Its hard to tell can be many things loose pads bearing part or the control arm .

Can malfunction of cylinder cause this king of problem

Thegamemhb

Can be the cylinder but are your breaks feeling soft or is there any leak around it best thing is to jack up your car and inspect sometimes bad shocks can make sounds but not knocking sound i hope its a loose pad

sedx911

Initially it feels soft after the sound it’s normal

Thegamemhb

By intially you mean when you apply break while drivings its mushy or slow in response ? Try looking fot leaks in break fluid or around the cylinder

sedx911

No leak around cylinder
only when I apply initial force at the paddle I can hear knocking sound, when paddle 1/4 pressed no sound and everything is fine.

The sound from from front side

Sound to me loose pads then if you have ruled out that its not the shocks

Any recent incident that lead to the knocking sound ? Can you give details how did it started
