Question 1

Will this replace part # 52860? 8lug 3inch tube

Accepted Answer

My axle was a 12” hub by 2” wide brake pads. The brake housing has a center hole that you need to measure along with how many nuts that it takes to mount. Mine took 5 some take 4. As you look for the new brake assembly you will need to know the details to make sure you get the correct brake assembly. Hope that helps you.

Question 2

will these work for a PJ dump trailer? it has 2 7k axles and 8 lugs

Accepted Answer

It should. Mine are the same 7k axles, 8 lugs and they work great.

Question 3

Self adjusting? Saw two different answers.

Accepted Answer

The trailer brakes are NOT self adjusting, unlike most drum brakes on cars and trucks.  There is however some "give" with an electric braking system on trailers. The adjustment is pretty simple and need to be done when installed and periodically thereafter. 
To Adjust: the bottom side of the drum brakes between the brake shoes you should see the "Adjuster" with a spring between the two shoes- This screwed wheel is your adjuster.  It will need to be manually adjusted on install- to do that remove the rubber plug on the back side of the Backing plate and using a large flat tip screw driver or  brake show adjuster tool and rotate while spinning the Drum until it stops the drum. Then Back the adjuster off just a little until the drum spins easily again. Replace the rubber plug. Do this for all Electric Brake units.
