You don't say if it's an 88 or a 109.
88 try the above
The 88 is quite straight forward to bleed compared to the 109.
109
I had to remove the front drums, and shoes, pushed in the slave cylinders and clamped them in place the re-bleed the system. Also I have in the past pulled the back plates off, with the shoes clamped in place, tipped them upside down, so the bleed nipple is at the top and bleed them. A lot of hassle but it does work
