master cylinder

[Ran Hanks]

I decided to save the 100 bucks and replace the master cylinder myself. I have done very well until I got to the two hoses that connect the reservoir under the hood to the master cylinder. There are hose clamps underneath reservoir, Are those the ones I undo?

I am so frustrated I am resorting to brute strength to get them off. (I am not the strong so nothing can get broken, which frustrates me even more but that is another post).

Are they supposed to slip off the top of the master cylinder?
Can I just cut them off and replace those hose?
What size are they? Anything special about them?

thanx

Hi Ran,

Let me start by saying that I am a rookie myself, but I did put in a new Master Cylinder a couple weeks ago in my '67 912. Since nobody else has replied to you, I'll give it a try. The gasket on the old one was pretty much shot on mine so the feeder hose from the reservoir was just loose. I found that the metal end of the feeder hose has a lip on it that popped pretty securely into the top of the new master cylinder. There are no leaks so I'm tempted to believe that's all there is to it.

Now, having said that, remember that these beauties have a single circuit brake system so if that hose comes loose, there go all your brakes save for the emergency.

If someone else can either confirm or correct this, you might save both our skins!

The lines that run from the reservoir to the master cylinder are flared at the end, and sit under a rubber grommet. Try pulling out the grommet with a small set of needle nose pliers. The hoses should them come out without problem. Make sure your new master cylinder has those grommets before you trash the old ones.
