Master cylinder cap leak

[EMDDIESEL]

On my 01' (Four wheel disc) Ram, i constantly am wiping off brake fluid from the top, right around the cap. The level has not dropped much though. I just cant figure out why it keeps happening. Anybody else have a similar problem?

Cap Leak

My master cylinder also leaks and gets filthy all around the to and sides. I clean it, tighten the cap and still it gets dirty. I wish I could find a solution. Any help out there?

Hi guys,



This is my first post, I just joined the TDR last week, but I've been reading them since I bought my truck back in February of this year. This is a great place for information about our beloved trucks.



Anyway, I have the same problem with the fluid leaking past the cap. I think this is also leading to a brake fluid contamination problem that I seem to be having.



My truck has the AC Delco (Gack!) type master cylinder, and I'm assuming yours does as well. I saw something the other night that I'm going to try. I saw in JCWhitney, back in the section where they have the chrome goodies, that there is a chrome-plated metal cover that fits onto the plastic cover. It's was intended only for dress-up, but I'm wondering if the metal cap would help to stiffen up the plastic cap and help with the sealing.



Any thoughts?

Yup, Mine 2!!!

Just went to look under the hood, it's all dirty.



Now I have something to do, will see what I can come up with!
