Evolution-VII

Hello guys,

I've been searching for a while about this and I couldn't figure out what to do.

I'm building a trackday car based in a 1995 Ford Fiesta Mk3.5 engine swaped to Duratec 2.0.

The original engine (endura 1.3) got fire and the entire engine bay was compromised.
The original brake lines, fuel line, master cylinder and so on is gone.

In order to adapt some hydraulic system for the IB5+ gearbox, I'm thinking about going to some Pedal Assembly and I was thinking if I can make everything with braided hoses (aeroquip), from the reservoir to the master cylinders and from teh master cylinders to the brake calipers.

What do you guys recomend?

I've found a very interesting thread in the Bimmer Forum:

There are a very divergent opinions about it.

But this was the final word:
"I would be happy to quote you. Just select the end fittings and line length.

I know that there are lots of builders that run full cars with SS braided line. I was talking with our AP engineer about this and he was vehemently against it. His stand was there is inherent flex in the line, even if the driver doesn't necessarily feel it. The less compliance in the brake system, the better the feel and response. This is a guy that has 25+ years with AP and supported just about every professional racing series on the planet. I would run hard line as far as you can and limit the flex line to places where necessary."

I will probably go with hard brake lines.

Weigh up the cost first!
I've just done a clutch and F & R brakes entirely in (mostly alloy) Goodridge. It gets incredibly expensive if you do it properly, with bulkhead fittings etc. Hard lines and plated fittings cost a fraction of the price by comparison.
I can understand the perspective of the AP engineer, but the only thing I would add is that I sense the braided lines (being flexible) are more likely to survive a big impact intact?

Hardlines (copper and fittings) Ł28, braided lines anything from Ł150+

I have always thought hardlines are best because if you press the brake the pressure built up has to go somewhere (the easiest route) which in hard lines is the calipers but if you run flex lines the same cannot be said as flex lines as name says flex and can expand taking up the pressure hard lines cannot so there for forces fluid /pressure to calipers
