Can report successful completion of this upgrade, slowed by needing to replace rear cylinders whose nipples snapped off (again).. Great Varley development work, thanks chaps.

Works fine with rear drums -locks up fronts first. I have Punto ELX front discs and callipers fitted and this feels like a better upgrade than that was.

Pedal travel is much shorter, power is immediate and as usual if I had to fo the job again it would be much quicker now knowing what's involved.

A couple of minor observations for others considering this:

The Lexus master cylinder has a couple of clip mounts cast into it and I used the handy front one to mount the tee piece splitting to the fronts.

Have not yet managed to get the low fluid warning sensor to work again but that looks possible with the right Lexus electrical plug. The reservoir has a lower outlet on the side which I plugged with a bolt and some glue.

My spare wheel at 14" didn't fit under the bonnet anyway but if you're thinking of doing this the larger vacuum cylinder does stick up further and may stop the spare fitting but I haven't checked this. The rear pressure limiting valve also needed to move for the same reason.

As Steve said - this is well worthwhile, cheap and fairly easy. Very glad I took their advice.

As a lowly pandaneer. I believe it does as the master cylinders. Are not linked by a mechanical means. Fluid chamber. So the larger rear chamber created pressure when the front brakes. Start to resist the flow. The second chamber moves push ing the drums. This prevents the rearsxel sluing out. But it could also the rear restriction valve holds off the pressure until the front is resisting flow. I think.

From memory,if I read the post correctly, there IS a mechanical link inside the master cylinder. The idea of dual circuit is so if one brake circuit fails(burst brake pipe ect) you can stop the car using the other circuit,be it with half braking force or there abouts. If there was no mechanical link,

Ok. Next up grade move back rear axel. 25 mm to miss those wheel arch’s. Then onto the. (Triangulating flexi swivel thingies ) View attachment 195526
