Part 2 - Discs & Drive Flanges


Brake Disc Modifications


The Fiesta caliper conversion uses standard mini brake discs that have been reduced in size from 8.4" to 7.9". I sent my discs to Premier Precision, Norfolk (01263 731555). The service was superb, they only charged me 15 to machine both discs and they had completed the work within 3 days.

This is a picture of the one of the discs as they arrived. I bought mine on eBay from Jonspeed Racing (www.jonspeedracing.co.uk).

The size of the disc before the machining had been carried out, 8.4" (212mm)

The size of the disc after the maching had been carried out by Premier Precision. They now measure 7.9" (200mm) in diameter.


Drive Flange Refurbishment/Modifications

The Fiesta conversion uses a set of drive flanges taken from a MG Metro vented disc setup in order to gain the correct offset to allow the brake disc to sit centrally between the Fiesta cliper. Minor modification is required to remove the wheel locator lugs, as this could foul on certain types of Mini wheels.

Here is a close up of the drive flange showing the wheel locator lugs that need to be removed.

This picture shows the wheel studs removed. I removed them to make grinding the wheel locater lugs easier.

The wheel studs need to hammered out of the drive flange. I used a wheel nut to protect the threads during this process.


Image
I started removing the wheel locater lugs by cutting them off with an angle grinder.

I then carefully ground down the remaining metal using the angle grinder.
