Hey Martin,

From what you're describing it sounds like you have 3,500 lb axles so I recommend using the Hydraulic Trailer Brake Kit # AKFBBRK-35 because they have the free-backing feature so your brakes don't lock up when you back up.

If your actuator has the reverse lockout, then you can use the etrailer Hydraulic Trailer Brake Kit # AKUBRK-35 which is the same thing, just without the free-backing feature.

Hey Martin, how did the hydraulic trailer brake kit work out on your aluminum tilt trailer? Your update could make it easier for others with similar dual axle setups.

@Kate. Still looking for parts i believe your comment was 4 lug wheels. In fact they are 5 lugs

@MartinS I am happy to get the right parts for you, can you please respond directly to the email you receive with pictures? Please include a picture of your axle tag. Are you looking for the hub and drums in 5 on 4 1/2", and also needing the hydraulic brake shoes as well? Or is it that the brake shoes are on a 5 bolt instead of a 4 bolt flange? I look forward to getting the pictures so we can get you set-up!

Hey Shaun, thanks for reaching out! The Dico Replacement Master Cylinder for Model 60 Actuator 23361 was replaced by the Replacement Master Cylinder Assembly #T4395100 so you'll want this instead of the Demco #DM24ZR you were looking at.
