Just taken off my rear brake cylinders off my escort axle..
Just measured them .. had a pair of 19mm..
just fitted a pair of BWC 5084 17.8mm - hopefully these will get me through the IVA..
If I find I need more bite on the back - I now have a choice of 19's or 20's
(M16 front - 60/40 Master Cylinder - 17.8 Slaves)
Available sizes:
BWC 5080 20.6mm
BWC 5090 19.0mm
BWC 5084 17.8mm
Ebay:...
