166 Brembo caliper brackets.

**Steve Webb** · 14-12-11, 20:58

Hi all, I've just had another email asking where to get the mounting brackets for the 166 Brembo calipers.
Just out of interest, how many of you out there are looking for the brackets, or might be looking for the brackets in the future?

Cheers

For now I don't know what I am going to do with the brakes.
Haven't made up my mind what kind of big brake solution I want.

Maybe in the near future, but in the Netherlands there is somebody who makes these brackets regularly.

I am after a pair of brackets

Hi all!

As I've the calipers already I'm basically interested...

But I've one doubt:
I've also got the original bolts to the 166 brembo calipers and made some measurements concerning the lenght of the bolts.
I found out that the bolts are only long enough for a bracket that has a thickness of about 14mm (max. 15mm).....

The bracket of aluminium 7075 (the drawings are around here in another thread) has a thickness of 20mm. This means, that you will have to use longer bolts either, or you have to make the bracket thinner...

Longer bolts are not available everywhere...
If you make the bracket thinner, does it sustain the load???

Or should it be made of steel then?!?
But steel is much more heavy...

Saluti, Martin

any news about the thickness-problem?

**wrinx** · 06-01-12, 23:49

UK owners are using steel 10mm brackets and spacers...no problems whatsoever.

**fochista** · 09-01-12, 08:52

First of all: No news on the thickness problem yet.

I thought about making it out of steel instead of aluminium and make it just about 14mm or 15mm thick. Instead of 20mm.

First of all I'll make the bracket out of wood to check the fitment, next time (January or February).

Wrinx, are the spacers you are using with your 10mm brackets about 5mm thick???
If yes, that would match my intentions.

Best regrads!

Hi all!

It's time for an update here, isn't it?!?

First of all: The brackets have a thickness of 20mm.
I made the brackets out of wood first and checked the fitment, also with the wheels (TSW EVO 7,5J x 16 ET 35).

Take a look!

Tanti saluti, fochista.

I was forced to mod the calipers in order not to touch the rims.

**fochista** · 13-08-12, 21:51

I made a drawing of the brackets and searched for a company who could make the brackets for me. I found it. In the meantime I painted the calipers with black brake-caliper-paint.

The brackets are made out of "Vergütungsstahl V 320 42Cr Mo4" and i finished them using an epoxy primer and black paint.

**fochista** · 13-08-12, 21:54

I mounted the brackets with the original bolts (with new washers) from the standard calipers (105Nm).
Then the brake discs and then the brembo calipers to the brackets with bolts M14 x 1,5 x 45 steel 10.9 plus two washers with a thickness of about 3.5mm for each bolt (150Nm).

**fochista** · 13-08-12, 21:57

The calipers fit great and are exactly in the center of the brake discs.

I can order some more of these brackets if somebody of you is interested to buy a pair. Please have a look at "Classified" --> "Brackets for Alfa 166 brembo 4-pot calipers on a 155 Q4 and V6"

Nice!

Only one suggestion!

My recommendation is to put bigger brake master cylinder also!

Difference is not small: 22.2 (155) comparing with 25.4mm (166)

Shorter and nicer feeling on brake pedal.

**Steve Webb** · 14-08-12, 21:03

What brake disks are you using there? (166\coupe?)

**santino** · 14-08-12, 21:38

Alfa Mito, very similar like coupe.

**hf hpe** · 17-08-12, 08:31

I see in last picture that the pads are not within the brake disc.
We discuss it. The disc will over heating.

**Integrale** · 17-08-12, 09:46

I want brackets, but i have 147 GTA brembo brakes witch is 305mm. Is they the same as 166 caliper?

**fochista** · 23-08-12, 15:31

Thanks for your suggestion!

I also think this could be a good mod, because the way of the brake pedal is longer since installing the "brembos"...

I'm using the discs from the coupe Fiat 20VT.
166 doesn't fit because of 5 studs and different bolt circle (108mm) but surely they would fit better to the brake pads. I'll post pics later on.

Yes, there are small differences and probably the Mito discs fit better, because the measurement H is smaller... maybe the surface for the brake pads is bigger then?!?

First PIC is the "Coupe disc", second is the Mito disc...

Measurement D is also different, but it's only 0.1mm.

No. I'm 99 percent sure, that they are NOT THE SAME. You'll need to make other brackets for 147 GTA calipers.

These brackets fit only on 155 Q4 and V6 with the 4-pot Calipers from AR 166 V6 and the brake discs from the Coupe Fiat 20VT!!!
Maybe also with the Brake discs from Mito TB but this is not tested!!!

Yes, I'd like to discuss it. I made some additional photos:

At the first picture you can see, that the brake pad overlaps the inner shape of the disc surface of about 4 or 5 mm (Thats why I wrote "...probably the Mito discs fit better..." in post no. 21).
At the 2nd, 3rd and the 4th pic you can see, that the calipers are near to the disc in order to fit the 16" rims. Thats also the reason for the mod of the calipers which you can see on the pics at post no. 10 of this thread.
There is hardly no overlapping of the pads at the outer shape of the discs.

The other two pics should give an Idea of the wear of discs after about 1500km "hard road use" on the edge of the austrian alps (up and down between 400m and 900m over the see

. No highway. No track use, till yet. But on the coming Sunday...

I had no problems with overheating till now, except some smoke coming from the brakes at stopping after about 7km "downhill". It was so less that I wouldn't have seen it during moving on.

Best regards, Martin
