Title: help required Post by: bill on 27 May, 2009, 04:34:29 PM hello once more, decided to make my own brake pipes as the nearest supplier is a long way from me.I have just bought a clarke flaring kit along with a coil of pipe and the male ends ( unions?) the problem I am having, the male ends are so tight when trying to screw them into the flexi, hose. I do not want to damage anything. the guy in the factors said they are the only ones they supply. could these be a different thread? as usual any help will be appreciated.
thank you . bill.

Title: Re: help required Post by: Peter W on 27 May, 2009, 08:20:18 PM Had the same problem myself a few years ago and discovered that the Fulvia brake pipe fittings had a courser pitch than those provided by my local factors. I believe the sizes were 1.25mm & 1mm (can't be sure unless I go down to my garage and measure them). Had to travel further afield to find a more comprehensive stockist. Not to be confused with the imperial fittings on earlier British cars.

The standard pipe fittings are 10 mm thread diameter by 1 mm pitch, ie, the distance between the threads. However Fulvia (and probablt Flavia too) are 10 mm by 1.25 mm pitch. Wahteber you do, don't try th escrew the 1 mm threads into the 1.25 mm holes because you'll damage the threads forever. No idea where you get new ones from because I reused the ones which were on my original pipes. They need careful removing!

Title: Re: help required Post by: Richard Fridd on 28 May, 2009, 05:30:20 PM forgot to mention; it will also be wise to check the length of the replacements are correct.if too short the pipe will not seat properly.richard
Title: Re: help required Post by: bill on 28 May, 2009, 06:29:20 PM hi, thank you for the advise and help. I managed to find some nuts from an old motor factor, they were just a little tight on the last few turns hope they will be ok. That was a good point re. the length of the nut.
next job to overhaul the master cylinder I have it on the work bench ready, one thing I have learnt you must have patience when working on an old car like this. once again thank you all. regards bill. Title: Re: help required Post by: davidwheeler on 28 May, 2009, 06:43:38 PM Omicron have master cylinder repair kits. It is not a difficult job but take a digital photo or two as you dissasemble the cylinder. I had trouble with the brakes binding on and discovered I had put one of the seals in backwards!
Title: Re: help required Post by: Richard Fridd on 28 May, 2009, 08:34:38 PM just a thought;please dont force anything on that mastercylinder.the first one i tried to disassemble was difficult because i almost overlooked the threaded 'stops' which are accessed in the resevoir machined areas
