VT brake conversion onto VP

[Abrowne70]

Hey guys picked up some vt front calipers, brake booster and master cylinder today pretty cheap.

Now i know for the conversion i need floating hubs, which are roughly $250 on ebay(if anyone knows where they are cheaper let me know please) but i have also read that VR/VS dont require these floating hubs because they have some of their own.

My question is, am i able to get the hubs of a VR/VS and use them for the conversion onto my vp.

Thanks

only if u use the whole wheel strut id imagine

This was discussed in another thread recently and it came to the conclusion that it could be possibly to use the whole VR/S strut with a VN/P bearing plate on top to mount it in. Know one actually tried it though, but if you can get a vr strur assembly for next to nothing then it may be worth a shot as the theory seems to work. You will still however need the egg rings($30 ebay) on the vr hub to fit the Vt rotors still.

sounds like a lot of bother to me lol = id rather pay the lil bit for the hub adapters and leave everything else alone but thats just me

[VrWagz1]

^^^I think your right, hub change sounds easier to me too. But if he has a hoist, rattle gun and cheap vr stuts then it may work out cheaper and wont take long on a hoist plus you can change a few bush's while your there.

Yup that's right, the entire strut is required to fit VR/VS hubs onto a VN/VP. They used a different style bearing and hub assembly. I'd personally stick with the VN/VP style strut and bearing assembly, only as they are user servicable bearings, and much easier to remove/regrease/replace. You also don't have the issue of rotors becoming rusted onto the bearing assembly, and requiring the assistance of a mallet to remove.

I think some fiddling needs to be done with adaptation of brake lines, double check on that mate

i just want to say you cant use the vn-vp strut tops on a vr-vs strut the vr-vs sharft is thicker then the earlier models and wont go into a vn-vp strut top

been there tried that

[Abrowne70]

yeah decided ill just fork out the cash for the adapter hubs, only couple hundred and makes it alot easier, yes i have access to all those items(hoist, rattle gun etc.) but just be neater using the adapter hubs and when i want to sell my car and keep the conversion i can.

So where apart from ebay has the adapter hubs and prices?

[v8_bomberdore]

sydney race brakes sell the hubs but they have no stock for at leased 2 weeks away and wen they do get them in u will be looking at close to $300 and that doesnt come with bearings either, also u will need the longer brake lines and there $150 for the braided ones

i was about to do the same thing i got some VT SS brakes of a mate for $250 and i should have realized how much F-ing around it would be, damm

agreed. the rotors on mine were a bitch to remove the first time

mate when you assemble thing pretend you are a diesl fitter and paint every thing before assmelbe with NEVER SEIZE.

can i take offence to that?

[MasterOfReality]

Also, if you are using adaptor hubs and you want it to be legal, an engineers is required for it

hopper stoppers is hell expensive - i can get it bought and installed for less than that in perth here

there charging $890 for smooth 300mm brakes and accessories letalone price for the slotted and dimpled

i got quoted $689 fitted with slotted

currently trying to find a supplier to do 296mm vp rotors.

Getting the Booster to bolt will be fun. This is going require you to have some handy engineering skills and welding skills. They don't match up. Marcovr can help you maybe and there are a few others that have threads covering this conversion on a few forums.

I found twobros in NZ make a firewall bracket for the VT-Z booster onto a VB-S firewall.
Some people have modified a VS booster bracket to bolt the VT booster to but it is a bit dodgey. You will also have to modify the pushrod on the VT booster by shortening it, welding up the hole for the brake pedal and creating a new hole for the brake pedal.
A better option is use a plastic VS booster which allows the VT Master cyclinder to be bolted to it with a spacer you can get from racebrakes sydney
if you have an early VP then you will need brass thread adaptors to be able to get the brake pipes to fit up. There is some bending of the pipes also required so be very careful

[VrWagz1]

^^you can use vs booster but it is a weak plastic single diaphram job. Your better off using the stronger double diaphram steel booster off the vt/z.

im about to put some vt brakes on my vp v8 and im going to have my brake lines modifiyed or i might get braided ones made up ,i just want to know how long do i need them to be cheers

[VrWagz1]

??are you making them yourself. If so im unsure exactly of the length, but the are longer than the stock ones on the vt. But if your buying them the brake shop will know what to make up and the fittings needed on the ends

[Fu Manchu]

yes but the VS booster is matched to the stepped bore master cylinder that was closer to the VT master than the VR one.

Just suggest using it to avoid to much fluffing about. Yes the VT booster is a far far better option but get the firewall bracket made to suit and engineered and the push rod modified.

im getting the vt lines with the calipers so i was just going to get them modifyed, ive been looking at some of the kits that comes with the lines and they look to be around
300mm

[VrWagz1]

the vt lines are too short but not by much, i ran them on my car for a week or so then realside on full lock they were kinking. so i went and got the proper lines made up there and then.
