Hilux booster to big for 1uz

[mick08]

Hey, anyone put a smaller brake booster on a hilux RN series, i have thge standard one that measures aprx 240mm,i know the diesel one is about 220, is there another option people have used. I have heard about the VH remote booster,whats involved with that it looks very small in comparisen to the hilux booster,can you just run an extra vacuum tank to compensate?

just find a smaller booster out of another toyota and mod the firewall + pedal box to suit (or a datto 180b booster maybe)

provided you have a master cylinder on there the same size as factory the braking capability won't be affected.

remote boosters are a pain in the arse so avoid them at all cost, a twin maso arrangement would be better suited if you want to start changing things significantly

I changed mine to a diesel booster when I did my 1uz conversion.
