Saga continues. ABS BAS ASR lights back on, and now staying on.

I have read nothing in the forum about brake booster replacement as solving this problem, even though that's what the latest code indicates.

Can anyone give opinion on this? I hate like h**l to replace the booster and then still have the problem...

Thanks in advance.
