phards Posted October 31, 2011 Share Posted October 31, 2011 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!Paul. Link to comment Share on other sites More sharing options...

So be gentle!It makes sense to me!Paul.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 :sWim Link to comment Share on other sites More sharing options...
phards Posted October 31, 2011 Share Posted October 31, 2011 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 luckPaul.

rotoflex Posted November 1, 2011 Share Posted November 1, 2011 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".
