Am doing this to GF's Mini, but not using Vented Discs.

Have been advised all i need is the Metro - Mini Braided Hose, ERA Bolts and Metro Pads.

And thats it, probably the cheapest way to 4 Pot brakes by far!

Hello there,
I recently bought a pair of 4pot calipers that I'm going to refurbish (by the way, hard job?).
I've read somewhere that 4 pots could fit under 10ers? is that right? I also read in another place that it could but involved drilling other mounting points. How hard/tricky could that be?
Thank you all for your help,

Marc

yeah, they certainly dont fit under 10's as a rule! There is a FAQ i believe on grinding them to fit under certain 10's on this site. As for refurbing...it can be a pain getting old pistons out etc but certainly do-able. The one comment i have is on cost.....per caliper you are looking at 8 a pot, thats 32 plus 8ish for seals and a few more quid for bleed nipples. then maybe a wire wheel drill bit and some paint. I picked up a professionally refurbed one from ebay for less than 30 and one from PMA motor factors for less than 60.

I like doing things myself but some things aren't worth it. You shouldnt need to drill new mounting points, although i did see some once but cant remember the reason they had to be done? :thumbsup:

heres the full list of what youll need for the conversion, just done it myself and ill say a vast improvement!!!

2x 4pot calipers

2x brake discs

1x set of pads

2x metro drive flanges + 8 x bolts (disc to flange) may need to drill the holes to 10mm to fit the bolts through!(no big deal)

4x metro caliper bolts (ERA - although dont think available anymore)

1x braided hose conversion kit

1x pad retaining kit



fitting is mainly using a 14mm socket and also a 17mm socket, unsure of the hose spanner sizes atm!

basically whip the old kit off cut the caliper off the hose and unbolt from the subframe inside the inner wing 22mm i believe(dont count on it)

remove disc+ flange and tidy the area up maybe paint for extra life of the car!

then bolt the metro flange too the metro disc 42lB i think 17mm socket

slide the disc on hub.

install the hose kit and connect too the caliper use the join pipe to the second piston going top to bottom so not to trap any air in the loop!

mount the caliper too the hub with the era bolts(longer + stronger than std bolts for the extra force! unsure of torque

install pads + retaining kit.....then

BLEEDING THE CALIPER!

basically, bleed the lowest nipple furthest away from the car (this takes the longest 1-2 mins)

then the nipple on the other side at the bottom

then the top nipple (these take just a few seconds)

obviously you need to do the whole car not just these calipers!


then brace yourself for the first drive! LOL

Some of the metro drive flanges have locating lugs on them you will need to remove these.
you can grind them off or machine them on a lathe

Do you have to grind the 4 ligs off each hub to fit particular wheels or is it required for all types of wheel (make, size and offset)?

The lugs were to locate Metro wheels, any other wheel apart from these will require the removal of these lugs. The flanges we make have these removed already

On the topic of removing the lugs, how much will it cost to get them removed at an enginers using a lathe?

Or is using a grinder ok?

Has anyone doing this conversion bothered to refit the disc sheild (I think it's maybe referred to as "Dust Shield") or just throw them away as done with standard Mini?
