There's no sensors like that on the Sierra ABS system except for fluid pressure (and level). The fluid sensors are all up front with the hydraulic unit.
The only thing I can think of is a one-way (non-return) valve, but if I remember right, it's a simple pipe from front to back, as all the fluid pressure regulation is taken care of up front by the hydraulic unit and valve block. |

It is indeed a pressure reducing valve, it needs to be there in case the abs goes out due to a fault, otherwise looking at the brake pedal would have the car locking it's back wheels.

I'm pretty sure it's on mine, but don't take much notice unless I need to, will try to find out tomorrow.

The valve is V86BB-2M058-AA, part number 1637851, and it was £140.76p.
It is NLA unfortunately, I would look for a pattern part, failing that another rear disc sierra should do. It may be possible to repair yours though, if it comes to it. tabetha |
