Oh bugger,, I've had mine off today to re Shim them,, all back together and pointing forwards, sorry bloke.
Oh and just to note,
N/s 1mm shim
O/s 1.5mm shim
To centre Calipers
So using very little and everything's looking very nice indeed.

I've been getting break squeal occasionally at slow speeds so today I re -shimmed my N/s caliper, if noticed that the n/s outer face of the disc wasn't really wearing much, I've only got the use of 0.5 mm Shims at the moment so removed a 0.5 mm shim from both mounting bolts and re tightened up, the outside face of the caliper is now closer to the disc, using feeler gauge I've got a slight lean on the caliper, botton to top, need smaller Shims to get accurate as this will twist the caliper as brakes are applied,
test drove the car and brakes are excellent but still some brake squeal at slow speeds,,, I'd just been doing some serious stops from very high speed, brakes,,, you can't f
k about,,, so they were hot,, will that extra heat induce the squeal,, it only seemed to be from the left side but now it seems like it's from the right.
Mm!
Could it be the pads are too hard for the pressure I'm applying, I've given them some stick and the pads have not worn very much at all but the car stops very well ?
Will a dab of mastic on the back of the pads help with the brake squeal, I know it's a good way to stop pad rattle but will it have any effect on squeal.
I'll try and do the o/s caliper tomorrow if I get time and see if it helps but I'm sure that ones centred well already!
What's causing the squealing, any thoughts will be appreciated. Cheers Al.

can anyone tell me the bolt spacing on the callipers ,is it 150mm?
150mm is the spacing of the 'Big Brembo' from the Alfa 166130mm, from the other Alfa V6 models...
112mm for the E38 BMW's
I have a pair of 130mm spaced brackets that I bought in error; I have the 150mm Brembo's, so had to make my own up, instead
£30 anybody.??

My Carbonic Lorraine pads are doing just the same - race pads are not the best for slow and gentle low speed road use. It's already starting to drive me mad - think I will swap back to Hawk front pads.test drove the car and brakes are excellent but still some brake squeal at slow speeds,,, I'd just been doing some serious stops from very high speed, brakes,,, you can't f

Same as me then. ??
Very odd!
Mine are making big noises but that was after a lot of hard braking,, I can let go of the wheel and it's braking in a straight line but under about 15 mph they start to squeal,,
They work very well indeed, I love the pedal feel and sensitivity of them but once they get hot the noise is loud.
I must have been doing emergency stops from well over 115,,, leptons and loads of times too, and there brill.
I'm driving the car to Central Tvr tomorrow for a windscreen replacement and it's all motorway so cold brakes,, see how they act under normal conditions before doing something with them.
I wonder if Adrian can paint em red,,,
That's a joke as I really like the black with my light colours,,, it looks made for it

Thought I'd give an update on my Brembo brake conversion,
I've had a few issues with some brake squeal and uneven wear on one disc,
Both have settled down and the disc seems to be wearing more evenly now the brakes have bedded in.
I'm over the noon with these brakes,
Effortless efficient braking that's confidence inspiring.
The enjoyment of driving my Tvr with such high class braking potential is just brilliant, exciting every time you apply them,
Slow driving or fast they are very enjoyable to use,
I've done a few upgrades to my Tvr now,, this is simply the best by far.
Through developing my Tvr I'm learning what makes the driving experience exceptional, as the car accelerates rather well putting a proper set of brakes on the car is a massive advancement in safety and it's just such a joy to use them,
My levels of wonderment with these upgrades incl my Mbe Ecu are taking the level of driving experience to a place seldom felt in my life time,,
Driving a car you are keen to learn about and slowly I've put some of it together it's like driving/riding a home built motor bike,, it's yours, you did it, it only lives because of your passions and desires,
I've driven better cars but nothing as good as this for the money,,
I'm having to pinch myself as I can hardly believe it's all come together so well.
The brakes are the icing on the cake that's elevated my cars excellence to a level that thrills me every time I drive.
Brilliant and I'd recommend a brake upgrade to anyone who wants to listen.

Real life test.
Having had my Brembo calipers and 324mm discs on my Chim for about 6 months I often look at the size of the fronts and keep in mind I'm not sure of the brake balance, I've done tests and been happy that it's actually a really good balance front to rear but until it's tested at an unexpected moment I'm never overly sure !
Well I had someone coming in the opposite direction and decide to turn right around a roundabout without indicating as I'm coming towards it. This is a wide road, dual carriageway with excellent visibility and at night, I'm being a tit and coming at this roundabout faster than I should, I'd clocked the car and assumed it's going straight on, about 80 metres from the roundabout I realise his speed has slowed and is in fact going to turn right and so directly into my path, so I hit the brakes hard, I'm maybe 50 metres from the roundabout at this point and doing 70 or 80 something, it's my own fault I know!!!!
I'm turning very slightly left as I'm doing this so the rear end balance is effected, well my car dips and I level up the steering a tad, fronts just stop the car so fast,,, I'm now feeling for the rear to step out as it's now light on the left rear but heavy on the right, but no such thing, I'm almost inclined to think the rear brakes are not working at all at this point as the car stays in line and in fact the front brakes are levelling the car and making this very dangerous and difficult stop test seem fairly easy.
My conclusion is
The original brakes on my car were as I'd always suspected, rear biased
I know from many brake tests on track etc that I could lock the rears easily if I hit the peddle too hard so would have to temper my braking especially if I couldn't line the car up in a straight line first.
The weight transfer with bigger front brakes helps the biase valve as its often when I first apply the brakes that they'd lock, once the fronts had bit then the rears would be ok but this was always an issue for me when really committing the car to a brake zone,
The incident the other day went from a heart in my mouth moment of complete fear to feeling confident I'd stop or at least slow enough to alow the fking dipstick a safe passage.
It's just one incident so hardly a study but I'm under no illusions, without the brakes I now have on the car I would not have been able so stop.
Ban drivers who don't indicate !!!
Thank you Brembo
The weight transfer and brake balance has improved in almost every scenario I can think of.
I bet you all thought I was about to tell you I'd smashed the car up no flipping chance,,, yet 
You can't underestimate the value of these brakes. Fantastic.

I take full responsibility for my actions which led to this scenario as much as anything the other driver was doing but for gordsake this is a main artery and an odd roundabout with only two exits at that, right or straight on so he/she only had one thing to do, but hey as a Tvr driver I'm always second guessing the feckers anyway.
My entry speed was way to fast so at normal road speeds it's unlikely the drivers lack of indication would cause issues but only because someone else would see the manoeuvre unfolding and take action. How can you expect to be given right of way without indicating your intentions, tail gating and incorrect use of indicators is to my mind indefensible!!
That and speeding in inappropriate places.
We all make mistakes and I was speeding towards that roundabout late at night thinking I'm straight lining it with no traffic around me and no cars able to come from the left so safe,,, the road layout allows me to see the other car easily so it's only when I'm say 100/120 yards away can I pickup in the dark the cars actually in the right hand lane which triggered my reaction, he's not even on the roundabout at this point.
Very close thing because of both our mistakes.
The fact I went from 70 ish to about 15/20 mph in a matter of metres and not much more than a couple of seconds was really impressive and changed my mood from fk st crap to no problem mister and I sort of didn't even flinch but the heart beat told me it was a close thing!
For all the drivers of our cars with standard brakes, they work well but watch for the rears biting you in the ass,
Maybe it's just my car but it was rear biased just at the wrong moment sometimes, it's not anymore and I think it's the best money I've ever spent on the car.
