VN 270mm -> 290mm Brakes

[mischa]

Went to the wreckers today and got some brakes of a S2 VP (290mm discs and calipers) and a 1" master of a V8.

Is there anything i should replace before putting any of the above on the car? Also what the best way to do it.

[immortality]

personally i woulda got a new M/C as you are then assured it will last the rest of the life of the car. otherwise the upgrade is fairly simple. just bolt on really. suggest you get some new copper washers to ensure a leak free seal when fitting brake lines to the new calipers. also make sure you pack the bearing with plenty of good grease.

new front flexible brake hose.
about $65 each.
Then if you have enough left over the rears aswell.

Ok, what about draining the brake fluid? i have to do that right? How do i do that?

Also what's the min brake thickness for these rotors?

Was there or is there a big difference in the VN and VP brakes? If the answer is yes im ripping stealing them from my donor car.

VP S2 brakes are apprently much better. dno how specifically

[padrickz88]

tell me how it goes i have a set of vr caliper's here, pretty sure all i need is the disk (would be something slotted)

[needwork2-4fillhabbit]

I didnt really feel a difference in there brakes, thats why i was hoping for a good explanation on why the VP brakes would be better. Bigger and age i guess is a good reason to swap em over anyways, and the fact ive got to pull the lsd diff off the VP anyway may as well poach the brakes.

[centy]

rear brakes are the same.
on later vp, vn fe2 and vn/vp v8's have larger diameter brake rotors and calipers to match.
the reason they are better is the pads will have more surface area to grab the disk with to stop the car.
The calipers are rib to increase cooling to reduce brake fad under high load.
With the diameter being bigger the brakes will be able to grab further out and therefore increase the leverage (distance from center) which will reduce the load on the brakes for the same stopping power.

Only down side is you may need 15 rims to fir them.
to bleed my brakes u got a empty syringe (large) and suckeed most of the fluid out of the bottle ontop.
then used a little to clean out the crap that had settles on the bottom then filled the tank up and bleed the wheels, stating with closest till the fluid was all clear. (my old fluid was blackish green and new was clear)

it's a small upgrade only. bigger rotors will dissapate more heat. both the old VN (actually going right back to VB) and VN V8/VP use the same size pads (DB1056 or DB1057 i think) and same piston diameter in the calipers. the later model calipers do have the fins for better cooling. to really makethe upgrade worthwhile oyu better off fitting some slotted rotors with some decent pads

I see what you did there. ^_^

But I have to agree with what immortality has said. It's an upgrade, but not a big one. It's not really a huge difference... until you step up to bigger calipers and bigger rotors with better pads, you're not going to be getting money's worth.

if you need new rotors anyway, and can get a set of calipers cheap(dont anyone fall into the "VL TURBO" calipers bs, theyre exactlty the same), then its a worthy upgrade, unless you're changing master cylinder aswell.

theres also one thing that everyone overlooks, it is only a slamm thing, but it contributes to bad pedal feel and some lost braking power.

the bracket at the front of the master cylinder. get someone to get in the car and push the brakes all the way, and watch the master cylinder from the side, most of the time, it will move 4-5mm. this isnt much, but at the pedal its supposed to equal about 25mm of pedal travel that you're losing.

i made one up using some 3mm aluminum, a drill, hacksaw, vice and hammer.

i did the v8 rotors, calipers, master upgrade at the same time, so cant tell you the difference it makes by itself, but overall, my brakes i find are pretty damn good now.

[immortality]

your always gonna get better pedal feel when upgrading the master cylinder to 1" even when fitting the finned calipers because all the calipers use the same size pistons (so you have effectivily increased the leverage force of the brake pedal). i also agree with upgrading the bracket that holds the M/C. i've seen what your talking about and have seen similar upgrades on other cars.

if the upgrade was free i certainly would do it, if i had to pay for parts i'd go for the VT upgrade instead

True but VT upgrade pretty expensive when you compare it to the v8 upgrade. Though rotors and pads are same price range if not a bit cheaper for VT ( calipers cost same aswell from wreckers if your lucky) the hubs and brake lines add another $400 to the conversion

[purrVN]

i bought my vn with the vt upgrade already done... brakes are absolutely brilliant by comparison! i'd go for that if you have the cash

[Brin]

purrVN, are you able to post pics or anything of how the VT conversion sits/looks?

[ibs87]

the vt conversion is only on front brakes..tru?? and r they straight bolt in o do u have to upgrade other parts of braking system??

for vn/p you need these first before the rotors will fit VT BRAKE CONVERSION HUB ADAPTORS VB VC VH VK VL VN VP - eBay Other Brakes, Brakes, Car Parts, Accessories, Cars, Bikes, Boats. (end time 13-Jan-09 09:36:58 AEDST)
Once ya got them all sorted then your on your way. You can fit the vt/z rotors calipers on the front. You still may need the adaptor brake lines aswell, not to sure for vn/p
