how easy is it for everyone else to lock up the front wheels on their Fulvia because its damn hard for me.
Only can get a little chirp out of them on a dry road.

Is this normal or should I be striping something. I already have braided hoses and there is no sink in my pedal.

what do the masses say,

My series 1 2c with Dunlop brakes also, (unless on a loose surface) doesn't lock the fronts, but as there is no brake limiting valve on the series one, I can sometimes get a bit of a squeal out of the rears.
I also have no sinking of the pedal and she stops very well, anyway if they are pulling you up ok why are you worried about locking the wheels, surely getting the braking required without locking the wheels is an ideal situation.

Absolutely unanswerable question without knowing what tire you're running, among other things. For example, with the 185 Michelin XAS I run, and Ferodo F3000 pads, I can lock the wheels easily. If I were running 225 street-legal soft autocross tires, it would be much harder to lock them.

Fulvias were engineered from the beginning with perfectly adequate brakes. The standard production brakes, with standard pads, on standard 80-series tires, all as originally engineered, lock the fronts in any emergency stop. Period. In fact, absent ABS, that's the measurement standard for adequate braking for the tires you're running--being able to lock the wheels in an emergency stop on dry tarmac.

But if you cannot lock your wheels in an emergency stop, we need more information before we can even begin to guess why. What tires are you running? What brake pads? What have you modified other than the hoses? Has the master cylinder been rebuilt?

The masses want more information...

A long time ago when my Fulvia Sport s2 was in really good condition the brakes were very impressive and even with big tyres I could lock them (if I was clumsy).

Air, poor servo (vacuum leak), poor discs and wrong pads are all possible reasons. If the pedal is really firm it probably isn't air.

Hi everybody,
Mine is hardly to lock the tire normally. After appropriately heated the brake, the feeling of the brake becomes better, therefore I think it is because of the brake pad which I use in my case. The master cylinder of the brake and calipers were overhauled the other day. It seems nothing wrong the mechanical things. I should try to use Ferodo F3000 pads or something else next time.... :cheers:

Kei,

It sounds as though your pad compound is too hard; what you're describing sounds a bit like a race compound.

You could do worse than try some EBC Ultimax pads. These are the label that EBC give to their version of the manufacturers original pad. I have tried them on a couple of cars and they are excellent. They are not expensive and they do not eat the discs. If you find they are fading out under heavy braking then go to 'Green Stuff' or 'Yellow Stuff'.

I have used Ferodo DS 2500 and DS4003 on my race car which has small pads. DS2500 is good from cold and remains good with heavy use. DS4003 is truly dreadful when cold - so bad that the only way I could get the brakes to work was to leave my foot on the brakes for almost the complete warm-up lap. Once warmed they worked well. I would be cautious with DS3000 as they are a higher temp pad than either of the ones I have used. The Fulvia 2 has a big pad area which takes some heating.

Hi Ed, Hi Bill,
Thank you for your comment. I am not sure mine is a race compound but it is not my driving style. EBC brake pads are currently used for my other cars (Green stuff for MB 202, and Red stuff for Fiat coupe 16V turbo), and they are totally satisfied for me. So EBC is actually my another option....

I'd say that'd be the right choice.
