    Spawn Owners - Brood Fork Service Manual/Instructions?

    Any Brood fork owners out there who have done a basic seal service? Spawn sent me a seal kit, but didn't include service details such as a recommended procedure for removing the lowers, oil weight and oil volumes for the lowers, etc. I've emailed them a couple times asking for this info but they have not responded (I know they've been really busy opening up a storefront in Squamish so that isn't too surprising). I'd really like to know some of these details before I pull the thing apart.

    How To Service Brood and Lil Shredder 20" Forks

    Hi guys, demo (aka Brian at Lil Shredder) did me a huge favor and walked me through servicing these forks. I quickly found out (after seeing a bunch of other iterations of this) that he was the designer of the fork and is a pro and servicing it. He happened to be super cool guy and answered all of my questions. Nevertheless, the video isn't perfect as I didn't start videoing early enough in the process. There are pics which fill the gaps and if you watch the whole video before tearing into it, it'll fill the early gaps by seeing it re-assembled at the end. Side note, you can shave down the bottom out bumper and get more travel out of the fork. There is a hard stop in it that you can notice if you remove all the air and cycle it slowly. Shaving that yellow bumper down can give you back closer to a full 80mm of usable.


    You'll need a few items:


    1- 9mm deep socket
    2- 1 1/16th chamferless socket (you can machine down a normal socket)
    3- Two O-ring that Brian has
    4- Slick honey
    5- Some oil, Fox 20wt works...maybe 5wt would be interesting?
    6- Rubber mallet
    7- snap-ring pliers
    8- Some normal, mid-sized pliers
    9- Bike stand clamp or some soft-vise to hold the fork
    10- Shop rags, ideally lint-less
    11- Nitrile gloves are never a bad idea
    12- Small hex, a 2mm I think

    I had no plans to open up the damper, but is there no lube oil in the lowers at all? The oil residue on the dropouts and rebound knob would indicate that there is. Sure would be nice to know how much to put in there.

    Yeah man. Keep pinging them . I'd like to know this as well. How much oil, what weight oil and if there is any oil in the airside etc. FWIW ours is working fine, I'd just like to keep it that way. I also have a sneaking suspicion that there may be a way for me to move from 80mm of travel to 100 and slacken it out a bit more too something closer to 67d. We could really use it. So man, if you do take it apart, please take a bunch of pictures.

    Heard back. No lube oil in the lowers. Recommended applying some teflon-based grease to the seals and bushings.

    Cool, have you taken yours apart yet? I'd love to see the video and tools used.

    teflon-based grease...that is not slick honey is it?

    Clean and lube the lowers with Slick Honey. The cartridge is non serviceable. If it goes back you replace it. I've taken lots of them apart. Let me know if you have any questions.

    Thanks Demo, what tools are needed to do the job. Anything special?

    A little allen key to get the rebound knob off and a deep socket to pull the bolts. Then the lowers slide right off. You could then take a spanner and pull the nut off the end of the stanchion on the air rod side. First let the air out of the air chamber. Then then put the shock pump on and pump till the air rod and piston come out. I then lube the o-ring with Fox fork oil. I then pull the top cap off the air side and lube the o-ring on the top cap with fork oil. Next reinstall the air rod and air rod nut and tighten. Follow up with a table spoon of Fox oil on top of the piston and reinstall the top cap. I find the forks to start loosing air over time and this seems to remedy the problem. I do have O-ring for the forks if needed.

    Hey demo, quick question...is there any sort of spacer or something that would allow someone to bump up the stock travel from 80mm to 100mm? They make a 100mm fork and I'm hoping its actually the same fork but with a reducer in there or something.

    If their is a spacer on the fork it would be right under the White ring with the roll pin in it at the upper end of the air rod. Its Black and about 20mm long with a split in it.

    Hi Demo, our fork is feeling a little less plush and dry (hard to explain). I'm guessing I should take it apart and run through the procedure you mentioned.

    Questions:
    -How can you tell if the damper is good or bad? I'm curious as to what to expect.

    -The fork does feel a little linear but I'm not sure if it's possible to increase the ramp up with a volume reducer.

    -Also is there a seals kit or anything like that beyond the o-ring you mentioned... Or is that not needed?

    -What weight of Fox oil do you us? I have 5wt and 20wt, all fox stuff for my 36grip2 as well as slick honey.

    -I don't have a chamferless socket head to remove the top cap... Is there one you recommend? I have a special Fox one for my 36 buts that's it.

    Update: I added a service procedure video from this fork based on watching Brian @ Lil Shredders do it. Its in the second post of this thread. Brian! You the man! Thanks again and for everything you've done for kids bikes. It was cool to hear how you pretty much started the whole "legit kids mtb" industry. Cheers.

    Oh, after a full service, the fork was SUPER buttery smooth again! My kid noticed it immediately as it was feeling dry before and not nearly as smooth after him hitting it hard for a year.
