rear brakes dragging

[xplosiveg06]

hey guys, i was wondering if anyone would be able to help me solve my brakes problem. my rears when driving let out a squealing sound from both the left and right drum brakes. the system is bleed correctly and the pedal has a normal solid feel. if i pull the hand brake while driving and hold it on, all the rear dragging sounds go away. the dragging sound i would describe as sounding like a train. i could take pics or a possible video of it making the sounds. thanks

Methinks you need to remove the rear wheels and drums and have good look at the condition of the shoes and drums.

The shoes may be worn out or there may be grit inside the drums.

We won't know unless you give it the eyeball:ermm:

Nissanman is right you have check it out. remeber that the rear brakes adjust themselves when you drive in reverse. Jack it up and turn the wheel see where the sound comes from.

A bad wheel cylinder can cause the brakes to drag, too.

I double on that wheel cylinder. Replaced mine and no problems since.

Did the sound just appear out of nowhere? Or did you just do some work on the brakes? If you pried the drums off you might have bent your backing plate. If so, you'll see a white mark on the plate where the drum is rubbing.

Also, I believe that Z brakes self-adjust when you use the parking brake.

hey guys thanks for the helpful replies i appreciate it. turned out the backing plates were bent on the bottom and hitting the drum.

Thanks

You know, come to think of it, that could be the problem, too.
