MG TD TF 1500 - Brake Master Cylinder

Hi Jack,
the cup goes in with the skirt out (see Figs M2 & M4
in workshop manual). Check that it is fully home,you can see through the holes in the tophat.Make sure the holes from reservoir to the bore are clear, I use fuse wire.
Fit a bled nipple to the cylinder outlet and run a tube from it to the filler, top up with fluid and pump until all the air is displaced, The check valve (tophat) will retain the fluid until you refit. This will save you from a lot of grief when you bleed the system.It requires quite a strong push to expel the fluid.
Also check you have only one valve washer (part 12) at the base of the bore, I have come across two cyls with an extra one.
