Brakes. What In The World Happened?
I noticed the brakes on my 2011 Jayco 32BHDS seemed to be lacking on our second to last trip. Then, on our last run, they seemed really light regardless how hard I braked, and even with the brake controller at 10, fully engaged.
Today, I pulled one rear hub to find the seal must have failed, and there was grease on everything... drum, magnet, shoes.etc. Figured while I was at it, it was time to repack the bearings, and replace the seals. Took me two hours on one hub. Mostly because it was a bear to clean all of the grease, and also because the last repack I did was over 30 years ago.
Wrapped up the one rear hub,and moved to the one ahead of it. No grease, but tons of black brake dust, and the armature surface and magnet are scoured. Repacked that hub assembly, put the tires on, and tried the brakes. Squat. Readjusted them manually to tight, backed the adjutment off, and no better. If I squeeze the controller all the way, they lock up, but spinning the wheel by hand and applying the truck brakes to the floor and I can still spin the wheels by hand.
After getting frustrated, I went to the otger side. Found both were not full of grease inside the drums, but the same scoured condition with the armature faces and magnets existed. Also, the springs on the tab that hold the manual adjuster wheel from turning were broken and the cables were flopping around.
Now, I can only assume that the hubs were overgreased by the previous owner, and maybe the longer trips this year heated the hubs up and the grease expanded and blew the seal(s). I expect that the overload on the other brakes caused the scouring of the armature surfaces and magnets.
I am in a tizzy about what to do. Shoes and magnets cost as much as the complete brake assembly, and i cant find the replacement springs for the adjuster wheel tab. Two sets of shoes have grease on them, and the other are glazed. No brainer. New shoes all the way around. I guess I can see if the local NAPA can turn the drums, or if the scours are too deep.
Wow! What happened? This simple deal has turned into a $400 project in minutes. I assume the wheels that I repacked are not braking with the vehicle brakes due to the scoured armature and magnet surfaces and the grease on the shoues (although I cleaned them with brake cleaner), but wouldnt they be hard to turn by hand with someone standing on the truck brakes? The full brake controller applied locks them solid.
Replies are appreciated.
