Okay so heres the situation.

Finishing up the 4 wheel drum to 4 wheel power disc conversion on my 71.

The master cylinder is bled without a hitch, installed and lines connected. As I begin bleeding the rear passenger side, its obvious where certain lines need tightened...

I tightened all leaking connections as well as bleed the rear calipers. Both have a steady stream of fluid with no signs of air.

When I move to the front I begin to have problems... after a good 20-30 pumps there is not much progress being made on the passenger side. I switch to the drivers side and check the situation. Both sides are dribbling with fluid but mainly air is coming out. Regardless of continuing to pump, the fluid flow does not improve.

After getting furious as well as frustrated, the only thing I can think of is that when CPP sent me the assembled front spindles the calipers were ON THE WRONG SIDES. As it sits now, how they gave it to me.... the rear calipers have bleeder screws on the "top" of the caliper. The front ones have the bleeder on the bottom side of the calipers... I could hear air and fluild mixing somewhere in my front system as a fellow gearhead was pumping the brakes. I had no idea where this swishing gurgling sound was coming from. Could it be that this noise is from the calipers? The fluid is going into the caliper's small reserviour, and since the bleeder is on bottom.... its just going past all the air trapped above the bleeder.


Can anyone throw me a piece of advise? Or do you think my suspicions are correct and I should switch sides with the calipers?

I've always heard, "Make sure the bleeders are on top". I would suspect this is your problem...

bleeders always go up.not knowing which calipers you have i wonder if you can switch sides maybe the right is on the left because bleeders always go up.any way if you cant flip them pull them off and put something between the pads (to hold them apart)and bleed them with the bleeder at the calipers highest point you'll be done before you know it.GL!

The calipers are the C.P.P disc brake kit, as far as I can tell they are some chevy oem style calipers.

Thanks for all the help, I guess the problem is just that calipers need to be switched. The bleeders should definatly be on top. The caliper bolt patterns are the exact same on both sides and the calipers themselves are pretty symmetrical in shape. They should be easily switched.
