Hi guys needing some advice on brakes, I’m wanting to sort out the front brakes on my Hc estate but thinking of upgrading as I want to put a different more powerful engine in it.
Any ideas on the brakes it’s a 1256 Hc estate

I think it depends on how much you want to machine and modify, as far as I know you can fit OHC discs and calipers for a bigger disc, then change to m16 calipers for more force, but you may need to beef up the crossmember depending on your engine weight

Just be aware that any 'major' alterations will change the way Mr DVLA will look at the tax and MOT situations!!

There's a thread on here somewhere about using those Renault front discs.
There was someone in the club Facebook group doing a serious upgrade kit sometime last year, I think.

You need the OHC uprights to fit the Renault discs. Unless you increase the diameter of the disc or the contact area of the pads all adding vented discs will do is do reduce the tendency for brake fade. Fade is something you don't really have to worry about on a road car the weight of a Viva.
The standard Viva brakes are quite good if they are in good condition, fitting good quality pads makes a vast difference to mediocre feeling brakes. Check out the various compounds available for Minis, assuming you have Lockheed calipers.
There are 4 pot caliper upgrades available for Minis which will fit the OHV uprights and work with standard 8" discs. These will add extra pad surface area and therefore increase stopping power.
I'll believe Jodi Hunns of the FB page makes various brake upgrade kits which fit OHV and OHV uprights.
