Do you happen to have an ABS MKII-unit? With the small high-pressure-reservoir next to the almost triangular brake fluid reservoir?
If so, the bleeding procedure for these is kinda different.
Read it up in the original Volvo repair manual if you have access to these. If not, please consider going to a Volvo specialist or someone who knows old E34 BMWs (they used the same system!).
That pressure reservoir operates at over 100bar, so please bu effing careful around that, high-pressure streams of brake fluid are not something you want in your eye!
