I’m at my wit’s end. I’ve already replaced the calipers twice, brake hoses, and rear drum brakes have been adjusted. What could be wrong? The truck sat for awhile, and my mechanic has been “guessing his way” through things. I just want her running properly. Any help is greatly appreciated, thank you so much.

 

Where the exact problem?

 

In the two front wheels. The rear wheels are fine. The problem was first noted when I leaned against my wheel, and burned my hand on the rim. The calipers were so stuck, I had to use a pry bar to remove them. They were changed out today, same problem. I literally have to pull on the pedal to alleviate the problem, but it doesn’t work all the time.

 

Is the pedal binding?

 

I honestly don’t know what that means, could you please explain? My mechanic said the pedal felt fine though.

 

Has anybody tried greasing the slide pins? Sounds to me like they are binding up

 

The pedal has a pivot at the top. If it is binding there, you are gonna have problems. I would check that carefully......

 

The pins were definitely binding on the old one. This new one is brand new with grease, and it’s still tightly binding to the rotor. It takes force to move the rotor by hand.

 

Is this the pivot point?

 

That's where it pushes the rod for the master cylinder. The pivot pin that the pedal hangs from is further up. Unhook the rod in the picture and see if the pedal swings freely. If it does, your master cylinder is probably sticking and needs replacement.
