More Braking Power

Hey all

This thread isn't a problem more of just a question.

Basically, I've just put a 200tdi out of a Disco into my Defender and from what I know it is a bit fresher. The first thing I noticed is that the brakes are much better, which I can only assume is the vacuum pump. As I said this is not a problem, it's awesome I know the vacuum pump on the Defender to be a vane type pump, and the Disco one to be a helical gear type. Is the helical gear type more efficient/powerful in producing vacuum in order for the brakes to work better (because the disco's are heavier I'm guessing) or could it have just been a problem with my old pump? There are no tell tales on my old engine, but it's just got me wondering

Any ideas would be appreciated

Cheers

Mine improved when I swapped my engine too. I thought the pumps were the same so assumed my old one was more worn..

there the same vane pump

Not trying to correct you James, but I explained wrong the current disco pump has a helical gear as the drive method, whereas my old defender lump had this type (Attached image) My bad, poorly explained
