Audi Q7 2007 3.0TDI Brake Padle sinking to floor
Hi Gurus,
I have a Q7 2007 3.0TDI UK import in New Zealand. My car brake padle sinks to the floor after driving around 120km. Happened twice, If i keep driving another 200km the brake doesn't workand Paddle goes all the way to floor.
Took it to mechanic , No Oil leak, Master cylinder replaced with second hand one, Brake servo tested and OK. No hot disc after padle sink , Brake pad are in good condition, Can't see any piston seize from outside. what the hack ...
I have only noticed the rear discs are bit low and may need replacement but that shouldn't let Brake padle to sink to the floor after 2 hour drive ?
Paddle comes back to normal after normal bleeding procedure and stay fine if I drive this car locally or don't go too far more than 100km.
Can someone please help !
Regards,
Ankit
