Saloon Brakes

[list...@liberator-systems.co.uk]

 I am in the process of overhauling brakes on saloon.  I read on the QOC web site that over the years there were different rear setups (G valve, cylinders) recommended by QSC via the build manual and subsequent technical bulletins.  Does naybody have copy of that info?

Saloon is a late 1991 factory build and currently has no G valve fitted to rear brakes - my guess is  this is how it was built looking at condition. The current rear axle / brakes look like a standard Fiesta Mk2 (30mm wide shoes). Haynes states XR2 had wider 38mm shoes but parts suppliers all seem to list XR2 shoes at 30/32mm width so not clear if   XR2 did actually use different wider shoes or drums. I have a spare complete rear axle from an XR2 race car so will check that when I can un bury it from the back of the garage (but it may well not be an orginal XR2 axle).

Before I took the car off the road for rebuild the brake performance was truly bad - even allowing for the fact it is old school it should have eperformed much better given the lower. weight of saloon versus Fiesta. As I work my way to the front of car I guess front brakes & servo will also need attention / upgrade (currently looks like XR2 vented disc setup).

So what setups can be recommened for the rear? Use G valve? Use different type of adjustable bias valve? Rear cylinder size mm? Shoe width size standard/XR2?
