rear drums seem hot

[mopar440bbody]

hello everyone, its finally cooler here and getting to be a good time to ride. i just had a complete rear drum brake job on my 67 coronet and i test drove it . i hear both side making noise from shoes to drums in reverse and forward,,,,,,,,,,,,,,, and it heated up wheels and drums, is this normal and do they need to break in , i drove it in town for about 20 miles. i changed wheel cylinders , turned drums and new shoes. they are hot to touch but it did not blister my finger and i didnt touch it to long or firmly. i also changed all the springs and hardware. it does smell a little bit too. thanks and be safe.

Are they adjusted too tight? The drums will be warm after use, that's to be expected. Jack up the rear of the car, place the transmission in neutral and spin the wheels. There should be some drag, but the wheel should spin about a full turn with moderate force. If not, adjust accordingly.

Also check your e brake adjustment...

Is it possible to put self adjusters on wrong?

No, the brakes only go together one way.

E-brakes adjusted too tight OR not releasing all the way like they should.(especially happens where salt is present on the roads)

I agree with both the adjustment could be too tight and the emergency brake could be partially applied, not releasing all the way or adjusted too tight. Along with that, you could possibly have the primary and secondary shoes reversed (Primary is the one with the lesser amount of lining and goes toward the front of the car, secondary has the most lining and goes to the rear). Ironbuilt's picture shows this. BTW Ironbuilt, where did you get USA made wheel cylinders?

Good Luck, hope you figure it out!

Pull the rear drums & work the e-brk cables, see if the shoes return to fully relaxed state.

You can put the adjusters on the wrong side. There is a left and a right. You have to take the adjuster apart and look on the end, there will be a "R" or "L" stamped into it.

Normally if you have them on the wrong side they will loosen the shoes causing a low pedal.

Sounds like yours might be adjusted too tight.

Since you HAD them installed, I'd say take it back and let THEM inspect and correct it.

Heat is the product of the energy absorbed by the friction of the shoes and drums. The kinetic energy of the car is then converted into heat. If you have heat, its from friction.

It's probably just the shoes breaking in, they come with a somewhat rough texture on the surface.
I would suggest try short distances, stop in a good spot get out and check.
Does the car move easily from a level stop?
Do you notice it not coasting as well as usual?
Burnt shoes do have a strong aroma. It will likely clear up.
