they may as well been yesterday when i had to stop from 110km\h to 0 in a short amount of space and nearly went up the back of a falcon.
i was basically standing on the brake pedal with both feet and it refused to slow down properly or even lockup, the only wheel to lock up was the rear passenger side when i had to move evasively.
i know that the front rotors are close to their minimum depth the pads still have a decent amount left, but would to cause a failure of the entire braking system? it felt like the brakes faded immediately.
my guess is it has **** pads on the front, are they supposed to cover 100% of the rotor or like 95% in my case, there is a gap of about 2-3mm between the top of the rotor and the top of the pad.
You can see because the rotor worn enough to see bare metal where the pads are touching and at the top where its a rust colour.
thanks

time 2 get ur rotors machined wen was last time u did em lol

The pad contact area on the rotor is normal. Check your booster, was the pedal really hard or was it that you just had no stopping power? New rotors and pads will make a world of difference if the booster and vacuum is OK.
A set of slotted rotors are only about $600, and make a world of difference over standard.
Braking is one area of your car you shouldn't spend less on.

Or ask GSL Rallysport about some QFM pads, new rotors and brake flush & bleed. And ensure the pistons in the calipers are moving freely
be happy only one rear wheel locked up, if both had it would probably have swapped ends on and you woulda been ****ed then
thats a nice price, how do they compare to DBA? for that price why would anybody ever put standard rotors on their car again.
definitly throw those pads away. check booster (put foot on brake and start car, if the pedal sinks a bit it should be fine). is there air in the brake lines? (spongy pedal)

Vn brakes are terrible, when i got mine i thought 'wtf these are soo bad' then when i got it serviced few days later realised the car had no brake pads and i was driving metal/metal for 5 days, after getting pads they are still crap as. probably the worst in any car ive driven
DBA are riding the wave of a monopoly, but it has already crested and is about to break on the beach. RDA have been around since 1987 and are a quality product. They have recently gone into the performance side of brakes, which has only really been covered by the larger companies such as DBA.
Look into a different set of calipers while your getting it fixed. Go the finned ones at least.

the vn ss has 290mm discs and the 6 cylinders only had 270mm not much difference but it does help with stopping

cheers, i think ill go for the slotted rotors with police spec pads
I dunno if being able to lock it up is necessarily a sign of good braking.
VN V6 brakes atleast are shocking, go for a drive in a VS and feel the difference. Its not massive, but the VN brakes are on the appalling side. I didnt notice any gain in braking from going from my old VL with drum rears to the VN with discs all round. 330mm fronts and 315mm rears would quickly fix that though![]()
I've said this 100 times allready but all VN/P V8 brakes and VP series 2-VS are just as good as VT brakes. If they aren't then your's are worn out/stuffed. VN V6 brakes on the other hand are spongy and dodgy
now thats strange, VN brakes aren't great but mine has a very firm pedal and stops reasonably well (with decent wheels that is) on the other hand i find the brake pedal has a lot of travel on the VS and doesn't stop that much better then the VN really
i also ran the 290mm V8 brakes on my VH with decent pads and they survive a couple of big stops but thats about it really before you start to suffer from brake fade fast
another thing that really effects the way your brakes work is the shocks, ifthe front shocks are stuffed your braking is also going to suffer

But do you mean VT brakes on a VT that weighs an extra few hundred kg's or VT brakes on a VN? I think when it comes down to it, the difference is minimal between VN V8 and VT because imo half the problem is the 15/16" master cylinder. Just a 1" master and some slotted fronts and rears will make a world of difference.
funnily enough, many people have complained that the VS has a long pedal
could possibly be, i just changed the brake fluid but didn't find anything, i know one of the rear calipers is sticking a little but it sticks on rather then off unless the M/C is buggered. all i know is that the pedal in the VN is firmer then the VS and always has been.
the fact that the VN is a manual could also make a difference, engine braking works much better with a manual car

Mate, sorry to have to say this but your brakes are stuffed. To have allowed them to reach such condition is a prime example of poor (POOR) maintennance (lack of maintennance). You obviously don't know how to maintain a vehicle and in the interests of road safety you should either undergo a course or let someone else (qualified) do it for you before some poor innocent person is killed. If brakes are made of wood then your brain is filled with sawdust.
its easy to pass judgment over the internet, i have known about this problem for abit, to say i know nothing about cars is an understatement, im quite capable of maintaining a vehicle.
the reason im asking here is to see if there is anything that i have may overlooked.
so keep your comments to yourself, no one around here has the time to listen to put downs, we're all still learning at some degree and will continue to do so.
another posibility is that you have glazed the pads in a previous "hard braking" moment and pads haven't recovered. basically throw pads away at the very minimum.
i remember a few years ago places like pitstop and midas offered "free brakepads for life" if you got your brakes serviced by them, these are the type of offers i qualify as dangerous because the pads used are probably the lowest quality on the market
