proportion valve help

Edited: 4/27/2007 11:34:49 AM by sdime2372

Sorry for the childish scribblings on the pic, but this was the best i could do (i don't have photoshop). If you know what the numbers are, please help. Let me know if i've got this right.

1. In from master cylinder
2. Out to front discs
3. Out to rear drums
4. I have no idea what this is.

This pic is just like the prop valve i have, it's the best pic i could find. The one i got did'nt come with any instructions or markings on it, so i'm stuck for right now. Please help.

I know that #4 is the brake switch connector.
Sorry I do not have a car wo ABS so I cannot confirm 100% but I know the master cyl #1 ports are correct as they always go next to the brake safety switch.

So #1 is correct.
As for #3 (rear drum) this fitting would be alone and metered so it provided less pressure than the front disc.

Looks like your estimate is correct to me!

brake switch, what i run the wire from my brake to? thanks for the input, not to diss but does anyone know for sure?

c'mon, nobody knows? i don't want to have to go to auto zone and try to get help without giving them the year, make, model, engine, transmission, serial number, and ac/no ac info.

dont forget to tell them what color your seatbelts are and bring your birth certificate

#4 is for your brake pressure warning light so if you were to run low on fluid it turns the brake light on on your dash there not just for e-brake light

thanks james. Is it necessary to hook that up? What about the other ports, did i get it right on my scribblings?
