He also charged me $111.00 ($6.00 parts & $105.00 labor) for checking and adjusting the brakes.
I like the dealer but would like to know if his charges are in line with what other Airstream owners are paying for similar service.
Normal time for a normal major brake is as follows. Rusted or damaged parts changes the picture.
1 axle 1.5 hours
2 axles 2.5 hours
3 axles 3.5 hours
A major brake is defined as follows.
Jack up the trailer.
Remove the hub and drums along with the tires and wheel.
Look for any damage or excess wear to those parts.
Inspect the magnets for wear.
Inspect the brake shoes for wear.
Remove the grease seals.
Clean the bearings with a solvent.
Pressure pack the bearings.
Clean all the dirt and grease off the the complete backing plate and hub and drum.
Deglaze the brake shoes.
Scuff the drum armature plate and shoe surface.
Clean the dirt and scuffings from the shoes and hub and drum and spindle.
Inspect the adjuster springs.
Install the inner bearings.
Install new grease seals.
Install the hub and drum back on to the axle.
Install the outer bearings.
Tighten the bearing retainer nut to specs.
Install new bearing retainer nut cotter pins.
Install the grease caps.
Adjust the brakes to specs.
Remove the jacks.
Replacing any parts is extra, such as the magnets, shoes, adjuster springs, shocks.
Of course, balancing the running gear at the time of the 10,000 mile major brake, is also essential.
It's Sunday and fathers day. I probably forgot something.
A major brake should be done every 10,000 miles or once a year, which ever is first.
Using the trailer infrequently, is not a justification to not do the once a year thing.
All kinds of things can happen to the brake/bearing system, even if the trailer made one trip. Rusted parts is another reason.
Tread separation can happen, even if the trailer did not move.
Ball park, every notch out of adjustment electric brakes become, represent about 1000 miles of wear.
Electric brakes, are not self adjusting.
