as metal to metal seal. Now it work fine but lets have a test drive then i will update on the mentioned issue.
