replacing brakes on 5th wheel

[mazboy123]

when brakes are replaced do you usually get just the pads or the whole brake assembly? and if the whole assembly do you get the bearings/seals replaced at the same time????? what about the drums?

I have a 16K 5th wheel. just wondering.

I prefer to get a "loaded" backing plate. They will have new springs, shoes and magnet. Unless the drum or bearings show unusual wear or damage I would re use them. Don't reuse the grease seal and make sure you order the right size and they are right and left handed. Measure the diameter of the drum and the width of the shoe.

Replacing the entire backing plate insures new components, takes less time than rebuilding. When you reconnect the wires it doesn't matter which wire to which, just make sure they are connected good.

Most RV's use either 10x2.25" brake shoes (smaller trailers) or 12x2" shoes (most likely what yours uses).

E-trailer sells the parts or the whole assembly. Here's "sort of" the way it breaks down:

Whole assembly ready to bolt onto your axle: $44.95

Brake Pads ($27.95) and magnet ($18.95) TOTAL: $46.90

So, without getting into quality or "one brand is better than" discussions, it's pretty much a wash in price as to whether you buy the individual shoes/magnet (and use your old hardware) or just buy the new assembly ready to install (and omit the "hassle of rebuilding")

As for bearings and races, if it were me, I'd buy new seals, clean, inspect and repack the bearings. If, when you disassemble your hubs and find a damaged bearing or race, NAPA and most auto parts stores have bearing sets available. Usual cost is about $6-7 for a bearing/race set. I wouldn't buy bearings unless you've got better than 50K miles on them or know they are damaged. Usually bearings will go better than 100K if cared for properly.

Good Luck !!!

ADDED: I see chuckster57 was posting the same time as me. It looks like we're pretty much in agreement

I watched a great utube video on changing the complete assembly last night, step by step. Looks simple just takes a few hours doing things 4 times.... ( 4 wheels)
