Bleeding CB Wide Five Brakes

[Bryan67]

I can`t seem to get any pedal out of brakes. I`m runnung the usual T III rear drums and CB wide five discs in the front with a 67 MC and a residual valve for the back. I seem to remember something about having to remove the calipers and hang them upside down to bleed. Something about the line inlet being above the the bleeder screw? Anyone?

The Bleeder Screw has to be above the inlet on the Caliper if they are below try swaping the calipers from side to side most calipers are right or left the bleed always goes to the top most replacement calipers come with two bleed screws so they can be used on either side

Unbolt them and put them on top of the disc so the bleeder points up. Took about 10 minutes with my mityvac.

Thats what I thought. Thanks NoBars.

Well, I pulled the caipers off and moved them to the top of the rotor. Things are better but I`m not rally happy yet. I only have about half pedal and the pedal is still real soft. It feels like I can force it into the floor. Hopefully it will get firmer in time. I`ve had some of this when i`ve done 4 lug disc before but not this bad. Feels kinda like power brakes. I haven`t driven it yet though so we`ll see.

Could be the residual valves causing the problem.  Try taking them out if you can do it without having to re-do your brake lines.  I've never had much luck with those, personally.

The residual pressure valve should be in the front brake lines (to the calipers) not the back. The idea is to hold the pads slightly in contact with the discs at all times, rather than the pedal movement being taken up with pushing the pistons/pads all the way out each time you use the brakes.

i have mine installed (residual pressure valves) on the front with the bigger talbot brakes and indeed it works really well. firm brake and it never fades. i did however have some work to set the drums at the back. and it was the drums that needed machining to make them round again and not eggshaped to fully cure all pedal problems.
