Having just washed both the 7, & the 8, [8 with rear discs], I am
glad the 7 has drums.

You spend a lot less time, down on your knees, when you don't have
to get pad dust off the back wheels. Besides, who wants to stop,
anyway.

Thanks for the support there Cobber. It's not that I don't want my
car to stop, really, it's just mu knees don't like getting down to
that brake dust.

Quite a few of those brilliant old time designers had a lot of
trouble getting interested in stopping.

And Peter, I think you should have very good brakes, & apply them
often

Does anyone have any experience of fitting standard front brakes at the rear end? Would this route be simpler than some of the others?

I've thought the same Hasbeen[;)]

First, thanks for all in sharing the info. I shall store this all away in case I decide to do the upgrade. For now I need to concentrate on getting the fronts to live longer at the track. I still have the stock TR8 rear drums which after some research appear to be fitted with the 4 speed wheel cyls from factory. I have also eliminated the proportioning valve and fitted an adjustable bias to the rear. At the track, I was getting the rears locking and had to back off the valve. Was a very tense moment at the end of the frt straight!![:0] I think the instructor wanted to jump out of the car.

Hi TRPhil,
One big draw back fitting front set up to the rear, lack of a seperate handbrake, unless you use a set up similar to TR8Coupe with the parking brake caliper.

Wow John, that axle is looking really good, you've obviously put in a lot of work, plus I'm jealous of your work bench!! I wish I had one big/strong enough to put an axle on it!!

Anyway, I'm just wondering (for a future project) what car the hand brake cables are from ? They look like 2 separate ones that I suppose join at some point, with one cable going to the handbrake itself ?

Thanks, Dave

I was aware of that limitation (and had been thinking along the lines of using something from an old Citroen e.g. CX where the handbrake set-up uses separate calipers acting on the front discs) but handbrake asside wouln't this be a fairly simple install?

Hi Dave,
The parking brake cables are from a MK4 VW Golf!!(Audi calipers used) Turned up on Fleabay 99 pence each! thought look about right emailed the guy and asked him to measure inner and outer cable lenths and thought if they were not suitable must be woth that again to relist them!!
Going to jion them with a peice of steel with 3 hole in it, 2 which the cables will pass through on the outside of the steel with 'cable bullets' preventing the cable being pulled back through, then the centre hole will have a threaded adjuster attached to the conventional handbrake linkage instead of the standard cable SIMPLE!!!!
Will post some pictures when done if intrested (or start a Blog with the full run down how i have done this [?] )
cheers John

No Beans, we are in total agreement, I was only joking. I too, want
excelent brakes, in mint condition on my cars. There was 180 man
hours put into the brakes on my F2 Brabham, to get the best braking,
along with no drag, to use up its small horse power.

Still, I can detect no improvement in the braking capacity of the 8
since I fitted the discs to its rear end. Of course, as a white
haired, elderly gentleman, no longer competing, who scrupulously
observes the speed limit, no matter how low our Bl@@dy stupid
##$@%^^$@#!!*# politicians set the thing, [Ha] I am unlikely to test
the rear drums to the limit.

In defence of drum brakes however, I will claim to having the best
brakes in the Bathurst 100, in 1966. This race was second only to
the Australian GP in importance in open wheeler racing in Oz back
then. It was a race for F1, F2, & selected faster FJs, & other
racing cars. The FJ had only a Cosworth Ford 105E, 1100cc pushrod
engine, but was getting over 140 MPH down conrod.

My Lotus 20 Formula Junior was 6 years old, & had Alfin drums all
round, very well set up for minimum drag, & maximum braking. From
start to finish of the race, I could outbrake all the late model
F1s, & F2s, with their discs all round. At the bottom of conrod, [no
chase to slow you down back then], I could brake at least 80 yards
later than the F2s. I could slipstream them down the straight, &
pass them into Murrays corner. The fact that the car weighed only
860 LBS probably helped.

It is a matter of record, that I finished third outright in the
race. It would have been pretty hard to do that, if my brakes had
not been good, I was giving them 400cc in engine capacity.
