[Vwdiesel] Brakes?

[Joe]

Thanks for all the replies.. Lucky for me it's not my only ride, so I'll dig
into it this weekend.  And I'll keep my eyes open for one of those vane type
pumps.

Does your vacuum pump have a spaceship on the side,[a diaphragm type] or is 
it a small felow with a pipe coming out of the top of  the lid?[Vane type. 
If the latter, then check your sump oil level. This can suffer if low. 
Almost indistructible otherwise.

 Older style can have a split diaphragm.

Also look for leak in pipe to booster
