    They don't make them for our stock 9" brakes. Where can the lining material be purchased for DIY relining?

    You might try Walcks, but the relined shoes are available at just about any jeep parts place or your FLAPS.

    BTW ceramic linings would be way overkill for a vintage Jeep IMHO, and might actually make stopping more difficult because they may require more pedal pressure.

    The only time ceramic or semi-metallic linings should be used is with a brake power booster. That is what they were designed for. They also wear out drums and ritors much faster than organic linings. If you do not have power assisted brakes DO NOT use these linings. They are far too hard for manual brakes and you will not be able to adequately stop the vehicle. Especially with 9" drum brakes which are barely adequate to begin with.
    Why would you want them I have to ask?

    What Nick said!!!! I tried semi-metalic on 10" drums about 3 decades back and to put it short: they suck

    I think you will get best results with a soft organic. May have to replace them more often, but you can actually stop.

    I want the Jeep to be able to stop reasonably well without changing the brakes out to 10s or 11s.

    No such thing IMO. If you are going to travel over 30, they are not adequte in my experience.
    Even just 11inch drums front is almost enough.

    My understanding is metallic primarily help dissipate heat build up, and thus reduce fade, under extreme conditions such as in racing or heavy commercial vehicles. Doesn't sound like the average jeep.

    Thought about adding a remote power (vacuum) booster to your jeep, like they did back 'in the day?'

    Using semi metallic linings will make a bad situation worse.
    The only way to improve braking will be to upgrade to power assist or upgrade the wheel brakes, either to larger drum brakes or discs. It's a simple matter of friction surface area.
    If you upgrade the 9" brakes to power assist you chance overheating them very easily because of poor heat dissipation. Remember, these vehicles were originally intended for slow speed use and were built with that purpose in mind.

    Sometimes they were fitted with a Hydrovac, which is a remotely mounted vacuum booster that operates a hydraulic slave cylinder to activate the brakes. With the pedals in the floor, your options for boosting are limited. There is also an electric power brake booster that can be mounted remotely - sometimes used in hot rods.
