Earlier this week I got the final report from Steffen Madsen. He declared that he was satisfied with the conversion from Girling discs to Alfa Romeo drums. Only problem is that I will have to wait until spring to really test it myself.
For adjustment he fabricated a more precise adjustment tool (the rough tool was made from cardboard, remember) that will show if the brake shoes are true and perpendicular. I asked if it was difficult to do adjustments, because I had heard so much about the difficulties with these 3-shoe systems.
The comment: "The car runs fine, although it needs a trim of the jets! And clutch! And gearbox! And differential ... But aparently it brakes fine, it needs a good boot before it's really worn into a perfect fit. It pulls a bit to the left - but only sometimes. I think it will fix itself, when things have been beaded in. (Did it pull left with the disc brakes?) The brakes are very easy to adjust, you will learn quickly. Otherwise you will need a mecahnic to go with you and do the trimming between races ;) I havn't braked really hard yet, but I think it works fine. It certainly brakes harder front than rear, I can see that on the brake stand. I think the biggest problem will be heat build-up! But that can be helped with some cooling hoses - and maybe by using the accelerator more than the brake pedal."
