I bought an Eesibleed way back when I needed to dry fill the MGB system. It came with a vast array of master cylinder caps and the only one which was damaged was the MGB cap.............
So I had to do a DW improvisation, and modified a standard cap. But I never felt happy using it. It uses air pressure from the spare wheel, but even with 3 - 5 psi, a small leak could spray fluid everywhere, which is not good. So I favour the old fashioned way.
I do need a new tube though.
Dave,
I agree about 'easibleed' This Draper thing was just a proprietary version of what we have all set up- no air pressure via spare wheel.
Re tube- what's wrong with traditional method of acquisition? Blag it from a school/college chem lab!
