Aaaaaaaaggghhhh
I have just bought a set of Ferodo DS pads, for my 03 JTS, the fronts fit fine, but the rears are too big. The guy fitting them reckons the one's on mine are the same as ones listed in his Lockheed book under a 147, 1.6 or 2.0.
I bought FDS995, which are supposed to fit a 2.0 156, from 97 onward. :(

Anybody had a similar experiance, do the JTS Cars have 147 brakes, why the hell would they make them smaller FFS, it needs MORE brakes not less.

I need to check the Chassis numbers with the local parts department now, but it doesn't look like I can get DS's for the rear at all. :(

Good question. :rolleyes: Sorry about that Mitch.

Rather than go on what the calipers 'look like' it is worth gettng the number of the back of the pads already on and checking what they fit. That way you can be sure...

Why should you calipers be smaller? I think Alfa have always had a habit of bunging on what they have left in the parts bin when they get shorty on stock :rolleyes: You should see what they do to 155s - ask Wrinxy!

From mid/late 2001 all 156 used the same rear calipers as the 147.
FDS995 are for pre mid/late 2001 156.

If its any help my old 2.0 TS (1999) had 1.8 calipers on the front, that was fun and games working that one out, just maybe your rears suffered the same parts bin problem my fronts did????

Regards

So did it also have solid discs?
Because the vented discs fitted to 2.0TS will not fit into the caliper used with the solid discs on early 1.8TS 156.

no the rear calipers & discs changed in late 2001 when the 276mm rear disc was introduced.

David C,

Discs F + R were changed at the same time and they were definately vented fronts and solid rears

Thought as much, looks like I will have to use different pads on the back to the front now, not ideal. Anybody any recomendations, are the SuperAlfa ones that EB do OK, or should I look at green stuff, or even OEM Alfa ones??? :confused:

With Ferodo DS-Performance pads on the front, Ferodo Premier may be a good option for the rear.

(idealy on a FWD car you want a lower friction pad on the back)

but that info is wrong!

All 147s use the 251mm rear disc that the 156 used to use but with a different caliper & pad (except the 147 GTA which uses the 276mm rear disc).
July 2001-> 156 use the same rear pad as the 147 but with a 276mm disc.
pre July 2001 156 use the 251mm rear disc with the same pad as the 166.

Hi Mitch,
You need Fxx1349 for the rear of a facelifted 156. This is the same as for the 147 and, IIRC, Lancia Dedra. I couldn't find DS-Performance FDS1349 so fitted DS-2500 (FCP...) all round; braking is much improved over OEM pads but still could be a lot better.
Cheers,
Simon_S

Not necessarily. True, you need less braking effort on the rear, but that is taken care of by smaller caliper pistons & a smaller disc.

Vehicle manufacturers, brake manufacturers & friction material manufacturers work together to ensure that, among other things, the front/rear brake ratio is optimised for the wide range of conditions the vehicle will encounter. If the OE rear pads have the same friction level as the fronts, which is the case more often than not, changing that will affect braking performance - it will also be in breach of ECE Regulation 90!

Info direct from Ferodo (in Italian!):
"Scelta della Mescola
Una regola che potete utilizzare con le mescole Ferodo Racing:

Vetture a 4 ruote motrici stessa mescola per anteriore e posteriore
Vetture a trazione posteriore stessa mescola per anteriore e posteriore
Vetture a trazione anteriore mescola ad alto coefficiente d'attrito sull'anteriore (es. DS3000) ed a minor coefficiente d'attrito per il posteriore (es. DS2500 o 4003). "


In English it says:
4WD: same friction front & rear
RWD: same friction front & rear
FWD: lower friction on the rear (in this case talking of DS3000 front with DS2500 rear, but DS2500 front & DS-Performance rear is the equivalent with road usable compounds).

Well it looks like I'm going to be contravening rule ECE 90 then. :eek:

DS pads are not available for the rear of 147's and later 156's, DS2500's are a track pad and are not technically legal for road use (I understand).

I have ordered some SuperAlfa one's from EB for the rear now, the DS's which didn't fit will have to go back.
