Hey Todd, welcome back! The most affordable set of self-adjusting brake assemblies I have for a 5,200 lbs Lippert Axle are the etrailer Electric Trailer Brakes item # AKEBRK-7-SA. This is a set of left and right brake assemblies that fit a 5-bolt brake mounting flange. These will save you quite a bit of money over going with the comparable Dexter item # 23-458-459.

Most brake assemblies for 5,200 lbs to 7,000 lbs axles are the same size and have the same 5-bolt brake flange pattern. You do run into some that are specifically designed for certain types of braking systems like ABS but on a 2014 trailer you won't have to worry about that.

If you need new installation hardware, we have the Mounting Bolts and Hardware for 12" Brake Assemblies item # BRKH12. This will replace one axle's worth of hardware.

Are you replacing the stock brakes on your 2014 Keystone Cougar?

Thank you for the reply. My mechanic is going to tear into them in couple weeks and we will know more. He is thinking magnets are weak and seems like it be about as simple buy the whole thing

@ToddT. Buy the whole setup with backing plate, brake shoes, magnets, etc. So easy and everything works!

@ToddT You're welcome! In these situation's it's typically less expensive and easier to swap out the entire brake assembly rather than replacing individual parts.

Todd, Yes, buy the entire package. It is a simple installation and so worth it with the self adjusting setup. The 5200 to 7k axles are all 3” diameter and backing plate hole spacing is the same. Scott
