older disc brakes, odd leak

hey trying to nail down a cheap fix for my passenger rear caliper.

it's leaking from the ebrake actuator arm! right underneath the big nut on the backside that ataches to the cable and has a weight on it on the opposite side of the brake.

will a rebuild take care of it, or a new caliper? trying to keep this one very cheap, upgrades can come over the winter, planning on droppingthe rear axle for a refresher, and some paint!
my pads are new and so is the caliper, oddly enough, the drivers side has no problem but we've bled the passenger three times in a month and finally found the leak.

all help is appreciated

There's an o-ring on the actuator screw that's leaking. The whole caliper has to come apart to change it. If it's new caliper, take it back and exchange it.

Re: older disc brakes, odd leak

Or you can rebuild them with the recall kits which should take care of the issue. Depending on your time needs, a replacement from an auto parts store may be what you need.
