Had an issue tonight with my brakes failing and pedal going to the floor.

Car is an 00 RS with full 05 STI swap and Goodrich steel braided lines.

It seems like the RS proportioning valve is leaking when the fluids get hot and then it failed.

They don't make the RS valves anymore according to my dealer, but I could get the 05-06 STI one

Will it fit the RS hard lines?

Any other suggestions?

In Seattle and trying to drive to Colorado next week.

TYIA!

I would get an adjustable one at this point. I would also buy 1/8NPT to -3AN fittings and reflare the tubing to us AN fitting were needed.

I just installed AN fitting from directly flaring the OEM brake pipe on my brothers 96 outback. If you look up the standard subaru uses 3/16 lines but 10mx1.0 inverted flare nuts. An fittings are MUCH nicer to work with plus you dont have to double flare the stupid things.

You can still get an OEM valve from another model that might be close. You will probably still need to replumb but I would bet not by much.

If by full swap you mean front and rear brembos, ABS pump as well, then you should just use the STI "valve" (I recall that it's just a passthrough block to connect the lines).
