Fuzzy, i think that all people are saying is that it is dangerous to dirve a car with a 1430 because it is for one ILLEAGAL, no matter what the logistics of it is. Disc's are required, why, because there is a distinct possiblity to USE the 1430 and it's power to it full potential. For you to go on about how you CAN drive around safely is true, but we all know that people give in to temptation. So suggesting that it is alright to do is as stupid as doing it.
FatMaserati, i would really think seriously about driving your car at all, until you get disc's on it and fix your steering. to do otherwise would be highly dangerous and illeagal. If not for your own saftey then perhaps for the knowledge that you could quite easliy kill someone.
Sorry to bang on, why people would drive around in a car that is illeagal/unsafe is beyond me.

Cheers

Aaron

Just to add support to Fuzzy



Can I beg to differ on this well accepted urban myth.

Now don't get me wrong - I support the NEED for disk brakes on big bore cars but I have extreme difficulty accepting this argument above as it is simply not logical. I will attempt to explain why.....

You have a small bore car fitted with drum brakes by the factory and these are adiquate to do the stopping. You drive around in places where there are traffic lights at around 60kph because your in a built up area and there are speed limits that apply. The drums stop you when requied as stopping from about 60 kpm at a stop light is not that taxing.

Now you put in a big bore motor and you have all that power! but your still driving around where there are traffic lights, and it is still a built up area and it is still a 60kph speed limit and your still braking from around 60kph ......

BUT your have all that power! The urban ledgend would have you believe that naturally your drums will not be able to cope any more - you are a fool - you need disks or you are going to die. Like yeah right, adding CC's has a direct and unavaoidable impact on the braking effort required to arrest the forward motion of the vehicle?????

An so the proposal that you need disks because you have a big bore engine because of the power it has available is really nonsense.

And so to bust the myth. All other factors remaining the same just adding power to the engine bay has no direct effect on braking. Only changes in the way you drive the car will call on different requirments in braking effort.

The Truth .... You need disks with a big bore engine because you WILL USE that power available, you WILL alter your driving style and acellerate a bit faster and for a bit longer. You will be BRAKING FROM HIGHER SPEEDS that require a lot more braking efficiencies than drums can offer.

Cheers
The Myth Busters

Yeah, fair nuff. But I just don't want to be adjusting the drum brakes all the time. I'm still gonna get the 8.4" discs. REAR discs is a bit excessive. It's gonna get fixed, I promised. Until then, I will only drive it when I have to, and trust me, I'm not a hoon. I love my car too much to risk totalling it.

Wow did I open a can of worms or did I not!!!

OK go drive whatever you want with whatever braking system you want. I will not lose sleep over it that is for certain!!!

I didn't mean any disrespect by calling anyone a dick btw... I am sorry I typed that. I was just passionately typing at the time The fact that it is illegal makes me passionate I guess. I am just a law abiding citizen

I might also bring to the table that i ran a fairly powerful 1152 with drums and a booster for a while and it was far from the death machine drums are made out to be.

After all didn't some of the early coopers race with drums?

I'm in no way supporting the use of them in this day and age of disks, i don't like drums as much as the next person, but they reaally are not that bad..

Obviously yes, you should be fitting discs for that motor. End of story. I always love the people who say they want a 1275 without discs, they wont be going faster than they do at the moment etc... then why get a 1275?

Anyway, about your current problems. Check the steering arms as stated, on my car one of the bolts sheered off, making the car suffer badly from torque steer. Wouldn't like to think what could have happened had that not been rectified! With drums I'd mainly suspect maybe the adjustment is out badly, so check that. If it pulls the suspect the front, if it veers to one side, check the back. Check the wheel bearings, ball joints etc, wear or damage here can help cause problems. More so on discs - I had a dodge wheel bearing (didn't realise at the time) and my car pulled hard to one side, then started pulling straight again. We figured it out - because of the free play in the wheel, the brakes would have to take time to readjust (discs remember) so that side would be less effective at braking briefly, but once it had adjusted itself they started braking together. Or something like that....

Steering Rack - is there free play? Ie, can you move the steering wheel left and right without it engaging the actual rack and moving the wheels? Get a helper to hold the driving wheels whilst you move the steering wheel to check. You might need a new steering rack. Don't risk it - it isn't much fun to lose the ability to steer, particularly coupled with brakes that pull to one side!!

Nah, drums just plain suck.

Yes, yes they do.

Great myth busting there Hugh.. i'm fully with you on that one.

Well actualy you didn't call anyone a dick, it was me. And yea it might have been a little rude, but - people seem to view driving as a right with no responsibilities attached. Why would anyone consider driving a 650kg, 90hp hulk of metal that is skiping from lane to lane and shifts a half meter to every which way on small bumps (as per their own description) is a mystery. Why would anyone only consider being caught or wrecking their car when deciding whether to keep driving or fix such a serious problem (which is fairly easy to fix btW), is even more puzzling.

I'm really not having a go mate, but we cant treat cars as bycicles or shopping troleys or something to go to the movies with. Its also a piece of heavy machinery with real, possibility of harm to others and their property. So if its not handling safely its affecting other people too, not just yourself, and its not your decision on whether to continue driving.

Here's a scenario: You're driving at 30kmh, a small bump, you go 60cm to the left, there;s a motorcycle there, or a kid ran out from between parked cars - neither of them guessing that small bumps cause you to veer 60cm to the side. Theyre dead or injured, the car is fine (apart from a small scratch to the debumpered end and a human tooth or nail lodged in between the grille slats). You don;t need the CSI boys to help the coroner find out that your car was falsely registered, and obviously unsafe to drive etc etc. Everybody looses.

I'm sorry if I sound like somebody's mom, and I didn't wanna offend you, but I just feel that driving carries with it a responsibilty, and only not taking this responsibility with desregard, puts you above the ricer, with the 220hp lancer.

Not to my knowledge because all Cooper models were fitted with disks....there was an 850 at Bathurst in 1963 and no doubt other drum brake versions of other Minis competed at other tracks in Oz and around the world....as soon as Minis hit our shores they were racing...

I think Mike McGee claims to be the first to have a shunt in a racing Mini around 1961 at Warwick Farm....

Cool, thank..must have all had at least 7"ers then..well the bigger GTHO's ran drums all round

Maybe they put twin leading shoe drums instead of 997 discs

No, but lots of modified 850s sure did. When the Cooper came out there would have been more 850s than Coopers on the track.

Anto, Cooper 7" discs are not that bad. Convert 997 calipers for 998 pads, fit metal pads and a servo.. they stopped my 998 Clubbie automatic fine, lots of 998 Coopers raced on them in the late 60s. I'll say again, they are NOT THAT BAD, pity they got such bad press...
