Hi i need to chage the pads on the back of the burstner i684, i was wandering if the rear brake calipers are wind up variety or simple push bak? I havent got the wind back tool.
Thanks

Hi
If by "wind back" you mean that you can wind the calliper piston on an internal piston thread back into the housing then no. The rear callipers are the same as the front brakes & as they are not used as the parking brake you just need to push the piston back into its bore as per the front. The hand brake is the drum in hat type inside the rear disc & has to be adjusted just like the normal drum brake through a hole in the disc housing.
I changed the front pads on our 244 just last year & it turned into a nightmare as Fiat had used locktite on the threads & luckily the neighbour had a near meter long ratchet & even then they were still tight as hell & I thought the bolts were going to brake before they came out.
Cheers

Coincidentally, I've just checked my X250 pads and realised that if/when the front pads need replacing it's likely to need some serious effort. the securing bolts require (from googling) a 14mm Allen hex socket and look tight!

In contrast the rear calipers are 'car-quality' and practically fall off

Just two small Allen bolts under rubber caps, I think they are 6 or 8 mm. With these two removed you can replace the pads and even the caliper.
The large ones hold the bracket on which the caliper slides, you don't ever need to remove that.

Were you actually able to carry out a pad change this way? The reason I'm querying is that I did remove these Allen bolts but still couldn't get the carrier free. I then had a look on the eLearn CD which says the large 14mm Allen bolts need to be removed to carry out a pad change.

As I mentioned, I've got a X250 base (so off-topic a bit from the thread title!) so wondering if it's a different procedure from the X244. If so it's a bit retrograde to make the pad changing more difficult

Yes, I replaced the pads and one caliper that had damaged seals. Also put a bit of copper paste on the rails so it will hopefully be easier next time.
It looks like the caliper won't budge because there is a small collar on the seating plane where you removed the small bolts. I used an old screwdriver and a hammer to get some slack, then the caliper could be removed and the old pads taken out.
