Hi we've been following this thread and slowly collected all the bits for it, this weekend we went to do the whole job (at the same time changed the rubber drive couplings, CV joints, ball joints, hub bearings etc) but came to mount the calipers onto the hub (mk1 caliper) and we have some major alignment issues, didn't have anything handy to accurately measure but it seems the disc is about 3mm too 'outboard' compared to the position of the caliper.

I think I've attached a picture to this which shows the problem.

Just for the information of the parts we've used

Car - 1962 Mk1
Swivel Hub - Standard disk mini (Car unknown, presume it is off an 8.4" disc later mini)
Bearings - Timken Taper bearings
CV joints - Disc CV joints, on the box they say 1275 is this correct?
Drive flanges - as far as we are aware they are metro drive flanges, (bought of ebay so they might not be correct, look to be about 12-13mm thick they did have the four lugs on which we had machined off)
Discs - as far as we're aware they are standard mini 8.4" machined down to 7.9", again bought of ebay
Caliper - Fiesta mk1

We tried tightening the castle nut as hard as possible, which brought the drive flange and disc in a little, but I doubt it's going to move in by 3mm. Another thing which we weren't sure about which could maybe affect the spacing is that our bearing kit didn't come with the split space (between the inner race and the inner grease seal) we put the one in from the old one, following the haynes, could this be the problem?

Anyone got any ideas what the problem could be, would like to solve the problem rather than putting in some washers, thanks for any help!

Also putting the brake pads in looks a bit baffling, anyone got any good pictures of this or can give us a few pointers? and another thing we messed up putting on the metal ties to hold the CV boot on turned out it was kinked and wasn't as tight as we thought, any good methods to making sure these are tight and secure?

cheers for any help!

I have several sets of front hubs 8.4" disc type, varying conditions, but most with balljoints and steering arms attached.

I have a couple of metro flanges also, either 1 or 2 pairs.

I am willing to drill the hubs out for you and grind the flanges for a small cost on top of the parts.

Posting this here, because I know alot of people doing this conversion cant find the parts required or may need the parts seperately so they can build up the complete conversion ready to fit to a vehicle.

If anyone needs anything, get in touch. Ive finished my brake conversion and these are all spares.

would the calipers of a 1.4 mk2 fiesta sport be ok or are they the same as xr2's?

[Finney]

Has anyone here managed to do the mk2 fiesta caliper conversion, and fit 10" wheels WITHOUT arches. If so, which wheels did you use?
At the moment i have the conversion done, and standard 3.5 steels, but I've had to have a 5mm spacer and grind the caliper to get them on and even now they're sticking out of the wings too much.

I was thinking that the cooper s wheel would have enough offset to sit under the wings without arches, but will it fit over the caliper?

are there and alloys anyone knows of that will fit without arches, perhaps 4.5" minilights??

thanks

Hi there, Im over in Canada and I just did this conversion using a set of 1978 fiesta calipers. Everything went well and I have some kind of slot wheel similar to wolfrace sytle, it fit no problem. The wheels I want to run are 5 x 10 Cosmic II. When I put them on and did up the wheel nuts they bound so hard on the caliper that I couldnt even turn the wheel. I tried grinding some off the face of the caliper (where it seemed to be binding). I didnt want to take to much off, but it didnt seem to help much anyways. Is anyone running a 5 x 10 Cosmic II ok, or any ideas what I can do.

cheers,

Ryan

You have found , as I did, and contrary to what is stated earlier in this thread, that Mk2 5x10 Cosmics foul the caliper. You have the Mk1 fiesta calipers and I used the Mk2 type, so what I did may or may not help you.

I ground down the caliper as you have. I found a quick coat of spray paint on the caliper showed up where the wheel was contacting. After grinding off what I thought was safe, I used washers on the wheel studs to determine what thickness of spacer would be needed to just hold the wheel clear of the caliper. In my case it was 5mm which is the max you can get away with using standard studs. Any thicker and you will need longer studs.

The only wheels I know for sure will fit (with no modification) are

Wolfrace / Cobra type 5x10 (Superslot ?)
Modern cast alloy Cooper s replicas (not the steel type) 4 1/2" x 10

This doesn't mean other wheels mentioned in this thread will not fit.

Thanks for the reply, do you have a picture of how much you ground off. I did the same as you but with spray Blue Dykem. I am just not sure how much can be safely taken off the caliper face?

[tommy13]

I ground metal from the area shaded green on the pic I have posted. The ground portion should follow the curvature of the inside of the wheel, which I think meant taking a little more metal at each end of the caliper rather than in the middle, as the fiesta caliper is made to fit a larger wheel. I don't think I removed more than about 3 mm of metal anywhere. Afterwards I blended the ground area back in with the rest of the caliper removing any flats and edges produced by the initial grinding, so visually, after painting, it is virtually impossible to tell any modification has taken place.

The important thing is not to weaken the caliper too much, in this case between the inner corner where the outer pad fits and the outside where the grinding is taking place. Unfortunately it is impossible to get any standard measuring devices into this area, or even judge it by eye so you must err on the side of caution. I have to admit to using little more than gut feeling when I did mine, several thousand miles later and after some hard use, all seems well.

I hope this helps but if you're not happy with any of this, my advice is don't do it,

Ya this exactly the area I have ground as well as the ends like you mentioned. I dont know if I have gone 3mm yet. I was hoping not to run a spacer but I think it will be unavoidable. As it sits right now with a 1/2" spacer it only rubs in one small area, causing a slight ringing sound.

[freaker]

i`m planning on finishing, my conversion, have the calipers for months now...

do the standard steel wheels fit or do i need to convert to alloys ?


and about the hoses for the conversion
did anyone ever have the hoses made with the banjo bolt for the angle ?

The standard wheels will foul the caliper unless you use spacers. If you are running arches you may be OK, but you should bear in mind that the metro drive flange moves the wheel outboard by 10mm and with additional 5 to 10mm spacers you can easily end up with the tyres protruding past arches. That being said, most alloys are 5" wide and will protrude even further, even though several will fit over the caliper without using spacers.

I cannot comment on the hoses, but I think most people have used the banjo type fitting, and are mentioned in other posts in this thread. Go to bottom of page, enter word "banjo" in the search box and press search topic. This finds all the info you will need.

[andyc142]

these are the hoses i used. they use just a standard banjo connection.

[andyc142]

are these the correct rear brake cylinders to use on this conversion? http://minispares.co.....INDER 11/16...

[dudiome]

hey guys, has anyone tried fitting these under original steel s rims? what mods would be needed? thanks

[andyc142]

i'm not sure, i'll try my old uns tonight and let you know.
