How to bleed the brakes from a Spit 1500 (Tandem)

[WIMPUS]

I have a Spit 1500 with tandem master cylinder and a pwda valve ..

how do i bleed the brakes ?

i know you must do something with the pwda valve ..

I have done this ... gently.

The trick is not to let the pdwa think there is a leak. So be gentle!

It makes sense to me!

i have heard that you must remove the switch on the pdwa.. and then you put a screwdriver in it , so it can't get away and then you can bleed the brakes ..

but i don't now if it is the right way :s

I can see the attraction of clamping the pdwa - but if it wants to move it is hard to stop (yes, I have tried).
For me, it was fine so long as you let the air out gently (no stamping on the pedal!).
Have a go!
(If you have problems ... have you rebuilt the master cylinder and put the two springs in the wrong way round ... that's what I did which is why I tried to clamp the pdwa!)

Good luck

My US-spec GT6 has a tandem master cylinder and PDWA.  
As mentioned, the trick when bleeding is to be sort of soft-footed & slow.

If the PDWA does get moved & the brake light comes on, there is a section in a shop manual somewhere about "re-centralising the PDWA".
