Has anybody here installed one? If so what is your opinion of them?

SWO500030 Land Rover ABS Modulator Shuttle Valve Switch Discovery Series II New | eBay

 

It's cheaper at atlanticbritish. It probably doesn't matter where you get it, it's all the same part from wabco.

 

Thanks jafir. I did not know AB was selling them. I just assumed they were only selling the complete module.

 

You should also consider replacing the o-rings to protect the new valve assembly, Falcon Works, in Tuscon is the only supplier of the 2 o-rings needed and they are not cheep.

 

I can not find the price now, but I remember coming across their website a while back and thinking to myself that the kit was ridiculously over-priced. Does anybody know what size the o-rings are? Wouldn't any o-rings that are resistant to brake fluid work?

 

The o-rings are a special double lip kind. I'm not sure how easy they would be to find in a generic version. When I did it, I ordered JUST the o-rings, and then bought the switch from whoever was cheaper at the time.... AB I think. I think that way it worked out closer to $100.

 

The o rings were a crazy price. I never had bought anything else from Falcon Works due to the the over kill on price. Major rip off.

 

I agree. I just ordered the shuttle valve from AB. I'll just take a chance and not order the over priced o-rings from falcon works. I would rather pay $68 for another shuttle valve and replace it again rather than pay $42 for 2 o-rings.

 

If the switch assembly is dry, then the o-rings are not an absolute requirement. There is no guarantee that it won't start leaking the the future, but the switches do fail by themselves, even if there isn't a brake fluid leak.
