Evening!
Is there a guide to taking caliper off/replacing pads on the front (and rear actually, assume they're equally unusual...)
Had a look today and it seemed like the pads were held in by a clamp, is that all holding them in place? and you can remove the outer 2 calipers with 4x bolts each side...although these bolts seem to be the only imperial ones I've found on the car so waiting for spanners to arrive.
Brakes were sticking on a bit, managed to loosen the inner caliper off a touch so can wheel but want to go over properly.
thanks!

Early 2024 I had squealing front brakes. Upon close inspection I found the metal backing plates of the pads to be a too-tight fit within the caliper. The pads weren't free to move away from the disc. Removing some metal from the edge of the pad did thr job. Perhaps your sticking on problem is similar?

Possibly?
I need to figure out how to get them apart before I can check 😂
Assume pistons just push back in as per normal calipers?

Yep Dunlop system!
Different to anything I've worked on before, shame there isn't a Haynes manual or equvalent for the Fulvia!

There is a Dunlop braking system manual for Flavia (same). Contact Chris Hopkins - libraian as he may have a copy to sell....

Hi, only just seen this post. I have recently rebuilt my series 1 Dunlop brakes and had a few issues with parts supplied from Italy - notably that the pads did not fit the calipers! As someone else noted, I had to adjust the metal backing (with a grinder!)to get them to fit at all. Once fitted I found that the pads had a coefficient of friction similar to a block of concrete ie next to nothing (but probably did not fade at all).
I would recommend EBC Brakes Greenstuff DP2120 pads which are sold here in the UK for Jaguar E-types and others. They fit the calipers properly and provide excellent braking performance for everyday driving.
I have also completely dispensed with "Lancia" (all pattern parts I believe) master cylinders - when I got the car it had a master cylinder from a Ford Transit (!) and the ones from Italy were all for left hand drive cars (Omicron do an adapter to bring the master cylinder back upright, although I made my own), but it took four changes of seals before I could stop them leaking. Even then the braking performance was miserable before I changed the pads - it was frankly terrifying to drive the car in modern traffic when people in vast SUVs think it is a good idea to jump out in front of a 50year old car. I changed the master cylinder to a TRW GMC234 (for a Triumph TR5/6) and related servo. I had to manufacture an adapter plate and rod to make it work in the Fulvia but the effort was worth it, it now has brakes up to modern standards on the new pads. The braking balance front to back is good also, at least I have not managed to lock the wheels up yet! I hear this was a issue on the later cars with Lockheed brakes.
Obviously if you are a stickler for originality this is not a great idea but I use the Fulvia as an everyday car so performance trumps originality! Good luck with your brakes.
John
