Converting live axle to disks
Hi all,
I think that my car has and English axle and I wanted to convert it to disks from drums. My questions are what do I need and how do I correctly
identify the axle?

Easiest way is to contact Rally Design and buy a kit of parts off the shelf.

Fiesta solid front discs fit on the rear with the drum backplates removed. You'll need some callipers like the VW or Pug/Citroen ones and some
brackets either welded on or bolted to the half shaft bearing plate.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I'd have to ask - why?
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

I have to agree - why? - the conversion to discs just makes the assembly heavier and you end up with a sytem that will be overbraked and need to be
restricted by a bias valve etc.
Only worth while if on a heavy car with poor brakes as standard that you intend to make much quicker.
If you want to upgrade - go for drilling the back plates to add a bit of extra cooling and new grooved drums.

Just use Escort Mk3 1980-86 front non-vented discs very cheap for www.buypartsby.co.uk (less than 6 quide + vat + p&p
Rear Calipers Rover 216 or 416 or VW Golf are about ideal.

In the 1970s they were the only discs that fitted straight over a 4.25" pcd hub but things a have moved on a lot since then, just about any
80s-200 Ford Sierra or Escort disc can be used.

True but the real benefit from rear disc on a Locost is they respond to pedal presure in a similar fashion to the front discs unlike drums which
have a different friction/pressure curve.

New drums are £35 each + backplate + cylinder. If you can get the Golf or Pug alloy calliper with a small disk I don't think there's that
much of a weight penalty, plus disks give a firmer pedal as mentioned.

I've yet to find any disc that will fit straight on, most need the half shaft flange reducing in diameter to allow the disc to fit, easy job
though, two minutes on a lathe. I have a pair of brackets for the Citroen/ Pug calipers to suit using the Fiesta/Escort discs if you want them,
straight bolt on job.
DO NOT PUT ON KNOB OR BOLLOCKS!

same here Gazza, always had to turn a tad off the halfshaft flanges, pretty std mod.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

I turned the discs rather than the halfshafts as I worked on the premise that if I ever broke a halfshaft it would be easier to scounge one if it
didn't have to be already machined.
