im leaking from a brake line but that doesnt bother me as much as the fluid coming out the back of the master cylinder i put a new gasket on because that was shot but i can not get the cap to close wout the gasket going down into the fluid causing more to spill out

Are you talking about the insert in the lid of the master cylinder? OR, when you say "back of the master cylinder" do you mean where it bolts to the booster?

If it the rubber in the lid, unless you have the wrong one, it should snap on. You did push the two diaphragms back into place, didn't you?

Yip, push the rubber diaphrams sticking out up into the rubber part again.

They will push up until they are flush.

i did that and it still blows back out

Is he talking about the master cylinder lid of the very back of the master where it bolts onto the booster.
The master lid leaking is a common problem on a few years . If its the lid it need a new rubber gasket.
And make sure all 4 corners snap down or it will leak.

Sounds like the master cylinder is too full.

s10blazerman4x4 · #13 10-24-2004, 02:28 PM

but its not its actually only half filled cuz it keeps leakin out the back because the new and the old gasket under the cap kept getting pushed into the fluid which sent it out the back and im not leaking from the line which i said above i found its running down the frame rails and such onto the tranny

Mikado14 · #14 10-24-2004, 04:22 PM

Listen carefully here, If the master cylinder is only half full and the rubber gasket is pushing the fluid out the top, what's wrong here?

Read the previous posts. Have you pushed the diaphragm's of the rubber back into place? Is the resevoir still seated into the master cylinder?

Just snapping the lid on will NOT push fluid out unless you are doing it with the diaphragms extended.

Hold on a minute, you said "old and new gasket", you do have only one gasket on the lid, don't you?

Push the diaphram back up into the lid.

Push the diaphram back up into the lid.

Push the diaphram back up into the lid.

Push the diaphram back up into the lid.

Underneath the lid it should be flat with nothing sticking down into the front and rear resovoirs.

Take a better picture of what you are talking about instead of that picture which shows us nothing.
