Posts: 9,867 Thanks: 117 Trader Rating: 0 ![]() | Brake caliper rewind tool - clockwise or anticlock? Been looking to get one of these as I'm doing the rear pads and discs soon. There are different tools for the left and right hand thread ones - which does the Barchetta have? I can't be bothered to fiddle on with the little block tool (or pliers as I have previously) so was going for the proper one - they aren't that much more expensive. So, anyone know which I need?

Posts: 13,982 Thanks: 1490 Trader Rating: 5 ![]() | Re: Brake caliper rewind tool - clockwise or anticlock? Do Barchetta pistons need to be wound in? The Barchetta manual suggests both front and rear pistons just push it. It shows how to make a tool but it's only a metal plate with a threaded hole through the middle and a long bolt. Most older 1970s - 1990s Fiat rear calipers, that I remember, had a slot machined into the face of the piston that a large screwdriver would fit into. There was also a smaller slot that needed to be at the top of the piston for the handbrake mechanism to work correctly. Not sure if this aplies to the B' though. Dave.

Posts: 416 Thanks: 7 Trader Rating: 0 ![]() | Re: Brake caliper rewind tool - clockwise or anticlock? The front pistons slide back , you need a tool to wind in the rear pistons , i bought a universal tool from halfrauds £20 , both sides screw in clockwise .

![]() | Re: Brake caliper rewind tool - clockwise or anticlock? Yup, easy job with the right tool! Front callipers push back easy as pie with a pair of pipe grips but rear ones take a lot of effort to wind back. IIRC they are a different screw for each side but its ages since I changed mine so could be wrong! Leave yourself a little extra time as the screws that hold the rear pipes in place will have corroded and will need drilling and tapping.

Posts: 9,867 Thanks: 117 Trader Rating: 0 ![]() | Re: Brake caliper rewind tool - clockwise or anticlock? Digging up my old thread, but I bought one of these: http://www.lasertools.co.uk/item.aspx?cat=518&item=356 for a bit less than shown there though. I wouldn't even attempt the job without one after the problem I had trying it on a Marea. Changed the discs and pads, really easy with the wind back tool. Only problem was some nugget had done the job previously and ripped the boots on the pistons. Got in touch with these fine gentlemen: http://www.brakesint.co.uk/ who supplied me with a caliper kit - piston seals, boots and nice little rubber bodgy things for the bleed nipples for just over £20 delivered ![]() Have now overhauled the calipers, which look to be in good shape so should last a while now! One thing I would strongly urge, if any of you are trying this then please make sure the rubber boot will turn freely on the piston before winding it in or out, otherwise you might end up needing an overhaul kit too.

Posts: 2,636 Thanks: 223 Trader Rating: 0 ![]() | Re: Brake caliper rewind tool - clockwise or anticlock? Holy Thread Revival, Batman! So, I've removed the rear pads to clean everything up pre-MOT, and although I've done this job before, I can't remember whether the pistons both rewind in the same direction (as is suggested earlier in this thread) or whether the NSR is anticlockwise and the OSR clockwise (as with some other Fiats/Alfas). Can anyone help? I don't want to knacker my calipers! Cheers, Gareth

My generic caliper tool (inherited aeons ago from my f-i-l) has 2 pieces, clockwise & anti-clockwise. Problem is, I can't remember whether I used them both last time, or just one of them. ![]()

Posts: 4,418 Thanks: 322 Trader Rating: 0 ![]() | Re: Brake caliper rewind tool - clockwise or anticlock? I concur, both sides clockwise! Another tip. My nearside calliper wound back fairly easily but the offside one was more stubborn and I couldn't get the necessary purchase on both the wind back tool and the calliper to effect any decent movement. Then Plan-B dawned on me. o Remove the calliper carrier o Remove the disc o Put carrier back o Loosely assemble wind back tool into calliper carrier recess o Refit calliper to carrier Bingo! You now have a securely mounted calliper with wind back tool in place and can easily wind the piston back.
