Wondering if anybody has fitted bigger and better brakes to there truck, something like ALCON, willwood or brembro or any other brand.

I no you can fit the 4.8l brakes and some braided lines, but would like to no if anybody has gone the next step and a rough idea on a price for the whole setup. had a quick look through the search but couldnt find anything

What have you done to your truck to make it so hard to pull up? I recently machined my rotors at work, and replaced all of my pads, bleed the lines and re-filled fluids, and my 2.8 feels better on the brakes than a vz zz commonwhore that i drove today.

Im using DBA slotted rotors and Nissan pads all round and it has made a big improvement.

How much do you have to spend?

Just changing to 4.8 rotors would be a big and expensive job as I think you might have to change the whole diff housing to get the right front swivel hub, callipers master cylinder and such. I don't think they bolt straight on (but could be wrong).

For Brembo and other up grades have a look at some of the Middle East web sites they do crazy things with Patrols so you might get some ideas.

nothing much just yet, but im building up a spare set of diffs to change over, lockers, braced, 4.6's maybe some better axles depending on money and i thought while i was at it maybee some bigger better brakes if they wont heaps expensive, don't really want to spend more then 2k on the brakes if i can.

i will be putting a ls3 in with a few tweeks so i wouldn't mind some better stopping power.

the 4.8 brakes are the other option, i think slotted rotors from dba are somewhere round 400 and then whatever the front calipers cost from a wreckers maybe 300 or so, they just bolt up from what ive read so that is the most simple solution but i wondered if anybody had gotten anything more substantial fitted for brakes. i remember reading somewhere that somebody put some big arse brakes on there truck but can't find the post anywhere

I looked at brembo's for my XR a few years back. Was looking at $5000-6000 back then. They are not cheap by any means. Hardly worth it unless your planning on doing track days in the patrol I would think.

I looked into this a while ago without much success. Renewing / servicing your existing brake system or upgrading to the 4.8 calipers & rotors are your only real economical options.

I ended up deciding on replacing all 4 rotors with DBA slotted, fitting s.steel braided lines allround, sand bleast / honing / service calipers, flush and refill with DOT 5 fluid and fitting H/D Bendix pads. drive in / drive out cost was quoted at $2000 even. Have booked in for next month...

You can use a smaller bore master cylinder to increase line pressure. If you do this along with braided brake lines it should pull real well. Rotors and pads stay the same.

yeah that seems to be the general consensus among the masses, upgrade to the 4.8l brakes or fork out 6-7k for some raceing car brakes hahaha

i don't doubt they are a massive improvment over the peices of shyt that i have at the moment, i might have a look into the whole setup you just mentioned. what was the price to rebuild the calipers ?? and did you have to upgrade the brake booster aswell ??

Master cylinder sits under your bonnet. The metal contraption with the brake lines attached.



Don't quote me but I think they go from an inch down to 3/4 piston size.

I believe you replace the mastercylinder, everything else stays factory. Call up 'Marks adaptors' they do this over changing pads and rotors etc. I believe the master is an off the shelf item from another model.... just not sure which one.

I agree with what people have said, its a 4wd not a track car. An alcon or AP setup would cost more than the car. The brembo's I have on the evo might fit but why would you bother. They are not cheap. A good set of pads and braided lines is all you need. I'm not sure if they are made for the patrol calipers, bu ferodo DS2500 are a good street pad for most performance cars and would probably work ok for the patrol. Also look at stuff from endles and hawk.

If you just want better pulling up potential then pads are it. Going down long steep hills with a heavy load (often) then start playing with rotors and fluid etc.

^^ that an insane setup. That more than what used on v8 supercars and porsche cup cars doing multiple laps at 300km/h. That setup in brembo or AP would be a solid $25000. Perhaps 'slightly' overkill...?

that is a freaking awsome setup, i was think 6pot front and maybe 4pot rear would be sweet but those brakes look like they would pull up a semi with ease hahaha what brand are they ?? the only problem i can see will be the extra cost for rubber there bad enough on 16" let alone 19". buy the way hows your twin turbo ls1 going ?? im looking at doing a ls3 conversion mid year, just with out the 2 snails hanging off it :), are you happy with the result ? what kind of power are you makeing at the wheels

i totaly agree mate it's not a race car nor do i want it to be one, but with a ls3 going in im going to be tempted to give it a bit every now and then, and i would like it to pull up pretty quickly if i have to, not to mention if ive got 37's on there is a **** load of weight there to try and slow down, nothing like a sedan or hatch back were the wheels only way 10kg or so.

on a side note, i saw a brand new set of brembos for a HSV for sale for 5k so there not that expensive really.

its not hard at all to graft better calipers off any car/truck onto your patrol axels. you just need to find one that will accomodate the rotor thickness off patrol disc's (dba slotteds with something like front calipers off r33 skyline 4pots/commodore harrops or brembos etc.) something 4pot should suffice. i run braided lines dba slotted rotors dot5 fluid and bendix extreme 4x4 pads and they work good with my beadlocks and 37's. 4.8 patrols only have larger rear rotors fronts are same as any othere patrol.. just somthing to consider anyways..
