I've just opened the packages for my new master and slave cylinders (justpurchased from Landyparts for a series 3 as other threads on here) and the pipe connections are different.
The master cylinder outlet is 3/16" (same as the brake system)
The slave inlet is 1/4"
I could pipe up with 3/16" (aeroquipe braided) and use a bango bolt at the slave end. Would this give enough fluid to operate the clutch or do I need to exchange the master cylinder for a one with a 1/4" outlet and go with 1/4" hose/pipe)

I've been running a landy master cylinder for years using 3/16 pipe with no problem.

If you push the clutch pedal to the floor you must displace a set amount of fluid regardless of pipe size.

However, if that pipe is smaller there is a good chance you will make the clutch (maybe not noticeably) heavier.

Think of it like a bicycle pump, easy to pump if connected to nothing but put your finger over the end creating higher resistance (smaller pipe) and its harder to pump.

Well that's my theory anyway scratchchin

Manufacturers, not just TVR must use larger pipe for a reason ?

The brass fitting that goes into the Landy master cylinder is available for both 3/16 and 1/4 pipe. I did however struggle to get the 1/4 pipe fitting and my local Landy centre said 3/16 would be fine, they were right.

I've got 3/16 pipe on my clutch (recently fitted) works perfectly, but yes it does make it slightly heavier.

Cheers.....Tony..

I made some enquiries and 3/16 is fine - I will need a 1/4 banjo bolt at the slave end - I'm running it all in aeroquip
