Leading question with minimal facts and less practical knowledge:

I came back from very short Sunday drive and noticed that my 2 was marking its territory at the right rear leaking brake fluid.  I took off the wheel and drum to see if i could identify the issue and it appears that fluids are coming from the rear boot/cover.  I tested all the fitting and they were nice and tight.

Can anyone give me some vision and direction as to what I should review next?  Mind you this is on the backside of the brake plate thing.  They seem to weep until the pressure reduces and then it stops.

thanks in advance....

Not really familiar with the Lockheed brakes but the copper gaskets on the "banjo" fitting are very sensitive and will sometimes leak even though they appear tight. If that's the case it's a cheap fix.

Tom,

thanks for the quick response as this is is exactly the ideas that I am looking for.  I know where the banjo is and it did appear to be tight as I was gingerly checking so as not to over pressure it.  If I take it out to either check it or re-seat it, will I de-pressurize the entire system and have to re-bleed entirely?

thanks again....

You'll have to bleed that wheel at least. I think you're supposed to bleed them all and I think that's best but I don't always do it. Here's my shade tree diagnostic: I'd lift it up, remove that wheel and clean off any wet areas with Brakeclean or similar spray. Be sure the leakage is brake fluid; I find the odor quite distinct. You should see some loss of fluid in the master too. Then get someone to stomp on the brakes and hold pressure on the pedal for a minute or two. Repeat until you find the leak or become convinced the leak is elsewhere. If it's leaking enough to leave a spot on the ground, it shouldn't be too difficult to find.
Good time to have a look inside too. Back off on the adjuster and tap the drum free with a hammer. It usually forms a ridge on the edge that hangs up on the shoes so back it way off. Coax it over the shoes. Check for wet areas (leaks inside are usually the cylinders), glazed shoes and wear.
Very nice car by the way.

Took the drum off as you mentioned and the interior is dry as a bone and the fluid is definately remote to the other side of the disk thing and when I move the rubber boot, the fluid is in there and only when system under pressure and the leak disapates as the pressure does.

clear as mud?

Marc,
My brakes are Girling so I'm not going to be of much help with the details. Maybe some Tr2 person will chime in here. I assume you've checked the bleed screw and the line. My guess is still with the banjo. I don't think a cylinder leak would show only on the outside. I'd get a couple of sets of copper washers and take that fitting apart. If the new washers don't fix it then it might be possible to put it together without that boot so you can see what's happening.
