Title: Fulvia Sport S2 Rear Disc Brakes Post by: kevbo on 01 April, 2016, 11:29:17 AM 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 Title: Re: Fulvia Sport S2 Rear Disc Brakes Post by: lancialulu on 01 April, 2016, 11:42:29 AM 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...
Title: Re: Fulvia Sport S2 Rear Disc Brakes Post by: kevbo on 01 April, 2016, 05:20:08 PM 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?
Title: Re: Fulvia Sport S2 Rear Disc Brakes Post by: dhla40 on 02 April, 2016, 04:02:45 PM 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.

Still an inexpensive and generic tool available from any parts shop.
Title: Re: Fulvia Sport S2 Rear Disc Brakes Post by: Jaydub on 05 April, 2016, 01:55:32 PM 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 Title: Re: Fulvia Sport S2 Rear Disc Brakes Post by: frankxhv773t on 05 April, 2016, 10:09:24 PM 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.
Title: Re: Fulvia Sport S2 Rear Disc Brakes Post by: kevbo on 06 April, 2016, 04:55:00 PM 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?
