The Stovebolt Site Forums The Shop Area General Truck Talk 55 2nd 3/4 dual master upgrade

I finished installing all new brake system, dual master, new slaves, pads, pipe, and hardware. I used the dot3 as you guy's advised. I bench bleed the master installed and bleed the brakes starting with left wear [longest line] then right rear, then front right [longest line in front]and then left front. the master came with a 4 inch plunger treaded into a clevis pin that bolts to the lower end of the brake pedal. I could not adjust this out anough to remove 3 inches of play in pedal prior to engaging the piston or to bleed the brakes and had to make a 5 inch plunger out of a number 8 3/8" bolt. the pedal still seems to feel soft for the first 1 1/2 of travel, then it is hard and braking is felt at the wheels. I have adjusted the pads untill they grab and then backed them off just a little. Any ideas on this? or do I need to make a 6 inch plunger. Has any one install this dual master kit from CCP in a 55 2nd 3/4 ton and if so how did it go?

any help appriciated.

Sorry about the confusion, I meant to say CPP, Classic Performance Parts. Also I solved the problem and now have perfect brakes. I still needed the longer 5 inch pin from the brake pedal to the piston of the master cylinder, however the real problem was that I had not completed the pad adjustment as called for in the shop manual. you first adjust the lower star adjuster until you feel drag, then the top adjuster to eliminate the drag, hit the back of wheel with a rubber hammer to make sure the brake pads fall into place and then repeat the process untill adjusting the top adjusting nut will no longer remove the drag. once I had done this to all the drums the brake pedal was nice and stiff at the top. hope this helps someone else because I was scratching my head for several day's

Good info. I hope to do the same upgrade in the future. Thanks.
