Did you replace the calipers?

where did you order a new Master Cylinder from and how hard was that to install?

Could the brakes be sticking, even if I had the brake lock-out in place?

 

Thanks

 

 

I did replace the calipers.  I think I was able to identify them based off the stampings on them and then cross referenced to the UFP catalog (I think I linked it earlier in this thread), and ended up sourcing on Amazon from some trailer store.  They may have come from "Shadow Trailers" as well.  I'm not sure anymore.  https://www.google.com/search?q=ufp+db-35+caliper&rlz=1C1GCEB_enUS966US966&oq=UFP+DB&gs_lcrp=EgZjaHJvbWUqBwgCEAAYgAQyBggAEEUYOTIKCAEQLhiABBjlBDIHCAIQABiABDIHCAMQABiABDIHCAQQABiABDIHCAUQABiABDIHCAYQABiABDIHCAcQABiABDIHCAgQABiABNIBCDc3MThqMGoxqAIAsAIA&sourceid=chrome&ie=UTF-8

The master I got from Boatmate (their parts pricing was better, even shipped). https://www.boatmateparts.com/product_details.php?itmId=1827 

If calipers are hanging up with the master locked out, you either have a caliper sticking like I previously showed in the video link, or you could have a bad hose that is failed internally.  I really truly doubt that's the case for you because it's all wheels at different situations.  I guess it's possible the main feed line is damaged coming off the master cylinder if you have a folding tongue, but I'd seriously doubt it.  

Did you already bleed the brakes?  If so, what did the fluid look like that came out of the bleeder screws on the calipers? 

Also, now I'm just looking for a reason to make a work trip out to the RDU area, if I can/do, I'll make some time to swing by and see what's going on.  Can't guarantee that I'll be out there though.

i'm having issues with aft starboard ballast bag draining (fill up, no issues).  I'm not too familiar with the boat mechanically, usually take it to the shop.  But since they're all booked up I'll try to look at puke, fuse, and clogged pump since i want to use my boat this weekend and every shop is booked.  I'll let you know how it goes! thx

Current system is:

RF head unit (model number?) powering 4 6.5 coax speakers @ 50x4 (I think?)

Punch P400-2 amp running the (two) tower speakers (Alpha II 6x9s - made by wet sounds?)

Punch P600-2 amp running the 12" sub

Sooooo - I took the boat home (new to me) last Friday and the sub worked for about 1/2 of 1 song and quit.  P600-2 amp is flashing orange (circuit protection mode?) at me.  Disconnect sub speaker wires at amp and orange light goes away.  I pulled the sub and it smells like house fire, so that's all done.  But I don't know if the amp could have blown the sub?  Any way to tell before I install another $300 sub (and potentially blow it up as well)?

Overall the stereo seems about 60-70% as loud as I'd like it.  0-22 is almost inaudible, 24-28 is nice cruising, but maxed out surfing it is not really enough.

Thinking about different tower speakers, or replacing the P400-2 with something bigger with more channels and running the 6x9s and 6.5s with it?  I suppose part of that depends on the health of the P600-2 - maybe it makes more sense to replace both with a good newer 5-channel?

Thoughts, suggestions?

My last trailer had 3 out of 4 calipers seized bad, and one would as it heated up.  To be honest, once I got to that point, I decided to just replace the master cylinder as well because the fluid was nasty and rusty.  I figured for as long as moisture was in it to mess up the calipers, the master cylinder was cheap enough to replace for peace of mind.
