Brake connection nut size...help please Griff or Chim

[alexcurtis]

Hi I am currently taking the body of my 99 Griff.... And nearly got everything done to take it off 4 chassis bolts which I can not do on my own and the 4 brake clutch connections in the engine bay!
Does anyone know what the correct size is please for the nuts they look to be 11 and 13mm but I think they are not metric as spanner is too loose? All help really appreciated as I can then order some brake spanners to hopefully get them off without rounding the flats any more than I have done? Unfortunately sitting them over the manifold has not done them many favours unfortunately!,

Thanks again Alex

AF equivalent to 11 and 13 are 7/16 and 1/2" . 7/16 is slightly bigger than 11mm and 1/2" slightly smaller than 13mm. Most brake pipes are 7/16" AF
