Got fed up with the weepage through the rubber hoses so took everything apart.
Used 2 Girling cannisters (7 oz for brakes and 5 oz for clutch). Opened the holes in original cover plate, used "O" rings top and bottom of the plate and "The Right Stuff" to glue/seal the cannisters and "O" rings to the plate (I called manufacturer of "The Right Stuff" and they said it would be a good adhesive and sealant against any brake fluid drips). The "Right Stuff" is teriffic...the cannisters are really locked in place) Wrapped friction tape around the cannisters and the original brackets after reforming them to match the Girlings profiles and then used the original hose clamps as a final precaution against rotation.
Running braided AN4 PTFE lines and AN4 fittings eliminating the SPF fragile hard line to rubber hose assy (used from the brake masters) routing directly to the masters.
I'll post some pics if anyone interested once I complete the plumbing.
Unless you used hose that was specifically formulated for brake fluid, you will have weeping, as regular fuel hose, etc is not an effective barrier to brake fluid.
Pegasys and others sell hose that is rated for brake fluid.
Nice! What fittings at cans and cylinders did it take to transition to AN?
I know that the hose on my car is labelled but unfortunately (smirk) I put that part back together and so can't see the markings. Are your discards still around so you can tell what the original hose was? I ask because I'd like to know the answer to the issue Will raises. Mine are not weeping (yet).....
Alan, I'll get the PN's of fittings and hose. As I recall hose was Goodrich (think I still have in the trash bin)
Will, Took a few yrs to begin "weeping" but, I'm sure the PTFE teflon AN4 brake lines I'm using won't. Special hose I upgraded my SPF Cobra was supposed to not weep but, it wept too. I'm done with rubber on brake lines from now on as well as metal resivoirs.
SPF uses (at least on mine) Good Year "Ultra Grip" 3055 1/4" (6.4mm)

I went up and down on the sizes of the o-rings at the top cap neck and finally wrapped the ring base with tefflon tape to stop the seapage there. I double clamped the hose ends. The cap area has been dry for 4 years now. The hoses are showing slight weapage again, after 4 years.( SPF Daytona Coupe)
Remember that brake fluid has the property to make rubber "swell" to keep wheel cylinder/caliper seals tight. That same property will allow it to swell hose and open the pores. Flexible brake lines have an inert lining that bulk hose will not have. I would suggest using flexible brake line in lieu of bulk hose. If you can't adapt the fittings, cut them off and use a threaded nipple and clamp.
I don't recall ever seeing a brake flex line "weep" or "sweat" brake fluid.

Did you use Buna N or Fluoroelastomer 'O' rings? Nice job. Sounds like a nice winter project, however since our chassis are only 1 number apart...
I think the 'R' cars have the cans on the rear bulkhead for easy service.

See above post for pics of new Girling canisters assembled into modified original cover plate.
Pics attached of:
Drip tray with drain tube to collect any leakage from master cylinders and drain through the pan rather than collect (note pedal assembly pulled to rear for installation). Note new 7/16 to AN4 adapters installed on masters.
Layout of AN4 fittings that will connect the new Girling canisters to the masters (hose assembly and install tomorrow).
AN4 braided lines completed and covered in 1/2 shrink tube to prevent chafing of paint and other braided lines.
Pics of hose and fittings flat on floor and various shots of assembly.
Note pic of canister cover raised showing extra hose dressed to allow cover to be raised for inspection.
Hoses go through bulkhead mating AN females via a male to male adapter for the clutch and AN female to AN T with female on the run via another male to male adapter then to the masters as shown.
Hose dims follow (dims are exposed braided line, not including fittings):
Clutch canister to bulkhead 35" AN 90 each end and a male/male adapter at bulkhead
Brake canister to bulkhead 30 1/2" AN 90 each end and a male/male adapter at bulkhead and to female on the run of the T
Clutch line interior bulkhead to clutch MC 9" AN90 each end
Brake line interior bulkhead to center brake MC 9" AN straight each end ties to the male on the foot of the T
Brake line interior bulkhead to right brake MC 8" AN straight to the MC and AN90 to the male arm of the T
Canisters from Pegasus: Girling's as shown in their catalog and assembled as describen in earlier post above.
What are the fittings at the cylinders? At the ends of your hoses it looks like you adapt from AN4 to one of the (various) hydraulic flare fittings, so I'm wondering what that is, and is it the same as up at the original girling cans?
Also you gotta quit showing me that blue painted chassis. It just gets me wondering how much work it would be to paint mine that color...:thumbsup:
