Info Needed to Swap to Surge Disc Brakes on Trailer

Updated 05/22/2025 | Published 05/14/2025

Question:

I have a 2006 Ez loader boat trailer and I am looking to upgrade or re do the brakes! It has a Titan Model 6 Surg o matic Part 3241639 I am not positive if it’s rated to do disc brakes, hence why I am asking the pro! The trailer model 6-TEZB 19-22/24 5200 vin 1ZEAAMSH96A029167 if you could let me know what you have for disc brakes for it or drum replacements! Thank you in advance Pat

Hey Pat, in order to help you determine what parts you need to convert your EZ Loader boat trailer to disc brakes I would need to know the axle capacity of your trailer as well as the wheel bolt pattern.

In meantime I attached a guide on how to add disc brakes to a trailer as well.

I can tell you that if you have a drum brake actuator right now you would need to swap it to a disc brake one as the two are not interchangeable as they require different PSI ratings.

The axles are #3300 and it has 5 lug pattern and I thought the surge I have was rated with high enough psi to operate disc brakes?

@PatP Thanks for that info! So drum brakes require a lot lower pressure than disc brakes so you would need to at the very least replace the Model 6 actuator's master cylinder with one that was designed for disc brakes. Disc brakes require around 1,600 psi and drum is typically around 1,000 to 1,200 lb. I wish we still carried a disc master cylinder for your actuator as that would have been the easiest solution but we only have drum right now. What we can help with is the disc brake kit that fits your 3,500 lb axle and also has correct wheel bolt pattern like the part # DE66YR.
