Stag Stag PDWA vs TR6

Hi,

I'm fortunate enough to have just acquired a running driving '68 Triumph 2000. All the 2000 guys seem to think that the Stag brake master cylinder along with Stag calipers is a "must" upgrade....heck maybe even the Stag rear brake set up as well.

I've found a used Stag m/c (new are silly expensive) as well as rebuildable calipers. Haven't seen a lot of PDWAs for sale out there on the net, but I have lots of TR PDWAs. From reading other posts, it would seem that I don't really NEED a PDWA, but I figure, it wouldn't hurt to have something telling me my brakes are failing...aside from the pedal. That said, does anyone see any reason why I couldn't use a TR PDWA? Also, the 2000 was never wired for a PDWA. Any thoughts on wiring one up?

Oh, and if anyone happens to have a STAG rear brake set up, please drop me a line

Cheers,

Todd Bermudez
 
Congrats on the acquisition. I can't answer your question but please visit my friend Jamie's web site. He may be able to answer your question about the PDWA and other items. His 2000 estate project has slowed down quite a bit but he's probably able to answer your question.

Hi Todd :

I don't see any reason a TR6 PDWA wouldn't work with Stag brakes. Really the only difference in the PDWAs is that the Stag uses an extra connection, while the TR6 has a separate tee. Both MCs have the same bore front/rear, so the pressures are expected to be equal.

I always hate getting rid of 'spare' parts ... no matter how unlikely, I just know I'll need it if I don't have it. BUT, they are taking over; both sheds are full and there's a dashboard in the living room, so if you'd like to make an offer ...

Hooking up the warning light is simple, if you don't worry about the "bulb test" function required by US law at the time. Any old indicator bulb (or LED) will do, with one side wired to the switch on the PDWA and the other to the ignition circuit (power only when the key is on).

If you do want "bulb test", then I would suggest adding a simple 12v relay. Ground one winding and one contact, then the other winding goes to the white/red circuit (starter solenoid) and the other contact to the PDWA wire. When you crank the engine, the relay will close and light the PDWA lamp.
