We have a ford Escort rear axle with drum brakes and does anyone know of a disc conversion for this?

Which model escort? Rear wheel drive or fwd?….
I did a Google and there are a few options…( most folk say it’s not worth it…)

FWD van it's for our Mobile barrier that is used in side impacts but now due to new protocols with the weight now at 1400 kilo's the drums do struggle.

I'd imagine you're going to struggle to find an easy bolt-on upgrade kit (IIRC the Escort vans never came with rear discs) however it may be possible to cobble something together from the parts bin. Out of interest have you tried to service or upgrade the current drums? It may be easier to bolt on larger drums than discs.

We have full machine shop capability so fabrication and design is not an issue but it would be nice just to bolt on and go, I think we may have to purchase a axle and fabricate the parts then upgrade the barrier to the later spec with minimal testing.
Thanks for the input much appreciated

what about the bigger escorts, like the XR3i or even the focus, ( not sure if the xr had drums?)...
As you got full machine capability, it shouldnt be too difficult to cobble summat together...
Will the wheels have sufficient offset to accomodate discs?

I don't want the issue of having to change the dimensions of the barrier (weight/height/CofG/ alignment) as it tracks accurately as it is and building a new barrier is something i don't want to think about.

Front brakes do 80% of the work to reduce speed, that's where most improvements could be made?
Larger disk set up from the sporty models?

A quick google told me that the only FWD escort that came with rear discs was the MK5/6 RS 2000, but that may not be suitable as they were also available with 4WD so I'm guessing the rear hub carriers are going to be massively different to the Van's. |

Yes this is a solid rear axle it's evolved over the last few years and most likely not thought about to deeply in the early design stage. The best thing is with very little effort it is capable of doing three different tests just by removing or adding ballast. but the brakes are now the major issue.

Does it still use the brake-balancer assembly, like the last of the Courier 55's from the turn of the century? The only issues I had with that particular van was the hydraulic pressure just not getting to the rear axle; a new balancer had to be fitted to one van to get it through an MoT, after that it was fine. Another Courier 55 I looked-at, it just needed the bias spring tweaking to give more pressure.

No balancer we use a nitrogen charged cylinder set at minimum 10 bar, activated by electronics connected to an ram that pushes on a lever assembly directly to a Landrover master cylinder then through steel lines to the brakes, it's simple and it works, just not well enough

Can you adjust the cylinder further down the lever to give more fluid pressure for a longer throw of the cylinder (a bit like elongating the brake pedal, more leg movement to give more fluid pressure)? |

Pretty much on the max, that would have been an easier solution but we looked at it but the pressures would be huge and we think the weak point would be the cylinders so we don't want to chance it. we thought about reducing the brake shoe contact area but this is leap of faith with no guarantee |
