Does anyone know the 'bigger' brake spec of the early 2000 mk1 rally cars? What did they originally fit?

Cheers Darren

I think it involve TR4 brakes but not sure.  Are you using with the very early Mk1 discs and calipers?

I was more thinking the big Girling calipers as fitted to TR2 (?)

The LeMans Spitfires had those and were about the same date.

TR3 had 11 inch brakes compared with TR4 which had about 10 inch - not much different from 2000.  The main thing with Mk1 2000 brakes is that early ones were thinner than later ones.

I would therefore assume that TR3 brakes were used if they were bigger but I would wonder why with TR4, TR5 and 2000 brakes being similar size there would be much to be gained.

One thing I did find as a useful upgrade on the early Mk1 brakes related to the disc itself.  It is thinner than Mk2 and the 'web' where the bolt holes go is much lighter than later Mk1 and mMk2.  My mod to improve this was to simply get a set of Mk2 discs (second hand ones would do but I had some NOS ones) which had a thicker 'web' and machined them to the spec in the Workshop Manual.  Not sure whether it made much improvement but I like to think it did

No, the LeMans Spitfires had/have Girling AR aluminium calipers.

That set up on a 2000 is basically standard Chicane. and you don't want that.

The Chicane used Girling type 16's (TR4-6) fitted to the standard 2000 spider which entails a smaller diameter than standard  brake disc. Every time I change the discs on our Chicane I have to machine down a pair of standard 2000 discs on the lathe.

I have never seen 2000 (or 2.5) spiders with anything other than standard length caliper mounting fingers.

They used standard brake set up but had a range of up-rated pad materials.

The only front brake modifications I have found on works 2000/2.5's are pretty basic, and include removing the disc shield's, solid caliper pistons, and the aforementioned pad material variations.

Thanks Guys for all the info.

I was trying to save weight on the standard MKII caliper which I use on the MK1 rally car and scrutineering currently on some events frown upon wilwood calipers. They are OK with AP on MK1 escorts but not wilwood. AP do a blank caliper but would still need a bracket and I doubt whether it was fitted in period anyway (also hugely expensive). So with mention of something used by early rally 2000s it seemed the only other option.

Although now I hear about Girling AR aluminium calipers... they sound rare and expensive but also lighter than the standard. Very interesting.

Im going to see what the scrutineers think of Wilwoods again on the Rot. As they are a great little caliper.

Not going to fit a saloon.

Mounting lug different dimensions, uses smaller disc, and smaller piston area than a Lockheed caliper.

And VERY expensive!

Could the Willwood name be skimmed off leaving a plain unbranded caliper ?

Laurence


I remember being wrong once before Laurence Cochrane Newtownards Northern Ireland. 1972 Gt6 2600EFI The Mutt. Some original parts fitted, Not many ! Early PI motor overbored to 2.6. Lightened & balanced, ported chambered, cam'd 6-3-1 manifold. Running on DTA engine management system incorperating the PI throttle bodies fitted with electronic injectors and throttle position sensor. 0-60 4.7s & 7000rpm. Seriously annoys owners of modern stuff ! (particularly coz its a heap) 2500 S box with competition 28% od. 3.63 diff with a quaife in it, innit ! Rotoflex based rear but with a swing spring fitted & sliding shafts.(swing spring rotoflex without rotoflex's). Koni's front Spax rear. Hydraulic handbrake. Citroen xantia discs 11,1/4 in dia under Morris Garages 15 in Maestro alloys.

Thats a brilliant idea but the vented discs would probably give it away. The Escort that had them fitted got away with it through initial scrutineering but they were spotted when hey had trouble with the car later in the day.

I remember on I think the Clwyd rally a few years ago an old 40s/50s vehicle went in for scrutineering and was refused because they'd upgraded to discs from drums. Tried all night to convert back but didn't manage it.

So a bit of a pane if you get caught.

They do accept some changes ive already had approved the plastic/Margard rear screen, quarter lights and rear door glazing. Also the inner beams being removed and air vents fitted. (still have the appearance of lights though.)

I think I'll keep bringing the subject up and may get approval.

Cheers
