Rumble when breaking between 60kmh and 50kmh

[CB900F2]

Hi all

In the past few months my 08 Sedan (auto) has developed a rumble through out the car while I am braking aggressively that only happens while the car is slowing down through 60kmh down to 50kmh..

I replaced my front rotors thinking that was a possible issue. and it is not a pronounced, but still happens..

There is no shake in the steering wheel, nor any feedback through the brake peddle..

Any thoughts?

Thanks all!

Forgot to ask also.. Anyone had any issues with the mounts on the Yaris?.. will be checking them out to see if there are any issues with them.. The one under the battery looks a bit tough to get a look at its condition with out having to remove the battery tray etc...
