Brake line nipples PDWA/Brake cilinder

[MichelvdM]

Hi,

During the restoration of my late 1500 LHD accidentely I have thrown away both of the brake lines between the PDWA and brake cylinder. I should be able to make the brake lines themselves but I am not sure what sizes of nipples are being used. It seems to be a mixture of imperial and metric threads. Can someone help?

Thanks,

Michel

I've taken a look at the old pwda brake lines that i got laying around ..
And it's all 3/8, but just 2 are bigger at the valve , i think it's 1/2 but not sure :/ ..

Did you ask canley's about it ?  

And i've seen you found your way to the forum also  ;)

Hi,

Can it be there is also a difference in PDWA's?
Looking at the one mounted in my car these are the sizes:

Conn. A and C M10
Conn. B and D 7/16 is too small, So I assume it will be 1/2" or M12?
Does anyone know if different threads are being used on a single PDWA

On another PDWA the dimensions seem different

Conn. A and C M10
Conn. B 7/16 is too small
Conn. D 7/16 fits

I am completely lost. Can anybody help out?

Thanks,

Michel

I had to buy in some metric unions when I did the job on my 1978 1500 a few years ago. I don't recall the exact sizes, but they were the only metric unions I've ever needed for a Triumph.

Cheers,
Bill.
