Outer Limits 4x4 Board

Im in the process of restoring a 1978 FJ40. (drums all round) and wanting to convert the front end to discs. I've come across from a later model 40, swivel hubs / discs. After speaking to two brake specialists, they both advised me from against doing the conversion, as theve both seen the LWB and tray back 40's have massive rear brake lock up probs after this conversion. Obsviously Id have to upgrade the booster as well... Any one hear any stories about the same or know of solutions? (legal ones?) cheers

i don't know about the conversion dramas there talking about,
but i can help you out here buy these , there locked as well

I ran that set up with 60 series disk and knuckles on the front and never had any dramas.

I have mostly 60 brake bits in the front of mine and its sweet, i think it depends on how they are setup.
but im happy, it makes it safe-ish to drive on road.

I have done the conversion to a 78' FJ45 tray back. It will lock up on heavy brake applications but so do alot of other utes. At least it will pull up straight, with drums allround it was a new adventure in braking every time you hit the brake pedal especially after driving through mud. Adjust your driving style & remember it's a 4B not a racecar & if that fails fit a bigger bullbar

Mine came out with disk brake fronts and shit i go through brake pads!
replaced front and back last november and the backs are fine but the front ones chew em up..... but still when you drop the anchor it pulls up HEAPS better than front drums..

Change the brake Master cylinder to a 60s

I think you will find that will change the bias going to front and back and it will pull up like a dream.

It fixed mine.

EDIT: and yes it is just a bolt on procedure.

60s for front discs and rear drums,

80s for discs all round.
