Im lookign for a ABS unit/ porportioning assembly for my car. went through inspection, said I had no braking force in the rear, so I need to swap out the unit, or the porportioning assembly so I can get somethign back there. thanks.

i would personally adjust the shoes before switching that out.

I already did, 3 years ago, with the last 2 of the car sitting. As you know shoes don't need as much pressure to push them out compared to the amount of pressure for the caliper to apply a clamping force.

well to be certain the prop valve is bad, try bleeding the brakes and see what kind of pressure you get from them. very rare for it to go bad. most of the time when cars fail for rear brake balance, its either they are low or not adjusted properly. just tryin to save you a couple bucks. 8-)

It's not that it's bad, but Drum props and Disc props displace different amount of preesure to the rear, with the disc set up displacing more. I had a feeling it wasent giving enough, cause after I did the swap, I saw not as big of a gain as I do see with disc/disc setup. I will bleed since it has been siting 3 years, but it's always felt like that, even when I used to autoX and bleed them on a regular basis

didn't realize you switched rears, could very well be the prop valve then.
