hi has anyone seen this mode to a vl turbo front brakes http://autospeed.com/cms/A_0835/article.html i have seen on ebay that vn and vl have the same front discs i don't know if the brake calipers are the same vn-vl ? can this padding up mode be dun to the vn v6 and are thy the same? this would be a good cheep mode to vn v6 front brakes!!!!! if i do this brake pad mode do i use Holden HX Kingswood pads (part number DB1023) on vn v6 as thy do in the vl turbo mod and mod the pads to fit like they do in vl turbo mode ? can this mode be dune to vn v6 ????

| Hey Mate you'd have a bit of trouble fitting DB1023's onto a vn with out changing anything in the braking system as the recommended pad for a vn v6 is DB1085 for the front and DB1086 for the rear, maybe give a brake specialis in your area a call and run the idea by them and go from there. They should be able to give you the info and advise you're after! The mos common brake mod I know of for the VN is to upgrade to VT braking systems and the Vn is pretty crap at the best of times! You need to make sure the braking system you are changing to is going to be suitable to stop your car, he gross weight of a vn v6 sedan for example say 1300 tonne and you put vl brake system on thats designed to stop a vehicle with a gross weight of 1200 tonne you're braking quality is going to be even worse then before but say you use a VT system they're gross stopping is about 1500 tonne |
I'd gladly push my holden than drive a bloody ford! |

I know for a fact that VLs used a Girlock caliper, and VNs are PBR, but that was from the base model. I remember this because I once had to improvise with a mate's VL. As we had to drive it from Kambalda to Kalgoorlie (50km) it would not do to have metal on metal to get there. Crazy as this sounds, I managed to get a set of front pads from a wrecked HZ one tonner. It wasn't ideal, but it did stop him from doing any further damage.
As for upgrading, I would go find out what the VN Group A used for stopping power. I do know those big alloy wheels weren't just there to make it look pretty; they did serve a purpose.
Disc rotors and calipers should be a pair; it's no use having 14" disc rotors if you're using single cylinder calipers. And if you're using tiny discs, using 4 pot rotors will just wear them out faster and make them prone to fading because the discs get so hot. Study the "upgrades" they put on the VN-VS, then ask the experts "does this bolt on, or do I need to engineer it?" |

| etend to upgrade to the vt commodore+ brake booster/master cylinder and front discs and twin spot calipers. More than enough to stop a vn. |
Cheers,
Nodg. |

@Mechknight - I believe the vn's use the same girlock brakes as the vl does. The VL turbo has the same calipers and rotors as the vb - vp V8's and the Series 2 VP V6.
vb-vp are the same
vb-vp s1 6cyl 270mm
vp s2 6cyl 290mm
vb-vp v8 290mm
vl turbo 290mm
If you wanted a cheap easy upgrade that would be more than adequate for a standard V6 get a hold of some VL turbo, VP V6 series 2 or VB - VP V8 calipers and rotors which will be cheaper than the VT upgrade stated above. Although not as good as the VT upgrade but still more than enough.
As for andrewpapa's original question the standard V6 calipers are different than the VL turbo ones unless they have been changed previously so the pads you are looking at will not fit but in theory what you want to do is possible if you look around as stated -
"Now the first step in determining if your brake pads have an interchangeable cousin (after a few small backing plate mods have been performed, of course) is to toddle down to your local parts outlet and have a look through their brake pad catalogue. All you do is flick through the diagrams to see if there's a big-sweep pad with an able-to-be-adapted backing plate. Note that there are limitations to how much you should modify the new backing plate, though. Only small alterations should be made to the new backing plate and you should never have to cut into the friction material zone."
If your front calipers are finned they will be the same as the VL turbo calipers and this mod will work.
Any question buddy dont be afraid to ask.
Cheers

What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

| Finned calipers? I am uncertain to the specifications, but that sounds like what the VS V8 front calipers look like. I can't remember them all that well, but those units seem to be an improvement on the standard V6 calipers. They will at least bolt up, and if there's something specilised about them, you can always get VS struts, or parts thereof to make it fit. I've driven VS V8s new, and even without ABS, they pull up in what seems like half the distance a standard VN V6 would |

| That looks a lot like what I was thinking of, and the cross drilled and slotted discs would help just that much more |

My 2 cents worth to this discussion. Best vn brake upgrade for least cost I believe is QFM pads & after that try fitting 290mm V8 discs & V8 master cylinder/booster if you still want to change something. You will need the V8 calliper brackets if you keep the standard callipers or use the finned V8 callipers.
V8 master cylinder/booster is an option that just gives lighter pedal pressure.
VT upgrade is a lot of dollars for not much improvement for a street car imo, racing would be a different story. VT disc dia is the same only thicker & larger pad area only benefit. You will need quick fill VT master cylinder, to stop the pedal going 3/4 to the floor, and hub adaptors & hoses.
I have the V8 disc, calliper & master cylinder/booster setup with QFM pads & although it is transformed the standard v6 stopping performance, I suspect that the pads alone have made the greatest contribution. Changed booster etc was for lighter brake pedal.
Only brake factor that matters is: can your brakes lock the wheels under an emergency stop (standard vn v6 brakes & good tyres fail this test - at least mine did). If the brakes cannot lock the wheels then the pads need to be changed to something with a better co-efficient of friction (QFM pads). If the wheels lock too easily & the brakes cannot be modulated to achieve an acceptable stopping distance then you need to change to better tyres.
Making any/all of the brake parts bigger only improves the heat load capability at the expense of unsprung weight. This is useful under racing conditions or on the road for extended heavy braking without a cool-down period.
