Final adjustment of 7745 brakes

Hi,

Well after putting it off for as long as possible I have finally replaced both master and slave brake cylinders on my 7745.
Up to that point I had 25% brake on the left and zero on the right.
I have adjusted to nuts at the back and now I have 100% brake where I had 25% before and I have say only 60 / 70 percent where I had zero before.
I have driven it for a week or ten ten days using the poor brake as much as possible hoping it would come to life a bit more.
No joy however.
Any ideas on how to get around the problem.

Thanks

Its probably got oil on the disc nearest the gearbox.
Only fix is to take off the reduction box and see what is wrong.
Sorry to be so negative

Can you adjust the bolt on the side with less brake to compensate for uneven brake wear.
