I've been trying to replace the rear disc pads but I can't get the Pistons to move back. I've not taken the calliper off the car as yet and was wondering if there is a tool for the job anyone could recommend? Many thanks

easy to take the caliper off.....then use a g clamp to squeeze the calipers back in. But if very old then an overhaul is worth while for another 40 years use...

Thanks Lancialulu, I'm sure you're right re taking the calliper off. After a bit of googling I've noticed a tool called a piston spreader, not expensive but wondered if they were useful on a sticky calliper?

The cheap piston spreaders tend to bend if the pistons are sticky. As Lancialulu says G clamp is best and if you already have one it is a no cost option.

Not relevant to Fulvias but for the sake of completeness on later cars with self adjusting hand brakes acting through the main calliper piston (e.g. Dedra) it is important to use a proper tool because the piston has to wind back onto the internal adjuster as it is retracted. Still an inexpensive and generic tool available from any parts shop.

Can I just add an advisory to open the bleed nipple when retracting caliper pistons, to avoid the risk of damaging the seals in the master cylinder by forcing fluid the wrong way past the seals! Good Luck, John

Yes, it is best to open the bleed nipple. I tend to clamp the flexible brake pipe to make sure the displaced fluid doesn't go back up the system.

Many thanks for all the advice. In the end I improvised with a small pry bar and strips of wood, opening the bleed nipple to relieve pressure. I used green stuff pads which seem great but they didn't come with a fitting kit, as luck would have it I'm missing a set of pad retaining springs and the pad retaining pins are different on each side. I'll try the pad suppliers EBC, but any recommendations for a supplier?

Hi from memory the rear pads on a S2 are the same as some MK2 Escorts, green stuff pads are great when hot, but not very good cold
