Question:
I am looking for replacement brakes and seal for my 2017 Jayco Octane. On breaks it has the following. B12EA-22 Axletek-12-Gg CSA CAN3-D313-M85 Please let me know what you suggest for brakes and seals. Thanks

Expert Reply:
Hey Josh, the replacement for your existing B12EA-22 brake would be # AKEBRK-7R-SA for the right side and # AKEBRK-7L-SA for the left.
There are two sizes of grease seals that fit 7k axles and there isn't a rhyme or reason as to which you may have/need. So if the spindle diameter if 2.2250 inch where the seal rides the correct seal you would need is the part # GS-2250DL or if it's 2.125 inch you'd instead need the part # GS-2125DL.

Hey Josh, did you have a chance to measure the spindle diameter to determine which grease seal you need? I'm asking because knowing your outcome can help others with similar trailer brake and seal replacements.
