My guess is your hilux mates cant even read !! Sounds like way too much pub talk !! Doesnt take much intelligence to drive a hilux !!

"Just out of curiosity does the clutch have its own master cylinder ? if so where does it sit. i cant seem to find it anywhere." Yes there is, its next to the brake booster.

Yeah i think your right on the money there layback i havent found the official Australian standard but Wiki and FMCSA agree with you. Hilux drivers...dont know anything

jusr regarding wheel cylinders how do you determine their size. a lot of places refer to bore size. so tonight i pulled one of the origional wheel cylinders apart and measures one of the pistons that was inside. its diameter was approx 20.6 mm and had 13/16 stamped ontop of it. would this be the correct measurement for wheel cylinders ?

Thats interesting ! Mine had 3/4 stamped on them. If you fit 3/4" ones it will reduce the bias to the back just a little.
What year is yours? There maybe a change on the later ones.

If you are in that far, you may as well just lightly hone the bores & put new cups in or if you wish to replace them ~ use 3/4" cylinders. It will improve the bias.
