leaking hydroboost

[buickpower]

My hydroboost system is leaking between the master cylinder and the booster section. I was looking through the manual and it says that the cause is probably a bad seal on the power piston. Are the seals/gaskets available as part of a kit or do i have to replace the booster section or master cylinder or?? Anyones experience/advice in regards to this is greatly appreciated.

Yes there is a kit you can replace the seals. If you are getting backflow through the system then it is internal leakage. I will have to look and see what the part number is on the box. Real easy to fix.

Very good, and thank you. How do I determine if there is backflow through the system?
