I would like to replace the O-rings on the brake fluid res. seeping between the res and the master cyl. I would rather not buy the whole kit when it seems only to be a seal problem. Any one know the sizes? Perhaps I will complile a sheet with all the o-rings and various aftermarket parts that can take the place landrover parts and pieces like the BMW screw that fits the plastic bleeder on the radiator.

That being said Ill start a new thread for that.

 

Here you go.

Turns out that Audi used the same master cylinder in some of its cars. They're not cheap ($38+ for both) but less than buying the full rebuild kit.
