Just curious if anyone has any ideas on something...The last two mornings when I leave for work, I get to the first stop sign, my brake pedal is real soft. This morning, I didn't think it was going to stop. After the first stop, the brakes feel normal. Except for one thing. While driving it feels like the brakes are being applied slightly. Not constant but noticeable.
Brake fluid is fine. Emergency brake is not stuck. Thought about bleeding brakes, but weather not cooperating. Any ideas

 

Just as a precaution, any signs of leaking fluid anywhere? Specifically from the union bolts, or brake pistons?

Sounds like air in the system. Service manual says the same thing - bleed the brakes first, and go from there. After that, I'd go after the vacuum booster and master cylinder.

 

How many miles on the truck and when did you last flush the brake fluid? Is the level in the master cylinder reservoir at the right level? It sounds like your master cylinder may be failing, but make sure there isn't a leak first.

 

Could be the rears are way out of adjustment as well.

 

Good weather on Sunday. I will let you know what I find.

 

After jacking and pulling all the wheels off I'd have an assistant pump up and hold the brake pedal while you go around and look for fluid leaks.The rear adjuster mechanisms love to seize up on these.This causes the rear brakes to go way out of adjustment and overwork the front brakes.
I lube the pivot contact surfaces with anti seize.

 

Found the brake issue, but found new problem. Drivers rear wheel cylinder was leaking. Replaced cylinder, drum and shoes. While bleeding I found the passenger side stabilizer bar link is broken. Might be the reason it doesn't feel right in turns. Do you have to change both sides? How tight should the should the nuts on the new one be?

 

Usually about 20 lb-ft.

 

While you CAN replace one end, it's generally MUCH easier to drop both ends. Undo both and the bar will swing down. Swap the hardware and swing it back up. I've replaced one end while doing field servicing but you're trying to twist something that is designed to be difficult to twist. That's how it reduces sway. Plus, I'm old now and don't do more than I have too. Plus, the second one is probably the same age as the one that broke.

 

Replaced both stabilizer links today. Feels much better. Thanks to everyone for the help
