I recently did the hydroboost conversion on my truck it works great but I have a leak between the hydroboost unit and the master cylinder. It drips out there when my foot is on the brake. It is power steering fluid that is leaking. Is there a seal in the hydroboost that can be replaced or do I just need to buy a new hydroboost unit? It is a used hydroboost from a 1999 f450.

 

Any hydroboost guys out there?

 

I would imagine you can do some research on the web and find your answer.

 

Yes I am currently reading here on the forum. I thought I read something about you needed to use a F250 master cylinder but I can't find the thread.

 

I used the MC from the same year truck. Mid 90's F450.

Sorry, I have not had it apart yet...thankfully.
