Hi everyone!
Sorry for my bad english - writing from Estonia (Europe)
I have a big problem and no one in Estonia can't help me cause 2nd generation
gs300 isn't very common car.

About 9 months ago started ABS VSC aso. to shine.
So i went to local Lexus dealer and they said that brake booster is broken and there's
no way to fix it. New part costs approximately 3000 dollars.

Finally i found used part and everything was ok.
But now, it's broken again. Is there any possibility to fix it?
Especially if i have still old booster in my garage.

I have read that it's very common problem in 1998-2001 gs.

So,i hope that someone can tell me that is there possibility to fix it ( make one from two)
and what parts in this booster brakes down.

Again, sorry for my bad english and
i really hope that someone can help me.

Greetings from Estonia,
Asko

 

If you do a search, one of the guys recently replaced the motor within the unit.

This links shows the workings of the BB motor. It might be worth opening your spare and taking a look.
Good luck

 

if you do end up replacing your master cylinder/brake booster components can I buy the old broken ones from you ?
