Four Piston brembo's

I have a set of these in black (with alfa romeo in white on the outward face of the caliper) and i think they came off either a 156 or a 166

Now my problem is that im trying to fit them to my Series One Peugeot 106 Rallye, but i cant find any information on the discs that they use ie diameter, thickness, offset etc

Could one of you kind folks point me in the right direction please

Re: Four Piston brembo's

Black with white isnt off a 156/147 or GT so pass, sorry.

Generally Brembos on these Alfas fitted 305 or 330mm discs

I dont have the specs for the 166, sorry

Re: Four Piston brembo's

get brembo calipers and discs from a 406 coupe, they bolt straight on to the 106

Re: Four Piston brembo's

lol, the price u paid for the calipers will be offset by the cost of discs and pads imo.

you can look at disc specs in the brembo catalogue

Re: Four Piston brembo's

are they lug or radial mounted?

what space is the inside opening of the caliper, take 2 mm off that & thats the max width

they could be from a 166 which uses 310mm x 28mm discs .... iirc.

156 uses 305mm x 28mm or 330mm x 32mm

Re: Four Piston brembo's

not a clue on how they are mounted bud, i didnt take them off (which riled me abit as i like to see how things are attached) there are two bolt holes on the caliper itself ? I'll have a measure between the pads and see Then i'll check if Peugeot have any discs of similar thickness although saying that the max diameter will only be 283mm

Re: Four Piston brembo's

They will be lug mounted and probably off of a 166.
so 310x28 disc.

The only radial mounted calipers were red and on a GTA.

Unless you have found a set from a Crosswagon, which is unlikely.

Re: Four Piston brembo's

the 2 mounting holes will be at least 100mm apart, possibly 130mm.

the peugeot will not match those diameters.

imho you need to get the 406 bits.

Re: Four Piston brembo's

166 calipers, fit on a 310 x 28 disc. Mounting lug centres are 150mm, mounting bolts are m14. Just had some brackets made to fit some on the stratos rep using 285mm 164 discs.

Very VERY unlikely.
But it would depend on the size of disc you use and the design of your rims.

Re: Four Piston brembo's

i had 282mm discs on my old rover with 15 wheels.

if the wheel design is right they will fit. almost certainly with the fore mentioned hub centric spacers.

Re: Four Piston brembo's

using with 282 x 22 will be ok, 310 x 28 won't fit.

Re: Four Piston brembo's

also using a caliper designed for 28mm disc is UNSAFE when used with a 22mm wide disc..... when the pads wear out the pistons may 'pop' out

Re: Four Piston brembo's

Good point Sears re the pistons.

My calipers/disc combo fits nicely under a 15" rim. They won't fit under any 15" rim though,

Yep, the make and type of rim is critical if you want/need to keep a small rim.
AP make a 4-pot setup for 156/147 that will fit with 15" race rims with 295mm discs, but are unlikely to fit under 15" road rims.

The 305mm Brembo setup only just fits under 16" road rims and runs VERY close to the outer ballance weights.

Re: Four Piston brembo's

Caliper brackets are the hardest. Radial mounts are easier to make.

Have you done any calculations for your m/cyl and caliper piston sizes? Just bolting anything on is a recipe for disaster

Re: Four Piston brembo's

I think ive got it sussed yay! I've been busy researching this all morning, and i think that by using Citroen Xantia V6 brake discs (288 x 28) the calipers should work as normal (as they would on an Alfa)

I'll have a measure of the inside wheel diameter, do some working out and then see if they will actually fit on the car. I hope they will, i like being different. And Alfa Brakes will make my little French rocket cool

I shall update with my progress when there errrrr is some progress

I wont be using the standard 1.3 Rallye Master cylinder as well its a bit lame even with the 266mm 206 GTi Brakes that are on there now. I intend to use a 306 GTi6 master cylinder as they work well when used in conjuction with the 406 Brembo upgrade, braided lines will be going on too. im no cowboy i like to make things work and to make them work properly

Strat, you wouldnt perchance own the lime green Stratos Replica with the Alfa V6?

Re: Four Piston brembo's

i would keep the small mater cylinder tbh

the gti-6 m/c and 406 brembos make for digital as **** brakes.

really hard to get used to.
