You will have the same "seals" on a disc brake
setup that are on your current drum brake system. The seals are part of
the hub/bearing portion of the assembly.
</span>Unless your seals are rupturing due to overheating brakes, switching
from drum to disc brakes wouldn’t prevent this from occurring. </span>As previously stated, the most likely cause
is someone “over packing” using a “bearing buddy” or similar zirk fitting with
an overzealous grease gun operator. </span>Unless
you go to an oil bath bearing assembly which have their own risks, most grease
lubricated bearings will employ the same basic architecture as your current
There is a slight chance that the brake drum / hub or axle
is damaged or defective that is allowing the seal to work its way out, but a
good mechanic should have recognized this during a disassembly or inspection.
As for switching to disc brakes, they will be an option we
select when we order a unit. </span>If the
manufacturer or dealer doesn’t work with you, there are a few other options. </span>I installed disc brakes on my boat trailer
and was quite satisfied with the ease of install, quality of product and
greatly improved performance. </span>I used
Kodiak Disc brakes. </span>A slightly different
scenario, I used a mechanical coupling surge actuator, on an RV, an electric
over hydraulic actuator will be required. </span>You will also have to run hydraulic lines.
There are a few other options like disc size, separate hub /
brake disc or integrated hub / brake disc that you will have to research.
I used Shadow Trailers http://www.trailerandtruckparts.com/...akes_c_17.html
and was quite happy with their service and prices.
