Following the issue of the rear brakes locking raised in an unconnected topic l do find when braking from high speed for a slow corner on track that my rears do lockup which hasn't caused a problem but is not good as it's a sure way of spinning if it were wet and possibly in the dry. I would prefer to see an adjustable bias , l know the factory are expermenting with a valve to give more bias to the front and improve the brake pedal feel which is poor.

From comments that were made at the Autocar 0-100-0 I believe that the factory are modifying the system to adjust the brake balance to stop the rears locking.

The pedal feel on the R is much improved from the over-servo'd feel of previous 2.5l cars.

An adjustable bias would allow people to move the brake force around the axles however it is just as simple to get it right initially like an other manufacturer. Then you don't have novice drivers in the hedge.

Did you manage to get the rears locked in your "few drives"???

What is your regular chariot you use as comparison..
maybe i am just missimg something here,was it a sarcastic response and you are a test driver or something?????

I often feel a little disappointed when posts arrive about cars i am interested in and the poster has an empty profile.It just adds credibility to comments,if you see a capable car is owned to back them up.

Doesn't matter who I am or what I drive. I've given you the facts from my experiences.

I just thought the objective feedback would be valuable rather than those with either commercial interests or owners with rose tinted specs who can justify anything and everything.

£50K is a lot of money and you can only spend it once.

Fine,,,don't care who you are mate,,,but i could write anything i like about any car...I just have less respect and interest for any opinion you write on a car,if i have no clue what you base your comparisons on...enjoy the forums.

Fair enough - I'm not writing for some personal publicity.

I could give you a huge list of cars I've driven but what would that prove?

You know what you are talking about, and can make valid comparisons on cars???

For all we know you could be a 15 yr old kid who spends a lot of time reading car magazines. You probably aren't, but you have to see where we are coming from with this. I would certainly place a lot more credibility on the opinions of, say, a formula 1 test driver versus my mate down the pub who watches Top Gear every weekend and drives a Polo.

Looking at his previous post's it would appear the only
thing he owns is a motorbike. It would appear he also rides it very quickly.

Perhaps he's become so well informed by looking at all those cars on other people's drive ways when he's
delivering their pizza!!!!

Blah, blah, yeah I'm just a newbie and knows nothing about driving.

It would be very satisfying to tell you who I am BUT it would be an easy shot to take.

I've told you the situation - its for you to believe it or not.

For more information on the braking system why don't you speak with the factory. Goodnight.

Did you say newbie or anchovy they sound the same

Should we start a new thread about the braking characteristics of the Honda C90 with a top box loaded
with 3 extra large double pepperoni's. I bet you can really lock the rear wheel on those baby's. Best not
that might be an "EASY SHOT"

Have you though about changing your screen name to
"Domino"

... I must say that I agree with the earlier posters, that we'll take comments more seriously if we know some ownership history/job/whatever of the poster! Having said that its up to P290KVP to play Secret Squirrell with us (that's showing my age, eh!) if he feels that he must! :-)

Hi everyone,

A real Newby here from across the pond
Getting ready to place a deposit for a 3R over here with 1g racing.

Can't help but throw in my 2c on this topic.
1g has put about 5k HARD track miles on their M12 demonstrator and have nothing but great things to say about the brakes...I have not driven yet myself but they seem very serious in their appaisal of the car. Interestingly the other day Dean made the comment that if anything he thought it could use a little MORE rear brake bias...this may be a case of different strokes for different folks...but also alot of other factors besides bias goes into lock up situations ie, pads, pad wear, brake temp, tire, tire temp, track surface,track temp, corner camber, braking point...etc etc and above all who is on the pedal particularly on a car with no ABS or traction computer.

I am sure most of you know all this but I thought it needed to be said!

Cheers all...

jim

p.s. thanks for the great sites joust and gto3!

JCO - welcome, and thanks for the kind words about my site.

Here is my actual experience.

I've never actually managed to get the rears locked apart from on a track braking from 120+mph when I overcooked a fast sharp corner that would normal be done around 50-60mph,, so I had to take off a lot of speed .

There was no drama, but upon chatting to Lee at the last track day he recognised that for those sort of sitations on track use certain drivers would benefit from more front bias on the standard setup.

Even when I did lock them up there was no drama, the feedback from both the chassis "through the bum" and the pedal gave me ample opportunity to back off slightly on the brakes using normal cadence techniques and I still managed to get it through the corner - at about 10mph than was probably sane but it still made it (although the bum was twitching rather)

For me, doing 120+ on public roads with a sharp left is just plain suisidal, and so for road use I can't imagine that the standard setup that generates around 1.4G of deacceleration would ever generate rear wheel lock up. Certainly of the 200+ owners, of which over 30 are on the various forums, no-one has ever reported a rear wheel lockup on the road - take from that what you feel.

I've done over 10,000 of hard driving miles and the current setup is sweet, but as people know and can see from my website I'm slowing changing the car to be more track orientated.

However, those changes have their own problems as it starts to compromise the road behaviour (the difference in the low 2000-2500 rpm of the upgraded engine is just one of the problems that means the better top end you get for track use affects it's "pootlability" around town - nothing serious but you notice the difference).

It's such a simple change, and costs just £50 or so and can be done "whilst you wait" that I've decided to have it done, and if I don't like it I'll have it taken out at the next service.

One great thing about the Noble is that the factory are providing all sorts of modifications for us users so that we can all customise the setup for our own preferences. As you rightly say everyone is different, but to say that the current brake, or indeed anything else, setup isn't spot on for the "middle" compromise user is, to me and all the other owners that have put 100,000's of miles on the car just not reflective in their reports, both on the owners list and on the few websites dedicated to the cars.

You'll love it, and it sounds like 1G racing are going to be a great dealer for you in the US.

Sorry, I don't understand. Why would it be a easy shot? Please explain. Surely if you are a 'name' driver or roadtester then we would give your opinions some credibility rather than going round in circles with you alluding to be a force in the motoring world.
