actuator rod?
 

Installing a disc brake conversion kit from ECE. I removed the master cylinder and this is what the actuator rod looked like out of the booster. Doesn't seem right? Especially as it is wearing the rubber dust boot with the splines?? First time working on truck parts...so flying blind:)

Re: actuator rod?
 

There are two types of master cylinder/booster combinations. long rod and short. That looks like the long rod version. Marks on the boot don't send up any red flags for me. If you go to the 60 to 66 general discussion section and go to the FAQ's you will find some very good threads on the boosters and master cylinders.

Thanks for the reply...I haven't visited that area, I'll take a gander. The other thing that through me off was the acorn nut on the end?

In between the booster and the master covering the actuator rod was this rubber boot:

I've never seen a boot like this between these two.....is that suppose to be there?

Most of the time that is not on there when running power brakes.

Thanks for the reply Jimmy. I haven't been able to find anywhere that a rubber boot goes in between the master and booster. I see that the rubber boot i posted usually goes between the booster and firewall for a manual set up. The glove box sticker does not show the truck born with power brakes, so it was probably added by who ever installed them?
