Brakes - How They Work

This time we’re going to look at just how brakes do what they do, and ways to improve them. Without a doubt the most important point to get sorted at the outset is just what makes brakes do their thing - FRICTION. The sole purpose of the brake set-up on any vehicle .....

What you actually need for the disc/drum conversion is pretty straightforward. Disconnect the steering arms, top and bottom swivel-pins, CV joint, and flexible brake pipes at the subframe - that’s it. There are, however, a number of ancillaries to consider.

Basics

Basics Fitting discs designed for the Mini is easy enough. Just make sure you use CV gaiters for the disc-brake set-up - these have a different bellows shape to stop the gaiter rubbing the inside of the hub. The drum type will rub, then split, shedding grease all over the place. Moly grease is mighty mucky stuff to deal with and doesn't assist braking at all! A tip for racers - to stop the gaiters over-expanding when getting very hot and imitating the aforementioned, put either a decent sized split pin or (my favorite) a piece of very small bore pipe - as in the type supplied with WD40 aerosols, etc. - under the retaining strap on the drive shaft. This allows air to escape and return,

Brakes - Fundamental Considerations

When looking to increase their cars performance, most folks immediately turn to considering higher engine power outputs. Because of this pre-occupation brakes tend to slide down the improvements priority list. However, they are far more important - being able to accelerate at warp speed to hyper-space in the twinkling of an eye is all very well, but disastrous if you can’t stop. You will make a very big hole in the scenery, and possibly end up wearing an wooden over-coat. Getting the braking system sorted out can help to make the car quicker, as you will be able to more confidently, therefore maximising speed in any given situation. Being one of those ‘sciences’ used in the automotive industry I hope to shed some light on the subject as it's another of those where many questions from confused and mislead folks that clog up my e-mail board. The advent of the Metro, and the brakes used on it has spawned a lot of activity in this direction. It was soon discovered that they could b

You can only use the MS72 adjustable brake regulator/bias valve with a front/rear split system. Definitely NOT the diagonal split type (for identification see 'Brakes - Rear brake bias adjustment'). These should have been 'X-ed' at birth. Makes the car handle very interestingly when the system only operates the diagonally opposed brakes. Scary stuff. Almost as much fun as when the rears only work on a front/rear split set-up - particularly as the PDWA is built into the master cylinder, and it still has to go through the FAM7821 pressure regulator valve! Damn near no braking on the rear. Either way - split system brakes are grossly inefficient when only using half the system as they are designed to do when a failure in the other half occurs. Quite frightening. To install the MS72 into a front/rear split system, it needs fitting into the rear feed line. Determining which this is can prove difficult if the system has already been tampered with or new replacement components fitted. Nam

Engine - 998 Tuning, Bolt-ons

The 998cc engine is a very robust and tunable unit. It is also the most common engine found in standard Minis. See bottom for useful part numbers Terminology: MSC/MM - Mini Spares Centre/Mini Mania ID - Inside Diameter OD - Outside Diameter BBU - Big Bore Unit (refers to all 1275cc-based units) SBU - Small Bore Unit (refers to all sub-1275cc units, here the 998) BHP - Brake Horse Power LCB - Long Centre Branch Despite the lure of the much-advertised 1380cc alternatives, many simply want to get a little more from what they have at reasonable outlay. The single biggest restriction on any standard Mini is the 'breathing apparatus' - anything that is connected to the induction and exhaust systems. The standard exhaust being the biggest culprit - it is desperately restrictive in the name of noise suppression and cheapness of manufacture. Oddly enough it also increases fuel consumption when tested over a better designed, fre

Air filtration - K&N Air cleaner test.

In the forefront of Mini tuning, improving the over-all breathing capability of the very asthmatic A-series the air filter set-up is one that sees priority attention. All the widely available (and widely varying) stage one tuning kits include at the very least a replacement - and hopefully - high-flow air filter element to fit into the standard plastic case,

In the past few years (well, must be nearly 6 years by now!) since I got involved with writing for the specialist Mini Magazines I have been continually fighting with the problem of limited space. This has limited what I have been able to cover, both in subjects and in details. Up until recently (say the past year or so) I have been covering fairly broad topics in a fairly broad terms and detail. Basically trying to cover perhaps the most popular areas dabbled in by the Mini owning masses.

The 998cc engine is a very robust and tunable unit. It is also the most common engine found in standard Minis. Despite the lure of the much-advertised 1380cc alternatives, many simply want to get a little more from what they have at reasonable outlay.

Terminology:
MSC/MM - Mini Spares Centre/Mini Mania
BBU - Big Bore Unit (refers to all 1275cc-based units)
SBU - Small Bore Unit (refers to all sub-1275cc units, here the 998)
BHP - Brake Horse Power
CR - Compression Ratio

To improve engine out-put, you need to increase the engine's 'breathing' ability. The stage one kit deals with all the easily bolted-on external parts, and represents the best increase for investment. From here on in the power increases will cost commensurately more money.

For use when converting cars which already have hubs fitted that hold calipers except 997/998 Cooper which will also require larger Constant velocity joints and Timken bearings, If you have brake shoe front drum brakes a kit C-AJJ4029A is available which contains all parts required..

The contents of this kit ...

These calipers are intended for use on 10”wheels with 7.5”diameter solid brake discs.

The kit contains:-

2 calipers, one right and one left hand. Please ensure that they are installed correctly with the bleed screws in the vertical position (i.e. at the top)
4 longer hub fixing bolts(53K1049)
4 bolt washers(21017Z
4 round spacers (AN1380) which go between hub and caliper where the fixing bolts locate. Bolts and spacers not required when fitting to vented discs
1 set of brake pad split pins (GBK1025) BUT NO BRAKE PADS.

Mini Production dates

We have tried to get together as complete list as possible to show all the models made from 1985 onwards, hopefully this will help identify those cars that have been modified over the years. If you have any information that you know is correct or anything that you think is not right please let us know.

Black Friday has arrived at Mini Spares and it’s bigger and better than ever!

Mini Spares are pleased to announce that their popular Black Friday event is back and is bigger than ever with an amazing 4,500 products being discounted!

In 1988, a humble 1973 Mini 1000 was minding its own business somewhere in London, when along came a young Mini freak called Jason King, who wanted to change it for ever, and make it famous.

Jason persuaded the owner to take £450 for the car, and then proceeded to throw £12,000 worth of presents at it for the next 3 years. Every minute of Jason’s spare time was spent working on his new car and every minute of his working time was spent looking for spares.

“PLAQUETTES DE FREINS” (BRAKE PADS)

One commonly asked question is in reference to brake pad types best to use, expected lift and characteristics etc. Especially in reference to race applications, so I shall try and outline the pad types we keep and their “essentials”.
With all things there is always a compromising area, and brake pads are no exception. Main usage or priority should be the deciding factor, the shortcomings at either end of the spectrum should be tolerated and given due consideration.
A major part of braking done on road cars is around town, or short distance, multi stops. The next is braking from cruising speeds, be it when encountering traffic build up, or slowing on off ramps. The brakes are rarely used in severe and continuo...

“PLAQUETTES DE FREINS” (BRAKE PADS)

Mini Spares Centre News For some reason, discs (brake rotors for the foreigners amongst us!) for the 'S'/early GT have become more and more difficult to come by. Well, actually, that is not totally accurate. I guess that statement should read "decent quality discs". I know there is a supply of, erm, EEC country manufactured discs purporting to be high quality, but they are extortionately expensive, and are only totally (?) effective...

Within a week of returning to our shores, the Mini Spares Monte Mini attended it's first press engagement with Mini World magazine. Mini World journalists are avid readers of Mini Tech News and give us flattering reviews each time they receive a new issue. Crisp folding stuff is not even needed.

8-Port Power The Arden 8-port cylinder head was designed over 25 years ago, yet it remains one of the most powerful and effective heads available for the Mini A-Series engine today. Designed with racing in mind, the alloy Arden 8-port head was conceived by Jim Whitehouse in 1966/67 to take full advantage of a change in Group 2 regulations, which allowed more freedom in cylinder head design.

8-Port CCC Magazine reprint Mike Askew is the editor of Mini World magazine, and anyone who writes so many nice things about our 8-Port car must surely be a jolly nice chap. His story in Cars and Car Conversions is reproduced,with their kind permission, below.
