Triumph TR6 - Arrgh! What Demons...

...read this board??

All I did was ask if anyone knew why silicone brake fluid would go from colored (ok, purple) to clear. Then the clutch pedal started to have an odd feel when being depressed, and dark grey/black fluid was found in the master cyl. The system was flushed, but wouldn't bleed well, so I rebuilt it (slave is only a year old).

Now the front wheel brake resevoir is empty - Christening that new servo, I guess! At least the silicone fluid shouldn't eat up anything.

Brent, Can you IR any of the leak as to where it is coming from? I had a similar problem and maybe I can help. I was able to cure it by replacing a small (pencil eraser) size rubber washer inside my pdwa. Let me know if you can tell.

Brent,

Interesting. I didn't know Lucas did hydraulics!

Well Don H, it just so happens that Girling is indeed a part of the Lucas Industries family. On the other hand, the only connection between Lockheed (the aircraft company) and Lockheed (the hydraulic company) is that one of the brothers that started Lockheed (the aircraft company) returned to the UK when he and his brother got out of the airplane business and started up Lockheed (the hydraulic company).

The two brothers actually wound up using a phonetic spelling of their last name for the companies. Loughheed, much like Urqhardt (pronounced "urk-ett"), suffers somewhat in the translation from Celtic to English.

Well, it was indeed leaking out the rear end (I HATE when that happens..). But no fluid was in the servo according to the scientific method of taking it off and shaking it. There was also still a vacuum in the servo "motor" after a week of sitting - Partco seems to do good work. All the fluid ran down the firewall.

BTW - when I pulled the old servo 3 weeks or so ago, it sloshed when shaken. Had to drain that thing really well before shipping it back as a core.

The good news about this is I found my best screwdriver that went missing 3 months ago. It was down below the clutch M.C. and behind the wiring harness. Almost didn't see it with a light right on it. Stole one back from the demon...

Sprayed down the garage with a good dose of Demon Be Gone, and put that rebuilt brake MS in. Brakes are now braking better than ever.

I've got to admit that there was more "goo" around the seals than I had expected. Had to hit the main seal area with a wire wheel to get the crud out, then polished everything up well with "Mother's" to get things smooth. Even filled in 2 big corroded areas at the end with Devon SS epoxy, and honed it down. After 2 idle weeks the test drive at 85 deg F (30 C) was nice!

Brent--Where did you get the rebuilt servo? Comments?

Rick,

Look at

http://www.partcoautomotive.com

That's the place referenced in the Buckeye tech article. You'll have to call them. They've worked with TR's before, so there is no problem. I got a rebuilt unit in 3 days, glossy black, and sent the old core back. Good folks.

As far as a difference, in my case it's not drastic. The old unit must have had a 1/2 pint of rusty fluid in it, and the plastic hose fitting was really loose after 30 years, but it apparently worked ok. But given the age of the thing it had to be worn, so time for a swap-out. Kinda like the harmonic balancer rebuild.
