1990 Pirata Trailer Brake System Overhaul

[rludtke]

Does anyone know who manufactured the trailers back in the late 80's and early 90's? Or what size drums and bolt pattern came equipped on a 1990 Pirata trailer?

I want to overhaul the brake system, but I don't know what parts to get. The trailer has 4 hydraulic drum brakes with hydraulic hitch actuator. Currently nothing works. I want to replace the actuator, hubs, and brake assemblies. I was looking at all the options available on E-trailer and realized that I don't know what I have.

My trailer was overhauled last year. It is the original trailer sold with my 1990 SunSport. Yours may be similar. The attached photos have all the info I have on it. (Note the invoice excerpt has part numbers for the replacement actuator they used.)

Also, Mischief IV, what program do you use to attach your large, beautiful photos?

Thanks,
MySupra

Original Supra trailers were made by a company called SMP (Sweetwater Metal Products) There really is no information on them.
What you have on your trailer is pretty standard still today but yes, you will have to figure out what size you have. Most of my SMP trailers have 14 inch rims from factory with 5 lug, 4.5 bolt circle diameter. Tires are ST205/75R-14

Your bearings and races should have numbers on them once you take them out and clean. Just replace with identical.
Here is information off my '83 SMP trailer.
Inner Bearing number - L68149 $9.99 @ Northern

Inner Race number - 68111 $7.69 Napa Auto Parts

Outer Bearing number - L44649 $12.99 O’Reilly Auto Parts

Outer Race number - L44610 $5.99 @ O’Reilly Auto Parts

Grease seal - National #473317 $14.99 O’Reilly Auto Parts
Inner Diameter, 1.687”
Outer Diameter, 2.325”

As far as brakes, measure to find the match on eTrailer. If it were me and I were redoing it all, I'd get rid of the hydraulic and go with electric brakes. If you're just replacing a few parts, then stick with it.

Yup, so much better isn't it? Shame the forum can't load pics like this. I guess nowadays there is no reason to update old tech being only 3 of us post here. What a shame everyone had to jump ship to Facebook.

Boat looks awesome, gonna have to make the trailer match now.
