After a near rediculus amount of research i decided on the sierra cosworth rear discs and calipers. They should be perfectly matched to the front and the balance should be pretty close for the weightdistribution of the car (there is a bias valve just in case though)

Chipped away at the brakes again today (not literally of course)

I removed the "hand brake lever ends" from the old calipers and welded them onto the new calipers, and thats about it for today, I'm out of money and now completely out of cutting discs, they're all down to the metal :(

I could run your brake figures through my calculator if you'd like...

Thanks Woody, I think it might be something like what I've made though.  I made a spread sheet with the piston size, the pad height and the disc diameter all considered to give a front back brake bias value, then compared that to the vehicle weight distribution.  I did this for a number of cars and tried to get the Scim as close as I could to an E36 M3 (50-50 weight balance).  All the calcs are great but I don't yet know the balance of the scim, I've put the battery in the back and all the pumps along with a hefty LPG tank, and a heavier Diff, and the engine is much lighter than the old Essex so I'm hoping its approaching 50-50. 

Does your calculator do about the same thing?


a little geeky right ;)

yes, sort of.

it goes on to put out the adhesion curves required by the EU for type-approval and to postulate when lock-up will occur at each end, that sort of stuff.

have you started with pedal weight ?

OOOOooooo sounds a lot better than mine, but I guess it must require the car's weight distribution which I don't know yet. 

Did I start with what??  I'm using the standard master cylinder and servo, as the piston sizes are just a bit bigger than the originals.  so I should get slightly more braking effort for the same pedal effort if that's what you mean???

Got a tiny bit done yesterday afternoon, and I'm back at it again today :)

I welded on a little breather pipe so I can attach a hose to go into the car, this way it hopefully won't be sucking in water and dirt. 


And one of my very least favorite jobs in the world, cleaning up the calipers ready for paint.


Its all taking a very long time at the mo and I'm not getting a great deal to show for it, I can't wait to get to the "putting it all together" stage, it seems a lot more rewarding than what I'm up to at the mo.

I spent a lot of yesterday swapping one of the front hubs ans the new PCD was all wrong, I'd got another one done correctly, but the old disc mount on the back needed turning off to get the ford studs in, and the old bearings needed replaceing with the new ones that were in the duff hub.  got that all painted and fitted then went about renewing the seals in the front calipers.  Got them fitted to take a sneeky peaky at how they would look, then ran out of time :(





The 282mm discs kind of look a bit lost in the 16" wheels, but they're the right ones to match the rears, I'll stick with them for now and see if they fade when I finally get the car on track (as in track day :) )

More to come (although it'll mainly be cleaning parts)

Good to see you are making steady progress.

Many jobs are 80% of the work being the preparation and 20% the enjoyable, putting together stage. But once it is finished the results of doing the 80% well make it worth it.

Yeah it can't be too far off now, I've got a uni buddy coming over soon, we'll do a full weekend on it, with the two of us, we should get loads done.

Got the brake hose mounts finished off, the axle cleaned down with petrol and painted.  Painted one side of the brake brackets too.

Nice lathe - Colchester Student?

Nicely painted axle too - what paint did you use? I'm currently trying to decide if I should just press the bushes out, clean up and then paint the Jag donor suspension bits for my project, or have them blasted and epoxy coated instead..

A keen eye :) its the triumph though. Its over 50 years old and still going well. The paint is rustolian or something like that its similar to hammerite, its not much cop really, the paint starts coming off a couple of years, it wants blasting and priming really. You should get them done proper, i might do in a couple of years when i know it all works.

I felt like we made major steps forward this weekend.  An old friend came round and we had a good long time working on it at the weekend.  We got all of the rear axle assembled, with all the painted brakes and new hoses, and mounted the speed sensor behind the wheel again. 







I'm really pleased I went for blue, I think its a much nicer blue than in the three photos I edited.  BUT and its a big BUT it looks awful with the yellow pads :(

Might slap some more blue on the pads, not sure yet. 

The handbrake cable took a while to get right and to get the routing right so it wouldn't be too near the exhaust. 

Then spend most of saturday night making hoses to go to the rear and generally mounting things in the car.  I'm really pleased with how the routing of cables and the brake hose looks going about the transmission tunnel. 




Then we lowered it onto its wheels for the first time (maybe??) but certainly the first time with all the brakes done.  I loved seeing it looking low ans sporty again after having been sat high on axle stands for so long.  We rolled it back a bit so we could test the Lambda gauge and mess with the ECU settings again without the smoke filling garage (sorry this is yet another photo of the car not really looking that different :) )



And here's my friend and I looking very pleased with progress (I'm the taller one)


The list of things left to do is getting short!  Here it is:

To Do

LPG line
Make Rad cover/inlet tubing
Make Hoop mounts
Paint Pads
Fill and Bleed Brake system
Change Cooler over
Get hoop made
Fit all the fuel gubbins and secure hoses
Fit Propshaft
Fix Shock bushes/ get some better ones

Fit Seats
Rivnut kick plates
Fit New seat belts
Rewire front lights (reduce loom)
Sort Headlights HID/Butcher a modern?
Draft stoppers for door hinger area
Block speaker holes in doors
fog light bulb for rear (red)
Fit polycarbonate rear quaters
Polycarb boot hatch (and stop rattle)
De Chrome some bits???
Fix Mirror glass
Sort Spring/Damper Rates
Smarten up the paint
