mike kimmens Posted December 29, 2012 Share Posted December 29, 2012 Anybody got a pair of stag front brake calipers for sale? Hopefully will be getting the rebuilt 2.5 engine back from the reconditioners soon but still running on MK1 2000 brakes with the 3/8" discs. Stag discs and calipers are cheaper than 2500 so I thought I would change to them with the 15" Minilites but need a pair of calipers to recon or exchange.

dazzer Posted December 29, 2012 Share Posted December 29, 2012 MkII calipers would work just as well if they are easier to source Quote Link to comment Share on other sites More sharing options...

Van Posted December 29, 2012 Share Posted December 29, 2012 Try Robsport. I got mine there for my 2.5PI (a few years ago though) and I didn't need to exchange. Quote Link to comment Share on other sites More sharing options...
Andy Borris Posted December 29, 2012 Share Posted December 29, 2012 I'm confused, I know there's a difference between MK 1 and Stag front brakes, but what's the differences between MK2 and Stag?I ask because I'm thinking of doing this very conversion on my MK1, which may have MK2 front brakes (I'm not sure!) and if MK2 and Stag brakes are the same in some way, it may mean less work.I know that MK1's have a thin disc, any other differences?ThanksAndy Quote Link to comment Share on other sites More sharing options...
DJB_Harvey Posted December 29, 2012 Share Posted December 29, 2012 Yes , Mk1's with the thin discs have different hubs as well . Late Mk1 & Mk2's / Stags use the same hubs . Quote Link to comment Share on other sites More sharing options...
Andy Borris Posted December 29, 2012 Share Posted December 29, 2012 So if I change to Stag, I'll have to change the hubs too, if I've still got MK1 brakes?And I understand Stag discs are a larger diameter, does this mean that I need to change the caliper mount too, or does the Stag caliper have longer mounting lugs?Andy Quote Link to comment Share on other sites More sharing options...
DJB_Harvey Posted December 29, 2012 Share Posted December 29, 2012 Yes you will need Mk2 hubs .. Pretty common even new . Stag calipers bolt straight onto all 2000/2500 range . It's only the hubs and splashguards that vary . Quote Link to comment Share on other sites More sharing options...

StagNL Posted January 2, 2013 Share Posted January 2, 2013 I think we've lost a few posts in here too as I'm trying to find the bit where I said I'd measure the hardness of the Stag stub axles I have.There was mention here that the Stag and Saloon axles were the same save for hardening on the Stag items. Checked the R site for part numbers and both are allocated the same number.Checked the NOS Stag axles I received several years ago from a supplier here in NL who dealt exclusively with Stags: both axles have a hardness of around 20-25HRc all over.Checked the old worn ones on spare uprights I have: both are 20-25 all over except the 27.0mm section where the inner bearing fits which was 48-55HRc.My conclusion unless better evidence is supplied: Only the inner bearing race on Stag stub axles was hardened on the originals out of the factory. Probably induction hardening.The (supposed) NOS replacements I have may be Saloon parts. Quote Link to comment Share on other sites More sharing options...

Richard B Posted January 3, 2013 Share Posted January 3, 2013 Presumably this was to handle the extra load on the stub axles from the superior brakes of the Stag? :-/Faster car, higher top speed, heavier use of brakes. Quote Link to comment Share on other sites More sharing options...
James Posted January 3, 2013 Share Posted January 3, 2013 I have some s/hand Stag uprights along with hubs and stub axles that I bought to mock up my new brakes — wonder if they're hardened.Richard— I've never seen a Stag driven like it needs hardened stub axles!

Alex Posted January 3, 2013 Share Posted January 3, 2013 Or in Richards case driven......sorry that was unfair,it was I that left my spitfire in a dry garage New Year's Eve and let someone else drive to the pub. ;D Quote Link to comment Share on other sites More sharing options...
MarkDeTriomphe Posted January 3, 2013 Share Posted January 3, 2013 And to be fair, I do recall Richard's Stag being driven quite hard once - luckily Richard was asleep at the time 8) Quote Link to comment Share on other sites More sharing options...
