how to test lockheed boosters

[rdssdi]

I have two Lockheed remote servo brake boosters on my +2. I have heard that they are prone to seizing. They have two pistons. How can I determine if they are free and the unit is operating properly?

The brake pedal appears harder than it should.

Thanks

Below is a page out of the Elan Workshop Manual.
If you need to disassemble the unit, here is a very useful link:

Thank you for the information.

I will test the boosters as described. I have purchased a rebuild kit. The supplier only had one kit. I will locate more if a problem is diagnosed.

Thanks.

Here's another good Lockheed brake booster rebuild site with very helpful photos...

Bob,
if all else fails try this guy. He did my Sunbeam and it came out great. He is well known for his re-builds.
He is located back east and north...........
