255XD Shorelandr trailer advice/questions…

[Howdy Pilgrim]

I’m having issues with my Shorelandr trailer that came new with my 2022 255XD.

I already went through 4 brand new tires after one of them became almost completely bald on the outside tread. I hate to say it but I’ve trailered the boat less than 15 times. Maybe 1k-2k miles total

I called my Yamaha shop I purchased the boat from and went through the process of trying to warranty the tires. Took the trailer to an alignment shop, everything checked out perfect and within spec. They gave me all the measurements and good to go.

Noticed after last time to the lake that the boat just continues to feel like I’m dragging it at times. I have attached photos and it appears that the brakes are engaging and potentially staying engaged on the passenger side of trailer (starboard of boat). You can clearly see the wear between the two sides are not equal at all. Img 6671 is port side img 6672 is starboard side and much much more scored and deeper. This is the side where I had issues with the tire as well

Questions/Advice…
1. What could be causing this to happen
2. What are the replacement parts for rotors and pads? Trailer model YAV51TJXWMS0-16
3. Is it normal for them to brake down this quickly or how often do you change your brakes?

Any help is SUPER appreciated as we have a trip coming up that I have to drive 4 hours each way and just want to try and make it safe

Here’s a thread that I did on the trailer bearings and brake maintenance that may help.

Thread 'Shorelnd’r wheel bearing & disc brake caliper maintenance'

Jan 31, 2025

This one is a long time coming as I had wanted to do a more comprehensive thread after I got home from WI this summer and had to replace a wear sleeve while I was in WI. While the concept of the replaceable wear sleeve is a good one, it sure would be nice if Shorelnd’r would have included bearing maintenance and wear sleeve replacement in the owners manual. As well, the disc brake owners manual leaves a lot to be desired in terms of maintenance as well as parts.

When I was in WI this summer the drivers side front wheel started spitting some grease, I had worked on this wheel a few years...

Have you been checking the hub temperatures when you tow?
Have you jacked the wheels up and checked for excessive drag?

Typically if a caliper hangs up in its travel the results are dramatic.

I have not checked the hub temps. What would those normally be and how are you recording the temps? I guess I would be looking to see a difference between the too and maybe a temp gun?

I have not jacked up the boat and spun the wheels myself. I was told that was done at the alignment facility because the whole boat/trailer has to be lifted but it would be good to double check myself for sure.

Thank you for the link I will dive in and if the parts are in there I will get those coming asap while I continue to diagnose

You should be able to put your hand on the hubs without getting burned… the brake hubs will always be warmer than the non brake hubs.

Good job on getting the alignment checked.

Did a quick glance through your thread and one thing I didn’t catch was the rotors… are those a standard size or something I can measure and go from there? I apologize for my ignorance didn’t think I’d be messing with these this low of miles lol

You don’t need to start throwing parts at this project until you determine what’s wrong. You need to pull the wheels off and go through everything. One tire wearing on the outside edge is weird do you have any pictures?

Here’s a few more threads to look at. In that first one is a couple pictures showing how to push the caliper over with a pry bar, then how to manually pump the surge brake actuator. Do one wheel at a time. Check brake fluid before you begin.

Thread 'Changing out the surge brake actuator.'

Jun 11, 2023

Okay,

A few weeks back I checked the brake fluid in the reservoir of the surge brakes… bone dry. I wonder how long it was like that since I’d never checked it before… boo on me. I’m still baffled at where the brake fluid went to. I know the brakes worked two years ago when the big Mule Deer Doe stepped out in front of me on the way to Lake Powell and I slammed on the brakes, the trailer started hopping and left big darkies on the road, damn that was close, my friend and his wife and their boxer dog were riding with me, he said nothing but his wife made a little squeak noise.

Post in thread 'Trailer Surge Brake Issue'

Mar 30, 2025

There’s a couple of surge brake threads I did, perhaps you will find that information helpful



You will always feel the actuator pull out to its stops when you accelerate after a stop as the surge brake actuator collapsed a bit to apply the trailer brakes. Another thing to do is to have someone help you and thoroughly bleed the system this is time consuming but can make sure the actuator doesn’t have as much...

Are you in salt or fresh water?

Did you check your owners manual for the trailer that came with the boat?

In that first thread I sent you it shows the slider pins, you may need to pull those and make sure they’re lubricated and that the calipers slide freely with the piston collapsed and the tension spring removed.

The pics you included in your first post don’t look that bad, there’s a difference for sure but that could be air in the brake line between the starboard side and the port side.

Thank you so much for this information and the resources! I will definitely go through the list one by one and run this down.

Here’s a pic of the tires. The top is the side I seem to be having problems with while the bottom is the driver side of truck port side of boat. Less than 3k miles easily.

Caliper pistons will also lock up. Mine did and the brakes were always dragging.

I'd compress them and be fine for a day.

They get stuck.
