Hi,

 

I am changing the front brakes on my mini, as the standard ones don't seem up to the job any more...

 

I am looking at the minisport alloy 4 pot caiper kits (with the vented discs). My question is will these kits fit under my 12'' wheels?

 

Also will any 8.4'' vented disc fit as i prefer the discs from minispares as they are both drilled and grooved aposed from just grooved as the minisport ones are.

 

Part No:

MSLMS04R

Thanks in advance

Dan

Yup, any minisport or minispares calliper that is designed for the 8.4 inch disc will fit under most 12" wheels that are sold for the Mini.

Thanks for the replys, I had a feeling they would fit but best to be safe,

 

And when i do get the mini out which is not as often as i would like (maybe 1 weekend a month) I do tend to drive it hard, and with the norfolk coast road being FUN the brakes do fade fairly quick...

 

Will post some pics when i get round to it...

In all honesty you don't need 4-pot brakes on a road Mini. They are an expensive non-necessity Even the rally Minis being driven flat out over mountain roads don't have 4-pots and were not available in the days when the Mini was a front line rally car.

What you do need are fully functional standard callipers, top quality discs and effective brake pads. Ideal pads for fast driving are the Mintex 1144, whilst for flat out competition the Mintex 1166 or 1177 are best. The brake fluid may need to be changed for AP600 race/rally fluid to prevent fluid boiling, but that is an extreme case and DOT 4 is normally fine.

If the brakes are fading it is due to poor pad selection and/or poor quality or badly scored discs.

Make sure you have the correct Drive Flanges for the disc/caliper combo, probably easiest to buy a complete kit.

Personally, after running both setups side by side, i notice a difference, and am looking at a second set of 4 pots.

I have got good quality discs/pads on at the moment. Ebc grooved/drilled discs with green stuff pads, and Castro race fluid. They are fine for the first 5ish miles. Both calipers are free/refurbish. I had read some good reviews on the 4 pots from one source and another.

Bin the green stuff pads ... They are too hard for road use. Try mintex or ferodo if you can get them.

I know what people are saying here but I would rather have some thing left in my back pocket.... Well that was my reason for giving kad a load of cash for shiny front brakes.

I do the occasional motorway journey and I would like some spare heat capacity when braking down from high speed.
Also having some grippy tyres is as much a gain. No point deploying a land anchor and having a set of ditch finders on the wheels That are doing all of the work on the between you at the Tarmac?

The largest disc that you can fit inside of your wheels will be of benefit, when it comes to brakes bigger is indeed better

I never suffered real brake fade on my 8.4 standard discs ( yes I've tried it hard enough lol).

Its nt only about spare heat capacity, but also about getting heat in the brakes, cold brakes don't work that good either.

Guess its like all the billet stuff, the special diffs, ... eveyrthing gets strenghtened etc, but do you really need it? proably not.

Like people fitting dry decks to a 998 now... Sigh, I sound old.

On tarmac special stages at night with standard 7.5" 'S' disc set-up and 2-pot standard callipers, running Carbon-Metallic pads and AP600 brake fluid I have actually had the discs glowing a dull red colour, but still had superb brakes.

I really don't know why anyone driving on the normal roads, or on ordinary track days can't make 7.5" or 8.4" discs with standard 2-pot callipers work well at all times.

I believe that 4-pots with vented callipers are only necessary for long-distance racing using sticky slick tyres in the dry on twisty circuits.

The only time I have had brake fade is when testing with poor quality pads, like 'GREEN-stuff' or some other after-market non-branded pads. With the Mintex 1166 or 1177, Ferodo 3000 or Carbon-Metallic pads and good brake fluid there should be ample braking available with plenty in reserve, even absolutely flat-out on twisty and hilly closed alpine roads when driving on full pace notes.
