ABS sensors?

[dnb]

Does anyone know if the "donor" vehicles for Griff hubs had an ABS option? I think this could be the simplest (and cheapest) way to fit 4 tone wheels and magnetic sensors to the Griff.

The idea is to use my new ECU as a traction control/launch control system so it's a bit more sensible in the winter. (I'll have an off button, so don't worry!!)

Donor is Sierra, ABS was fitted to some models.

Cosworth brakes on a 500, init Peter?

Sierra 4x4 and escort RS Turbo used the same callipers too

The ABS system fitted was a mechanical system which did n't use sensors at all IIRC. BTW use proximity sensors (cost around £50-£75 each for decent ones) not magnetic thingies which are very unreliable.

The Sierra uprights have bosses cast to take the MVR sensors, and the stub axle has the corresponding teeth on it where it passes through the upright. On cars without ABS the bosses are left blank. On cars with ABS they are machined out to take an MVR sensor. If you want to add wheel sensors to a Griffith, the easiest and most reliable way would be to exchange the uprights for ones from a Sierra with ABS.

Just checked my Sierra workshop manuals and it is an electronic system as Pete says. I think I got confused with the Orion/Escort that had a wierd ABS system. Anyway you will need to find a V6 Sierra with rear disc brakes to stand any chance of picking up the parts and even then ABS was still an option.

Why not pick a sensor of your choice and get the upright drilled and tapped to fit? Job done.

Also worth checking the traction control requirements for your ECU. Can you program in different pulse counts and so on. Some even require a input defining which gear you are in.

My neighbour has 4x4 Sierra for sale/spares.....not sure if it has ABS on it.... if your interested let us know and I'll have a chat with him.

Doesnt the ABS sensor detect the steps on the section of the drive shaft?
This is difficult to see in the TVR upright, just remember seeing them when I had it all apart

These are at the diff end.The worst part is therefore sorted for TC

Thanks all. This sounds do-able with standard Ford parts.

TCS software for the ECU isn't actually written yet, so we can design it around the Ford kit. (One of the benefits of an open source ECU )
