The Landy has a -4 hydraulic clutch line, except at the master cylinder which has an adaptor on it's outlet, which takes it from -3 (3/8unf) to -4 (4 being larger). With the hose, it's got 5 joints or 2.5 times the chance to leak! I'd like to replace it with a braided hose, a 3/8 unf fitting at each end, this means -3 hose throughout it's whole length, instead of a tiny section of -3 then -4 for most of the hose/pipe. What difference will all -3 hose make? Harder or softer on the pedal, more travel or less? Pic shows present layout.  |

Possibly harder pedal....
But since both cylinders remain the same size I can't see there being much change otherwise beyond a slight decrease in overall fluid capacity

in theory it can restrict the flow in cold weather and cause a heavier clutch when you depress it and slow the response when you let it up, in practice I've done it and never noticed a difference and many modern cars have the smaller clutch pipe.

Been looking at this further and (as far as I can tell) because I've got a 3/8 unf thread in the master cylinder and a 7/16 unf thread in the slave, an adaptor has to go on one end!
So I think I'll stick with the Land Rover design and have the adaptor at the master cylinder end, I can easily see if it leaks and the pedal pressure stays the same. This means it's -4 hose system.
I'm sure there's a reason Land Rover did it this way, even if it was just "that's what was lying around the factory" when they built the things!
Unless you know a way around it?!

The pipe size is irrelevant unless it is small enough to restrict flow. You will not get close to restricting flow with the hose sizes quoted.

The bigger pipe seemed to be something they all did in the 60's, I wonder if it was a throwback to older fluids, certainly won't be an issue with DOT4.

It's weird that it's effectively a big pipe with a small nozzle at it's entry point, either have one size or the other! It's because of the parent companies approach to engineering in that they went their own way in some areas. Well engineered but different, to set themselves apart from others. |
