caliper upgrade

Yes, standard master cylinder.

They do two piston sizes, one is very slightly smaller total area than the M16, compensated for by using a 260mm disk rather than the standard 245mm disk.

Edited to add...

That's the Ultralite 4 btw, uses a Lotus Elise pad which is a real bonus, you can get just about any pad compound you want and I should imagine it will be a popular pad size for a few years to come.

I also have Hi-Spec 4 pot Cortina lug mount.  Very pleased with them and no problems with Hi-Spec whatsoever, in fact they were very helpful and I would not hesitate to deal with them again when I replace the rear calipers.

Hmm, that is bad, mine spin quite freely even with new pads.

From the picure, it appears you've got a bigger gap between the left pad and the caliper than you have between the right pad and the caliper. Perhaps if you spaced the caliper to the right a little you would resolve the problem? What spacers are you using between the caliper and the upright? Are those Hi-Spec disks? Who fitted them?

Better, but I still question the reasoning for having pins inside the caliper. Smacks of a short cut to me, and that's just what you don't need on a braking system...

Yup, old Mr Ford has been short-cutting for years, very hazardous those Cortinas, Capris and Escorts... Amazed old Mr Ford got away with it!

What I'm getting at (badly) is why, if you're going to start from scratch, would you design a caliper that has what appears to be a design "solution" which could (possibly maybe) jeapordise the function of the caliper? There are plenty of other calipers out there which don't have this potential issue, so I'm wondering what the thinking was behind it.

And yes, I realise it's highly unlikely that Hi Spec started from scratch on the caliper design. In this instance though, it's a shame they took inspiration from a design which is less than optimal, IMO...

And you'll be able to tell the difference in the weights from the drivers seat? ???

It's a matter of a few grammes. Add in the reputation Hi Spec have, I wouldn't touch them with the s***ty end of a really big stick...

Well said blats so the Hi-specs are lighter but the reason for that is that u wait that long for them  they degrade in the ultra-violet  light!!

Buzz :p

You can see plenty of clearance for the pins.

Shouldn't those shocks be swapped side to side so the adjusters are outboard?

Never given it much (any) thought.. Shock could be spun through 180 to achieve the same. I can adjust them easily, either way.

Why do you think it matters?

I'd run them upside down if I could. If only they were the  later Nitrons :)

Yes, as I say, I'd not given it much thought up till now... Been considering it all day since it was mentioned ??? As far as the damper is concerned, it really can't matter, and for the Nitron with a knurled knob, it's as easy to get at either way round. I think they probably ended up that way round cos my Spax were that way round and you need to get a screwdriver on them to adjust  :)
