Do check brake calipers guide pins . they are often neglected . get them checked as well
That idiot mechanic of your has forgot to bleed the system... Also if you have Kabli master cylinder it can't be trusted
For me, the issue was with ABS unit. I had also changed master cylinder but it only fixed issue for only few weeks after which it again happened. And it usually happened after ABS is triggered and then break stayed like that. The seals in ABS unit leak the pressure
Exactly , I have disabled ABS and now issue has resolved no more pedal sinking , Can you please tell me how much ABS unit cost you ? and from where you purchased ?
My passo has started doing thisand found my own reply in here
anyhow to sum up it seems like a fault in passo ABS unitwonder whats the current kabli unit rate these days
