04 Monaro VXR and 04 GTO Brake differences
Discussion
Hi all,
Been collecting parts over the last few months and bought a fair few bits and bobs which I've now started fitting.
One of these is a set of russell braided brake hoses. I got ones for my year (04) but it looks like there are differences between GTO and Monaro on that year. Original hoses have square ends on brake hoses on front, whereas the 04 russell lines have round connectors. Their GTO '05-'06 set seem to have the square connectors.
Quick check on rock auto and it does indeed look like the '04 GTO uses different calipers to my '04 vxr, and the '05-'06 caliper looks to be the same (at least with hose mounting etc, not checked size yet).
I thought that the '04 GTO was the same as the '04 Monaro VXR? Is it ok to use the round type connectors on newer calipers - although think pipes may be a little longer?
I'm finding the '04 vxr to be a bit of a mixed bag when it comes to parts.....

I believe the 04 CV8 is the closest relative to the 04 GTO. I have a set of unused Russells front hoses that'll fit VXR calipers that are surplus to requirements since fitting wortec brakes .. let me know if they're any use to you.
Thanks - it does look like that. I guess the 04 VXR is a HSV coupe, whereas the 04 GTO is as you say more a CV8. Seemed to have a lot more common parts between the models for 05-06.Do the russells hoses have the square ends? If so they would indeed be of use. What would you want for them?

They have the square end though the are missing the brackets that bolt to the chassis leg, these can be salvaged from your old hoses. Cover the postage and they're yours.
Cheers! Much appreciated. I'll send you an email with details - let me know how much postage is and how I should get it to you.I've been comparing my 04 Monaro VXR front calipers to Monaro VXR 05/06 calipers, and they do seem a bit different. A lot more ribbing on mine compared to later ones. They do look more like the '04 GTO ones, although the location where the brake hose fastens on mine is like the later ones compared to lower down on gto.
Don't know if there's any difference in piston size and whether there is any noticeable difference in performance? Wondering what refurb kit would fit...
The '04 VXR does seem to have been an odd year - a lot of parts seem unique to it? Wheel, brakes, tweaked 5.7L, fuel tank etc. Was it a bit of a proof of concept or something?
Seems to be a lot more in common on 05/06 variants, inc CV8 and GTO etc.

04 VXR = 2004 HSV GTO Coupe which uses a lot of parts from the 2004 HSV Clubsport R8 sedan. They were 285kw in the day. 330mm PBR brakes were used on a lot of the HSVs from the 1997 VT onwards up to VZ? 2006. Early on they were called the Performance option as some HSV's came out with the basic Holden stuff or super duper Harrop brakes.Don't know if there's any difference in piston size and whether there is any noticeable difference in performance?

PBR later on released an aftermarket kit which was essentially the same 330mm front and 315?mm back as the HSV parts.
Maybe measure your discs as the last VZ Monaro and I think the Pontiac had similar 320mm fronts on it.
Also make sure the width is correct as there is a 330x28mm disc that was used on the mid 90s Commodores. Aftermarket places use this disc to make up better brake-kits with the stock Commodore caliper.
They are normally not hard to get parts for and not too exy compared to the AP and Harrop stuff. Obviously they are not as good as the previously mentioned ones,
Wheels were the same as the 2004 HSV Clubsport sedan in fact they might be from the 2004 Y series HSV GTS sedan of that year. They are notoriously hard to get hold of, Fuel tank should be the same as a V2 Monaro CV8 from 2002 up to 2004 and the V2 series III.

Thanks for the history. My front brake disks are definitely the 330mm ones (using DBA4048S on the front, previous were HSV branded), same as 05/06, just calipers look physically different. They are PBR branded though. Could just be change in design but was curious whether there was any other mechanical difference.PBR later on released an aftermarket kit which was essentially the same 330mm front and 315?mm back as the HSV parts.

Differential is different ratio to others as well. Sounds more like parts from various models were put together to make the '04 vxr/HSV.
Seems sourcing from australia might be required for some parts rather than US.

Back in the day, calling the Pontiac a GTO is what confused it all, as HSV already called their version of the Monaro a GTO, and their 300kw version the GTS. Differential is different ratio to others as well. Sounds more like parts from various models were put together to make the '04 vxr/HSV.

The 2004 Pontiac GTO has the same brakes as a stock VT-VZ V8 Commodore, same as a UK 2004 V2 series III Monaro 5.7 litre non VXR version. 296mm
The 2005-2006 Pontiac has the same brakes as the 2005 VZ Monaro 320mm which I think came on the UK base 2005 VZ Monaro (Fuel tank in the back seat!)
Only the HSV cars came with 330mm. DBA4048, know that number well!! Pretty sure you can get them in the UK.
The 330mm caliper is the same as a C5 Corvette but I think it has different mounts to the upright. Technically the refurb kit from that should fit as it should be the same rubber bits and pieces. Discs, no as the offset is different, pads maybe? If you are using RockyRoad, Use a 2001 Base C5 Corvette, not sure on the Z06 version.
Differentials, the manual HSV cars had 3.73 and 3.9 on the GTS. Auto was different again.
The HSVs would go down the Holden line in South Australia and then were sent to Melbourne to be turned into a HSV. The Pontiac GTO sailed from South Australia so it only really contained parts that Holden would use if that makes sense. The good part for the Aussies was when they used parts from the US cars on the Aussie Holdens. The US, nearly always got a better specified version than Oz. ie we didn't have to raid HSV for fancy parts.
The same happened when the later Pontiac GT/GXP Sedan and the Chevrolet SS sedan were sent over there.
Most of the mechanical stuff is not to hard to get hold of, or there is plenty of aftermarket stuff out there to use.
The 2004 Ponitac GTO would be close and the one to use if you need engine stuff likewise a 2003-04 Holden Monaro or 2003/04 VYII V8 Holden Commodore (SV8/SS). 2003-04 HSV GTO if it needs fancy HSV stuff!
It is the HSV specific stuff that can be expensive, bumper bars and wheels. Anything with HSV on it really!!
im assuming you mean the banjo fitting is round on the Russell hoses where oe is square.
what matters is the size of the hole for the bolt. fitting design doesnt matter.
the bracket is part of the original hose. none removeable , I made an l shaped bracket that my braided hoses clip into .

Apologies to drag up an old thread, just been searching for Flexi brake pipe info as bought some new Proline braided flexis for my 04 vxr monaro, length of the hoses is all good, but as original poster said the new ones have a round banjo and original rubber hoses have a square fitting.
Has anyone fitted the round type on original calipers ok? Pipe kit came with new banjo bolts and copper washers. Don't want to start doing job if it's a no-go.

As maccavvy has mentioned above, it doesn't really matter, as long as the banjo bolt and hole through the brake-line is the right size. Worse comes to worse, you could use the old banjo bolt with the new copper washers. I would be testing the new banjo bolt first in the caliper.

There should be plenty of space for the round fitting as the original square fitting is so big!

There is a chap who’s on this site who can make up hel brake lines he built me a set for my 04 cv8 monaro , he’s on ebay they were not expensive but work very well
Cheers I've already got a set from proline, they had 20% off so jumped on and got a set of 6, front rear for £71 in a fetching translucent red
