Question for AdrianH on brake setup
bigpig - 13/12/09 at 12:29 PM

Hi,
I saw your earlier postings on brakes, how did you get around the problem with your IVA brake balance failures?

I know you can't use a propotioning valve now, did you use smaller rear drum slaves or something?

I'm using Sierra 2.0 drums rear.

This from another well known forum

Front are Sierra disks from 1.8 CVH and rear are 9 inch drums again from same car.

Only change after first fail was to reduce the rear cylinder from 22.22mm bore to 19.05 mm bore. Escort cylinders I believe.

I have no numbers from the test, can only hope they manage to send them on I would be interested.

I did ask and was told it takes 180NM foot pressure on the pedal to lock the fronts up, thats just over 18 Kg so it does not take a lot to stop the car.

Thanks, I've had a quick look on fleabay. There are a few "escort rear slaves" (try searching for that on google ) on there. They look different to the sierra ones in that they only have a rubber boot on one side. I assume that is just their design rather than them only pushing on one shoe ?

On a bit of further investigation (on the other popular forum) the part number seems to be Brake Engineering WC4918/Motaquip VWC345 which
Ford Granada 2 75->77 & ESCORT 1.3 & 1.4 ESTATE, 1.6, 1.8, 1.8D 90-ON, ORION 1.8D, GLX, GHIA, S, EXC ABS 90-ON.

Industry standard correct term is Wheel cylinders

I managed to get some 19mm wheel cylinders in the end from the local Parkers. Not as cheap as fleabay but only a couple of quid difference and much more convenient.
