drums all round...worth upgrading to discs?

just after some opinions. i am working on my ht (agent orange) which currently has drums brakes all round and no booster. i have a hx van in the shed that has disc's up front. i've read that it is a relatively easy procedure putting these on the agent, but wonder if it is worth it. i would have to get the rear axle's re-drilled to suit, source some wheels etc. i am told that drum brakes do perform well but heat up and loose there effectiveness at hi-temps. she will not be driven hard, just slow and low (give the ladies plenty of time to check the goods )

If you end up putting an 8 in it, you'll need front disks for sure.
On the other hand my old man's FC had a booster on it's drum brakes and they worked VERY well.
They were very sensitive though.

thanks agro,
she has a 253 already and i have acquired a brake booster. FC sensitive? to lock up? or just very touchy?

When you touched the brakes they grabbed hard.
So they were very sensitive indeed but worked a treat.

Hope this helps
