Ok the problem i have is I have swaped in a rear disk setup off a 83 fireturd onto my monte, as well as a ford 9" I did a post on how i did that a while back. I still have no rear brakes after redoing the intire brake lines from the master cylinder to the calipers, while excluding the proportioning valve. Seems to me thats what the free mod does that anyway by just remove the proportioning properties of the valve. Just replaced the rear calipers after rebuilding the ones i had didn't work. Still didn't work. Tried new master cyllinder with no luck, it was a stock monte mc but i have heard from multiple sources that it has the volume to operate the rear disk. I have just ordered a disk brake mc but have not installed it yet.

The only other thing i can think of that might cause a problem is that the bleaders are not in the stock location. As you can see in the pic below the caliper is now at the top of the rotor, the only way it will fit on the 9". Sense the bleader is no longer at the highest point on the caliper that it would not bleed right? Sorry this is so long but i wanted to include all the info i have so you guys know exactly what i'm dealin with. Thanks ahead of time.:hail:

 

aww come on guys i'm sure you have some feed back to this. :hail:

 

There's absolutely NO way a caliper mounted like that will EVER bleed properly.

Air rises, so the bleeder screw has to be THE highest point of the "fluid jacket" in the caliper. You may have to bleed those calipers with them "dismounted" from the backing plate. Make certain to put something strong in between the pads or the caliper might "de-piston" itself.

 

Thanks Hawk after thinking about it there is no way it will get the air out. I just needed some one to confirm I'm not crazy. I'm going to try dismounting them and bleeding them and see how that works. Thanks again.

 

Well I tried pulling the caliper off to bleed it and I now own one of the best braking land barges on the planet. Man what a difference. The rear brakes just lock up before the fronts so an adjustable pv valve is in order.

 

You're welcome man. I've been doing brake mods and upgrades and troubleshooting so damn long I'm getting to be halfway decent at it. Glad to hear it fixed your problems.

Just don't forget you'll ALWAYS have to dismount them to bleed 'em.
