Where to put proportioning valve?

[ITLBTU]

Do I put it in front of the factory metering block or after? My '69 Camaro was drum/drum, now it is disc/disc? I'm thinking that it should be after, but if you know for sure please chime in.

Thanks

If you put it before the factory block, it will set off the brake imbalance switch on the block.

I wouldn't even use an in-line type anyway. I like to install 3rd gen. Camaro combo/prop valves for 2 or 4 wheel disc brake conversions. I use them for all of our Camaro and any A-body disc brake conversions. The weight bias is a good match for them. I bend all my own lines for them and this way I can route them however I want.

Gmachinz,
So you say instead of getting an adjustable inline prop valve, to use the factory 3rd gen camaro part? Got a part number?
thanks

...last time i checked they are no longer available over the counter.

i haven't had luck with the disc/drum unit.

Does the 3rd gen use a bubble or inverted flare?

[k9ulan]

combination valve?

[MrQuick]

combo valve uses the standard flare, same as your older car but the fittings are odd ball. If you go to the wreckers to get it make sure you cut the lines after the fittings a take with it.
