hey guys, i dont know if this has been posted before but i was just curious as to why people up grade the breaking systems and rotors and pads etc.

Im just curious as to i wanna update my rotors, should i get vt ones or something?? im not sure but i know most people who do up vl's, vk's and vn's etc, all the older models tend to put vt breaks on it for some reason...

can any one help, if this has been posted before im sorry and just give me the link and i'll read it off there...

cheers guys, Todd

The biggest gain with the Vt Vx brake upgrade is they are twin piston calipers and work very well. A drawback is if you have a 15/16" master cylinder the pedal will go down about 25% before a response is felt, if it's a 7/8" it would be even worse, they recommend to use a 1" (25.4mm) master cylinder.
Now if you go 1 step further and use a brake booster and master cylinder from a Vt or Vx they have a 25.4mm master cylinder and a secondary 31mm rapid fill bore, also the brake booster has an effective leverage of 4.25:1 and double diaphram compared to Vr or Vs single diaphram at 3:1.
So what you end up with are brakes that stop with next to no effort and no pedal travel. Yes it can be fitted to a Vn, that's where I got some ideas to fit them to my Vr, check out this web site in the Mods section http://users.bigpond.net.au/jimbo123/VN/ although with your Vn I think you have to change the front hubs.

Surely you have noticed that VN's dont break for ****? If I had the money I would be doing the upgrade... VN brakes are horrible and spongey. A VT Brake upgrade with a larger master cylinder and hub adaptors would be all you want but if you really wanted performance upgrades you can go for the VN Group A brakes and other performance setups but they are quite expensive...

you can fit corvette calipers on the VNs and they are 4 spot. expensive though. PBR do a kit for about $3.5k from memory.

for a cheap performance upgrage go - braided brake lines, pbr slotted rotors and so ultimate bendix pads.


For Ultra peformance go the vt setup, brembro brakes

thanx for all the feed back, thanx for the link "jc58nc" thats been heaps of help and thanx for ur information.

hey Vn2nV yeah well when i had my 15's on the brakes felt that they were running fine, and all...on the odd occasion itd seem weird, but now with my 17's on i can tell a difference is there and basically i wanna rid that difference...

so now my next question would be, the VT or the VX ones?? what do i upgrade to...money isnt too much of an issue as i can get a lot of parts through work with discount...

thanx once again everyone

cheers, Todd
