I built my own for my Volvo, using an extra cap. I could see a value to a safety catch, but if your cap is screwed on straight it doesn't seem like you've got a lot more risk than when you are fast braking on the highway. I have read on the Ford Trucks sites that you can't effectively vacuum bleed brakes in newer ABS Fords, but I have not seen an explanation. The Volvo users used to advocate pressure bleeding exclusively on the newer ABS Volvos, but again without explanation as far as I recall. Summary, I have no evidence, but it seems like people prefer pressure bleeding in other forums where I've participated. Maybe that says more about me than vacuum bleeding though... ;) Best, Tim > > That's why I like vacuum bleeding.
