How do you test a brake booster???

All True Herman

I see now.

I was going with the "Pop" he heard when he applied the brake.  That would be the most logical first.  That's why I told him to look for the puddles of fluid first.

Hey JB do your brakes go to the  floor then get better as you pump the pedal? If so then it is the master cylinder.

How do you test a brake booster???
« Reply #32 on: May 06, 2008, 05:27:32 AM »

I climbed under the car last night and found all the lines and saw no leaks.  I then went to the master and took the top screw in the middle of the gold plate out.  The cap would not come off easily so I stopped and felt around it.   If feels like it's on the same way a beer bottle cap is on.  I left it till I got word from ya'll.  I'm thinking if I pop it off she's a not gonna go back on.   

So my question is should it come off easy and has just corroded together?

It 'should' come off easy once the bolt is loosened.
The gasket in between is most likely just sticky.

Give the edges a tap with a screw driver handle.  It should come off.

I figure it's better to go nice and slow to avoid making more out of a problem.
 
Now figuring the gasket's seen it's last days is this a part I can pick up at the auto store or will I need to start hunting one down here?

These gaskets are pretty durable usually, but should be hard to find or make yourself in case it tears.

That usually means the rear brakes need adjustment or there is a dot of air in the lines.
 
Jack up the front wheels and spin the tires by hand.  They shoud spin pretty free with just a bit of resistance.  You should only need one hand.  2 handed means you need to look into the calipers.  Those calipers don't get stuck in the guides as a rule.

Well they mystery is solved gang.  In order to have leaks you need fluid. 
 
I did as directed.  Took out the bolt.  Gently tapped the cap and she poped up ever so gently and easily.  The gasket was stuck so I used a sharp edge putty knife and was able to get it off with out loss.   Below is what greeted me.   So now I got to take this off and recondition.  Is this where I need PB Blaster for the rusted bolts holding it on?    What kind of project am I now looking at in terms of brake lines?  Able to clean or have to be replaced?

Wow... That's a bad case of rustysludge...!

I think you're looking at a complete brake-system overhaul here.
New mastercylinder and brakecylinders and distribution-block. You might be able to flush the brake lines when the cylinders are removed, but new ones would be better of course.

If I were you, this would be a perfect time to upgrade the brake-system to a dual (front/rear) brakesystem. (Must safer aswell if there's ever a failure in the system)

What the. . .  .
 
Good Gaud. . . That's loaded with water. 
 
Right off the bat, the fluid hole is plugged.  Looking at that, I have to say you definitely have to start with the master.
 
Hard to say what's below the master in the lines.  But looking at that, I may suggest you get it picked up by a good local shop and let him do the whole system over.  Most of the parts are readily available.  This is going to be way over your head I am sorry to say.
 
Look for a shop with a good reputation.  Stay away from the chains.  Sometimes a long time tire dealer is a safe bet too.  See if you can find someone who carries an AARP card .  In your position it's hard to know who is a BSer and who isn't.  I have an expression. . .There are mechanics and then there are MECHANICS.  The only guy I know is 2 1/2 hours from you.  But if you want, I'll ask him. . . . He has a flat bed

Sounds like I'm looking at some serious jack.  
 
I agree on finding someone I can count on.  Would your friend be able to give a cost to redo this just from what I've posted.  Maybe with some luck he'd know someone here in Ft. Myers?  If push comes to shove I'll use him.   Saddly it won't be something I can do anytime real soon if it a few grand to redo.
 
Like my grandmother use to say if you can fix it with money don't worry it'll get fixed.  It's the things money can't fix like a sick child you worry about.
 
Well now I can concentrate on the carb and getting her running smoothly for when she's got her new shoes.

I should have asked in the other post, what would have caused that and how do I prevent it from happening in the future?

That's a good question
 
Looks like someone put water in there for the lack of break fluid. . . Unless the car was submerged
