Hi Guys
I'm in the process of changing the brakes on my van and at the same time I will be upgrading the master cylinder.
To make upgrading the master cylinder easier, I plan to also change the booster. The Ford XA/XB master should work well for the brakes I am using.
During my research I have found a booster that will bolt to the Bedford firewall and except the falcon booster with no mods/filing etc at all. My only concern though is the booster I have found is pretty small. Its 180mm dia.
Anyone have a clue about booster sizes and their effectiveness? The particular booster I have found is available in single and dual diaphram in the same dia.

It doesn't really matter what size you use - example; think of HQ holden (big booster) now think of titan/dyna etc truck (small under dash booster)
even compare things like escort and hq or torana and hq
The booster is a vacumm, it can only vac so much whether duel or single and the valve (pvc vavle) stops bleed back. The more important thing is master cly type/size; ideally you need to have big enough size to feed the wheel clyinders and of proper type disc/drum or disc/disc although you can use drum/drum master if you are running disc/drum setup (ie bedford booster and master with hq discs on front) with or without a proportioning valve.
Probably a better example would be hot rods, a lot of hot rods place the booster under the floor to keep a clean engine bay, they use a small truck type booster (the titan/dyna etc style) and as we know these rods can be from 100 to 1000+ horsepower running alsorts of suspension and brakes

Thats good to know. I'll try this one out and see how it goes. I'm just happy it bolts in with no mods.
-
If you don't mind me asking, what is the set up from that bolts straight in. Thanks

Once I know it works I'll be sure to share. I have a few of these boosters here to sell if they work. Much cheaper than LJ booster to.

Ok, Thanks

I'm running a commodore booster for the v6 standard van and using toyota booster for the v8 in the custom

L300 is a nother popular one for customs, it goes under the dash leaving that smooth look under the bonnet ::)
-
i like the idea of the l300 under the dash .. but wasnt sure of the size as they look small
the new shape hiace has a small setup in tghe front bonnet area .. less room than a bedford
-
a mate used the L300 on a fc holden, running a tuff 327, with 4 wheel disc's. He pulls up great. He also uses a vacum cannister, but thats due to the size of the cam in it

interested to know how you went with this ?
