Hey Mike!

Once you install new electric brakes on your trailer, you'll need to follow the bed-in process so the new shoes and magnets can properly seat against the drums. You'll need to find an open stretch of road to begin and then accelerate to about 40 miles per hour. From there, you'll use the manual override on your electric brake controller to slow the tow vehicle down to about 20 miles per hour. You will need to repeat this about 20-30 times with time for the brakes to cool between each stop. Once they're bedded in, you should notice the braking performance improve and you'll be good to go. Without the bedding process, your brakes will feel very weak. I've linked the full process below for your reference.

What kind of trailer are you installing the brakes on? Is this a new install or a replacement job?

I am / have replaced all of the brake assemblies on a dual axle 7k toy hauler. The pad had lost adhesion on one and I expected they were original equipment on a 2001 trailer. Ive read that heat stress cracks are common. New dexter self adjusting and considering replacing drums with bearings. Suspension will be another issue for another day.

@Mike Got it. Yeah, I'd say definitely due for a replacement. Sometimes it's hard to tell how worn the brakes were until you get the new ones installed, so I'm glad you got them taken care of. I'd definitely replace those drums and bearings as well and then you can keep track of the maintenance from there and maintain them all together. If you know what size you have, I can get you a recommended replacement.
