Are these brake magnets warn?

I read additional information and articles state if exposed winding is visible they would be worn. I did not see any, I guess. Articles also talk about testing the voltage and ohms. I can start there.

How is the surface of the magnet? If you run your finger vertically, can you fell pronounced ridges like a ripple potato chip? Also check the inside surface of the drum that the magnet rides against.

If the drums and magnet faces are fairly smooth then I would leave them alone for now. Depending on how many miles you plan to tow this year, you might get another season or two out of those.

The magnates look good to me. Way better then the ones I replaced when I had the pop up and TT.

Just going from pic, looks good to me. If they are wearing smooth, and evenly, they are okay.

You will find you are better off to replace the whole backing plate brake assembly rather than trying to replace individual components. It is a matter of undoing two wires and 4 or 5 bolts to replace the whole backing plate.

^^ What TXiceman said.... Far better to replace the entire enchilada, then piece mealing it....

They have 2 different for each assembly - a right side and a left side..

disconnect 2 wires, remove 4-5 bolts, remove the entire assembly and install new..
End result is all new everything except the mounts and wires leading to assembly

I agree with complete replacement being easier/cheaper, but the question is, does he need to do it now? I'd not be in a hurry, going by pics. I do know that things in a picture, can appear better than they really are.

Thanks for the replies. The magnets and drum are fairly smooth. I will do some voltage testing to check their functionality. If any are bad, I will replace the whole unit.

No need to replace them if they are not worn. Yea, its easy to replace the whole assembly, but you stuff looks good. My breaks on the TT needed replacement at about 10 years. And that was probably because they were undersized.

If shoes and drums are smooth them I would leave them for now. Bear in mind that you will need to order new drums when you do brakes...very few shops even turn brake drums anymore, and I was not able to find ANY that would do a trailer drum because the inside face where the magnet rides needs to be turned too.

Last time I did brakes on the TT I got the 4 brake assemblies, new bearings, new seals, and new drums from etrailer for about $500 delivered.

ALSO: be sure you get self-adjusting assemblies, upgrade from that post-WWII technology where you have to adjust the brakes manually with a brake tool.
