Out of sync replica

Hi,

I got an issue with our kafka nodes. We replaced some nodes on the 
cluster and reassigned the partitions from a new topic layout. After 
reassigning, zookeeper lists the correct broker ids, but kafka stuck 
with its older brokers in its replicas. In the example below, the leader 
is a valid node, but the other 2 replicas (170064209, 171606945) doesn't 
exist anymore and that is why ISR has only the leader.

Topic: delivery   Partition: 7    Leader: 172523739    Replicas: 
170064209,171606945,172523739    Isr: 172523739


Is there anyway to fix that? After reassigning a topic to a new layout, 
I supposed that kafka would change the other 2 dead brokers for the new 
ones. But it is not happening.
