Anyone know of a 405 fitted with the 406 Brembo 4 piston front brakes? Haven't got a clue about the disc offset sizes of the 405/406 so don't know if it's a viable mod or whether theres no chance of them fitting

yes - mine .


it's a T16 though, don't know if the hubs on the mi16 are the same (i guess they are),
but the calipers and 305mm discs are a straight fit! .

you do need at least 16" wheels with a lot of space for calipers though!

Ooh thats good news!

I did read somewhere (not sure if its true) that the 4x4 and 2wd Mi front hubs are different, but hopefully they are all the same.

Did you just take off the old discs and calipers and simply replace with the Brembo and 305mm's then?

yep... i've had to make some L-shaped pipe extensions and get 20mm hubcentric spacers though.

but still, i'm not sure about the hubs... you would need to try it.

on 205 gti 1.9 hubs, they fit using 283x26 (pug 307) discs, but that's not what you want ideally, is it?

What is best disc and pads complet for normal size 195/55 R15, and does it fit immediately. Are there big differences to standard braking.

Thanks in advance

Best to use original discs and pads becuse of weight and fitment, and abs probably, is it so?

ABS doesnt work off the disc or caliper, so you can upgrade all you want

not 100% on this but I think a gti6 setup fits, and if they dont I'm sure the 406 estate calipers and discs will

306 setup doesn't fit but 406 V6 & 405 T16 283mm brakes should.

Yes, but it is heavier for the wheels, so unsprung mass is higher, maybe same size but newer materials(model)

yup as cyberneck said the 406 v6/sri or even td setup fits the 405 there 2 sets at my local breakers so im off to get some next week end...

I had a set of GTi6 brakes on a 4bie, but they were badly fitted with washers etc.I think i read somewhere that Xantia discs are the right offset for fitting the brembo's to a 405?

no... on a 405, at least mine, Brembo's fit straight on with their 305 mm discs.

But aren't T16's hub offset slightly different to Mi16's? Or is it just the wheels having a different offset giving a difference in track alone?

I'm sure a Sweede did put Brembos and the 305x28mm coupe discs straigt onto his 405 Mi16 with no problems at all.

If I didn't have too little spare time at the moment I could testfit my spare brembo set onto my 405 Mi16 but can't seem to do that before july.

Edit: regarding the unsprung weight. Sure the discs are heavier because of the extra size, but the calipers at least seem to be lighter than the cast iron standard calipers...

It's a straight fit with the 406 305mm discs on a 405.

On a 205/306 you'd need to use the 288mm Xant or 283mm 307 discs.

All 406 breaks wil fit with no problems on anny 405.

We fitted Brembo's on the 406 V6 Sedan.
En the old sedan breaks fitted now on te 405!


Nice 406 V6 sedan...






T16 rims


Original 15" mi16 rims

Nice pics, love those T16 wheels! Is it a standard Mi16 you have? Any other pics of it?

Welcome to the forum by the way. Could you please enter your location into your profile please

they're not T16 rims, just V6 saloon rims

reminds me I must get round to trial fitting the 406 estate 283mm setup I have in the garage!

Not just "saloon rims" on the 406.
These are the 406 coupé 2.2 HDI rims (Hoggar Speedline - 7J × 16" ET 12).

And on the 405: original T16 Speedline's (6.5J × 16" ET19)

The 2nd from last pic dude!

I've seen those picutres somewhere... just can't remember ;-)

@Jer309GTi, its a chipped 2.0 SRI with brembo's and T16 rims

No, we fitted 2.2 HDiF coupé Brembo's on the 406 SV 3.0 (Ø 305mm),
the old 406 brakes fitted now on te 405 SRI! (Ø 283mm)

Guys,

I am trying to fabricate the L-shaped pipe extensions to fit the 406 V6 brembos on a 405 Mi16.
Could you please advise on the sizes of the extensions needed for fabrication?

Many thanks indeed!!!!

So the Brembo's definately do not fit under standard Mi rims?

What brakes would be a direct fit and would it be worth the upgrade? I was just thinking about getting uprated pads and fluid.

Ta

No, Brembo 4 pots calipers (Ø 305mm) does not fit under standard 15" Mi16 rims, 16" and ET12 is required.

406 saloon / break calipers (Ø 283mm) wil fit in 15" rims (ET20).

Anyone?

anyone what?

I think he's asking "What brakes would be a direct fit and would it be worth the upgrade?"

Personally I'm a bit tight over brake upgrades. I'd probably think differently if I was a track fiend hanging out at Castle Combe at every opportunity, but I reckon most apparently poor brakes are just caused by badly deteriorated components. Can't deny bigger makes mean better stopping but then you have more unsprung mass and the extra rotating weight is similar to adding weight to other spinning engine items like the flywheel.

Thanks XU10. For some reason I couldn't see your post whem I bumped it.

Kris. Good point, just trying to guage whether or not there are any later model items that go on easily and are worth doing.

Again, anyone?

What L-shaped pipe extension ???

406 Brembo's fits perfect without any modifications...

I gave my standard brakes a complete overhaul when i got the car (new discs, Ferrodo Premier pads, greased up all of the sliders and replaced the fluid) and they worked perfectly, the pedal feel was excellent and they really pulled the car up well. They were perfectly adequate for the cars performance and weight and you really don't need anything larger for the road.

Sorry mate, but you could fit a pair of small 4-pot Wilwood dynalites (which would fit under stock 15" rims) with disks having aluminium center bells, and they would make a world of difference, while weighing probably less than half of stock system!

L-extension for brake pipes - around 10 cm length should be enough.

Many thanks mate!!!
What about the length of the shorter piece? Any difference?

Dynalites are absolutely wank. They're cheaply made American garbage, the pistons seize after about 1/2 hour of use and they're so weak the bodies bend even on a braking system with no servo assistance. To be frank i would rather hang a coat out of the window and use that as a brake than fit a set of dynolites to my car.

Every car i've ever worked on that has had them fitted i've binned them off in favour of some AP brakes.

No need to be that articulate, mate )))

Dynalites were just a figure of speech. Brembo, AP etc - any of them would be less than half the weight of the stock caliper.

Only proves my point.

Fair enough, i just really hate them. I had someone say to me once "ah i'll buy dynalites because they're cheap" Why the hell would you want cheap brakes though, it's like buying cheap brain surgery, you'll get something but it'll do some serious damage sooner or later.

The shorter piece should be a cm or two long (or short ).

If I was going aftermarket I would do some research on the kit hiflowheads sell

6 Pot brake kit. (discs, comp Pads, braided hoses), fit std Alloys 758.00 (pounds)

http://www.hiflowheads.co.uk/performance/mi16.pdf

Just thought that some of the later cars would have more modern brakes that work better without necessarily being heaver (just through an improved, more modern design). Which would go on easily.

If not I will just get better pads and fluid for now as the standard brakes work quite well, especially now the car weighs less.

You really only need to go bigger for two reasons.

1) Heat: larger brakes will dissipate heat better due to a larger surface area, be careful tho because if you have small clearance between the caliper and the wheel you will get a lot of heat transference into the wheel which will effect your tyre pressures.

2)Mechanical Advantage: you can generate more force on the disc, so if your unable to lock you wheels you could benefit from larger brakes.

You do however introduce a bunch of problems particularly if you upgrade your master at the same time.

Changed piston total area vs factory will effect the pressure working on the disc. Increasing the piston area will increase the force working on the disc. Increasing the master will DECREASE if the force working on the disc.

Changing the front brakes to larger brakes will alter the brake bias of the car shifting it forward, and increasing the master will reduce the effectiveness of the factory rear brakes.

I'd say go for the smallest brakes you can get that allow you to lock the wheels and with good pads and some brake cooling you would be better off.

u can replace with the 406 phase 2 front discs and calipers as they are having bigger pistons, dics and much bigger pads and they fit straight on the 405 hubs without any problems and if u want a very good set of pads, u will need the green stuff pads which are designed for performance
