gentleman,

I have a leaky proportioning valve, and I may need a replacement. it seems to be seaping out of the front of it some.... regardless, previous owner did a 5 lug swap, and I'm not sure if the proportioning valve is from sn95 or a factory fox or what. any input would help. thanks...

Hard to tell. It has the line on the rear like an SN95, but that could be swapped to the fox combo valve. How I did my 5-lug swap.

However, looks like the stock plug is in the front. Tells me the valve never got gutted. There's an oring under that cap that can be replaced.

What's your brake setup again? You might just want to gut the PV and install the ford Racing prob valve plug, and an adjustable PV.


Or you can do the max motorsports PV delete kit

Or it DID get gutted and he didn't use the FRPP plug. It needs that plug or it's likely to leak fluid out and air in.

That is true, without the guts, the rubber nipple on front tends to leak

That rubber O Ring has a tendency to leak under that front nut.

It does get rid of all that rusty junk.

The MC can compensate if a line loses fluid. The stock valve does also have a shuttle valve, but to be honest, all of the valves I've disassembled have had the shuttle valve frozen up anyway.

I'll prob do the Max motorsports delete my next time I mess with those lines

I'll look into the kit. as far as setup goes, to my knowledge, everything was parted out from a 99-04 GT.... but I'm not 100% on that
