hj47 brake upgrades

Ok folks
Had this sucker nearly 20years
84hj47 trayback
Fairly kitted out for touring soo on its gvm limit
Brakes have been shit for years.

Front are disks
Rear drums

Done the slotted rotors thing and maybe new pads
Slight improvement
Lifted the lpsv valve myself... more improvement
But brakes terrible

Try another 10years and finally found a decent brake shop to do r&d and fix my woes.

We used a master cylinder off a early hzj80 series as it has a larger bore.
Used a brake booster off a Toyota hilux /4runner 1991 v6 petrol vzn130r model.
This booster is bigger than the hj47 from factory.

Flush brake fluid and replaced.

4wd now stops a shit load better.
I used to go do some mad hill climbs and the old booster , you would need to put both feet on the pedal for the ute to actually stop otherwise it would just roll back ever soo add lowly which was f##kin scary at times.
Because your legs would shake from putting soo much pressure though the pedal
Vehicle estimated weight around 3.1- 3.2t.

I recently had a few loads of wood to take to tip to recycle
Including trailer i was almost over 4.2ish tonnes.
Found a hill to test new brake setup with trailer fully loaded.
Very light foot pressure and the new setup held on the hills with ease.
Noo slow creeping backwards as with old setup

Very happy customer and finally have some half decent brakes

Only mod to booster was cut the thread down soo it wasnt longer thsn the previous booster setup

Cheers :armsup:

Make sure brake hoses etc can handle the increases pressure. Always good to replace after a few years

Re: hj47 brake upgrades

By the sounds of things you've just about done everything short of a hzj75 disc brake rear end braided brake lines would honestly be my next point to go to.
hj47 ground up resto 2inch bodylift,2 inch suspension front and rear tjm Diff locks, arb bull bar,190l sub tank, turbo and intercooler set up would i do it again Yep

Re: hj47 brake upgrades

I dont need to go disc rear

It has plenty of stopping power.
Now :armsup:

Only next thing is up the size of the wheel cylinders in the rear drums
If that hasnt already been done
