Stranger,
Thanks for the reply and the suggestions.

1. I bench bled the master. I worked at it until the bubbles stopped, then two more pumps. I'm reasonably confident I got all the air out. Of course, there's always a chance three are bubbles hiding somewhere.

2. The proportioning valve came with the Speedway Motors kit. It's actually a combination valve. It's a PV2 valve, for front disc/rear drum. It happens to be the same valve as my son's square body with the same disc/drum arrangement.

3. My engine is stock. 14+ vacuum. I should be fine with vacuum assist. But, you're absolutely right about hydroboost. If/when I LS swap the truck, I will keep this in mind. Hydroboost would take the braking system to the next level.

4. I've never used a reverse bleeder. I've always bled brakes manually. I'm interested to try a reverse bleeder because I'm having so much trouble pushing the air out the manual way. The one I ordered is the Phoenix v-5 kit. It's been on the market for a few years. I hope the quality level matches the reputation. I like the idea of the kit you use. I'm just not confident in the expense. Which one do you have?

Thanks!
John

1.) Bench bleed the Master Cylinder? Fully... This can be a pain, but very very important.
2.) Check that you have correct Proportioning valve (Combo Valve) Disc / Drum , Disc / Disc and so on, this caused me nothing but headaches for days...
3.) I got so mad, I just converted over to HydroBoost, but really had to. I had maybe 7lbs of vacuum.. .so it was needed. But I will say this, it is really nice system, but not cheap
4.) I bought one of those brake machines. I got the one that puts pressure to the master Cylinder with Air and then I start the process. It works really good, but it takes time to set up. I have tried a reverse system where you vacuum at the bleeder... it was not a good kit that I got, cheap one and it did not work good, but I would not be apposed to trying one the nicer kits for this.

I just hope you have success. I feel for you on this!
