I have just had the master cylinder (large cap type) refurbished and relined by Pastparts of Bury St Edmunds, after having dismantled three older master cylinders and having bought the new seal kit from John. I have done a drawing covering the repair and will send you copy if it is any use. I assume that the flexible hoses are not blocked and the bleed screws are not blocked. As you are still not getting any fluid out of the front left and rear right the problems still seems to be in the master cylinder. There is a possibility that the small supply holes from the plastic reservoir to the the master cylinder have become blocked thus preventing any fluid entering the master cylinder block. When I dismantled the old ones these holes were blocked. They are very small and need to be cleaned when you dismantle and fit new seals. Peter Tyler
A bit more progress made, I rigged up a vetinary siringe with a suitable bit of tubing and pumped fluid into the bleed nipples, worked especially well on the offside front caliper, air was expelled into the reservoir and then the level started to rise. I'd say the brakes feel and react normally now, certainly the calipers so that's a result.
