99 Jayco 3610 Designer- brakes no longer available??

As long as you have the square, approx. 4" flange attached to the end of the axle tubes, you can replace the whole brake assembly.

Backing plate can be purchased with brakes and magnets installed already. New drums with hub and you can be sitting pretty.

I replace mine last year and upgrade to self adjusting brakes. I wish that I had done that sooner, the self adjusting brakes work so much better.

OR Call Jayco directly.

Try "E-Trailer.com" or "Trailerpartsdepot.com".

I would think the axles/shafts would not need replaced. At most you would need new hubs/drums if pads are no longer available. Hard to believe you can not find pads, magnets or other parts that may be needed on a 99. Are they Dexter axles?
