Sierra rear drum brake cylinders

[davedew]

If you are using the original sierra setup like Gus & Adrian did, then you have to go from a sierra wheel cylinder to a smaller escort one.

Attached is a link to the page on Adrian's website which explains it all.

I think this only happens when using the larger rear drum setup from the 1.8 & 2 ltr cars.
I believe the 1.6 sierra had smaller rear drums and therefore smaller wheel cylinders.

You can always fit the pressure balancing gizmo if like me you have the 1.8cvh.
I'm waiting til it has an MOT before deciding on this option

Hi AJ apparently you are not allowed to use the brake proportionating valve for the IVA, which I find rather odd since it was part of the original vehicle.

DOOOH!

Mine and a couple of others passed iva fine with the larger drums

All my brakes were totally new and well beddded in
