So I'm really banking that the shop didn't know about the LSPV (still haven't look it up myself) and just bleed them wrong.
Definitely bleed brakes, cost nothing, but don't expect to do it in five minutes.
Do a search, bleeding brakes on an 80 is a bit tricky because of the LSPV
Yep, still, same as above. Only cost you a few bucks, and a little bit of time. At least you can be certain before shelling out more cash
