B-b-ber BREMBOS!

I've opted for standard nuts to go on the back of the hub bolts and just use thread loc as I feel the heat may effect Nylocks.
This is what I went for in the end, impervious to heat and not as deep as a Nylock either which will only work if the thread of the bolt passes fully through the Nylock nut.http://www.ebay.co.uk/itm/121756587262?_trksid=p20...

I decided I couldn't wait and I have enough clearance with caliper spacing to get away with it for a day or two so fitted everything up properly today.
Bled brakes and so far after a few very local test drives their bedding in nicely.
No noises or rattles, and a very even sense of brake pressure on each wheel,,
Sat at the pub having steak with the grandson and he helped me park leaving the Brembo name visible,,,
awesome and my car feels more refined already. So far I'm over the moon.

I used nylocks when I fitted mine 3 years ago, nothing has come loose
That's good to know, this is actually a better fix than the original set up with the addition of the nut on the back. When separating the Caliper from the Caprisport bracket,, the bracket weighs almost as much as the Caliper, Dave's right when he says the Calipers are actually very light.
I've put my brake pads in and left the pins dry for now as I'll be removing them again early next week, should I smear a touch of copper grease on the pins on final assembly?
I say it's easy but I'm constantly asking questions,,, maybe that's why it's easy. Thanks boys.
The feel of the brakes/pedal !
As I've experienced a few tivs with these Brembo brakes I'm glad to confirm mine feel very much the same,,
Longer pedal travel to bite point as I assume it's pushing more fluid but very linear and progressive.
I will,re bleed just to be sure as it took an age to get the fluid through, I need to undo bleed screws almost one full turn to release the fluid and only worked it out at the end, I've also pumped about 1/2 litre of fluid through the lines to be sure it's all new and the brakes are working very nicely, smooth and just feel like a Ferrari.
,, I have no idea what a Ferrari feels like but it must feel good going by these beauties,,, Edited by ClassiChimi on Saturday 2nd April 21:44

With all that class engineering going on alun I was a bit concerned to see that cheapo bloody claw hammer laid on the ground.....I assume you were only using it to chip the rust off your outriggers !??????
Rich
Hahahahah Rich
I was wondering when someone would mention that,,, I do have a very nice forged hammer,, but me and the grandson used that old monkey metal as a tester for our Paris blue paint the other day that's going on our toy Jag, 
so when I asked for a hammer he gave me that one,, hey I don't need hammers,,,,, much 
The out riggers,,, glad to see Petes all jem'd up Rich
I've done everything else I might as well sort the ever existing problem,,, sooner or later.
My order was cancelled no problem.
Just to be certain... is this the kit I want?

I`m just wondering if these massive brakes you are fitting are going to throw the balance out ..The rears are tiny.
No is the answer, but its worth looking at another car using these Brembo GT four piston calipers to confirm.The Ferrari 360 (& 430) both use this exact same caliper, front discs on the Fezzer were 330mm vs the 324 we are using..... so fek all in it. The Ferrari also uses 330mm rear discs vs our 273mm ones, so on the face of it with the Brembo conversion we are under braked at the rear right?
Well no, consider the mid engined 360/430 has a weight distribution of 43% front 57% rear vs the Chimaera 50/50 weight distribution and you can soon see why the Ferrari needs those bigger rear brakes. The 360 brakes are 20% bigger at the rear than to 273mm ones we run, but it needs 20% bigger rear brakes because its carrying more rear weight bias by roughly the same percentage, consistently on the TVR the 324f/273r balance is perfect for the Chimaera's 50/50 weight distribution.
Perhaps a better example is a 2015 BMW Z4 E85 3.0si that while a much heavier sports car overall does share the Chimaera's 50/50 weight distribution, the BMW uses 325mm front discs and 294mm rears so not a million miles off the 324mm fronts and 273mm combo for us with the Brembo conversion.
There is no imbalance with this Brembo conversion, it's more a case that the strange standard 260mm front & 273mm rear setup TVR gave us was imbalanced!
If you'll excuse the punn..... "Brembo adopters are actually just redressing the balance"
I'dont do my research quite like Dave but I've checked out the Ferrari Calipers and yes there the same.
I'm getting the tiniest about of fluid leak from both outside bleed nipples, I've nipped them up as much i dare!
If they show any more signs of leakage what should I use to seal them. It's just coming up through the threads,,,
I'm happy to drain the fluid to remove nipples,, I see there's copper grease on the threads, should I use a tiny smear of copper gasket on the threads or is that a no no !
I've nipped em up and there's no more leakage but I'm not happy how tight they now are?
Ideas please.
i also fully agree with Dave's comments re balance, mine seems made to measure, front to rear balance seems to have improved immensely, I can't explain it and I've not tried pushing on yet but from just testing and local drives it's like silky and smooth, feel the brake pressure as you apply the pedal more, more of a feel of exactly how much brakes your applying,,, it's solid and exact, feels refined and after 4 years with the standard set up and a good few trackdays I've got a feel for them,, this is as Dave said a few pages ago,, night and day difference.
It's very subtle and not instantly anything very different but as they bed in,, oh it's very enjoyable to brake, even slow it's just lovely and progressive,,, as you experience the more refined ability of them it just gets better, driving enjoyments going through the roof right now

I'm sorry to hark on but these BREMBO brakes,,, phenomenal, awesome, quality, silent, outstanding, a joy to press the darn things,, I've never felt like that before but this is behond belief, 90mph in third, just brakes down to 30 mph in a very short distance, solid, planted, balance front to back seems far better, ive locked the rears up before, I'll never forgot it,,,
I've done only straight line tests but this is sublime, pure quality feel and massive assurance,, it's priceless and puts my cars performance into an entirely different league, even just local slow stuff, just a glorious feel to the brakes, a different car,, exactly the same but better. Brilliant.
Sooo happy with this one.
