Koen's 86 - every drive a new issue

[Koen]

Made some progress creating the twin brake master cylinder for the grey car.

Two options to make this in the homologation papers

I decided to keep the cilinders in the engine compartment. The green car has a similar setup, so I could copy some dimensions from that car.

Removed all the old bits from the car to have some room to build something new. I've welded a plate on the bulkhead with the correct holes for the AP cilinders and to add some stiffness (the bulkhead flexes quite a bit when braking)


As you can see it's in practically the same position as the original. It fits in the "box" in the bulkhead which also helps to prevent flexing.


I've made a box that screws to the bulkhead using the bolt holes of the AP cilinders. Its welded to a cut up original bracket of the brake pedal which contains the brake light switch and the top mounting hole.

The tube that holds the balancebar will be welded directly in the original brake pedal, but I forgot to order that . Then the whole assembly should work and fit in the same position as original

The top one is the full original assembly, bottom one the replacement (+ balance bar and the reservoirs)
