Hydraulic brake conversion backplate

[Speedex750]

My recollection of these is that you can put the rear back plates on the wrong side which puts the bleed screw in the wrong place. Ditto for the fronts which gives twin trailing shoes, which some deliberately did in the 60's. There's more pictures for how things go together on the (dying) Speedex site. Dennis's picture shows the adjusting screw outwards that needs a hole in the drum, the steel fabricated ones I've seen have a hole in the back plate and the adjuster has to be assembled the wrong way round - but make sure they all adjust in the same direction otherwise you'll get confused! The hard parts of the conversion are a solidly mounted master cylinder/pedal and an effective handbrake lever that looks the part. Make sure the kunifer pipework avoids being flexed.
