An increasing number of trailer owners are switching over to disc brakes, and with good reason. Disc brake calipers have only one moving part, as opposed to the many moving parts you find with drum brakes. This means that with disc brakes there are fewer parts to maintain, fewer parts to get damaged and fewer parts to repair or replace, thus reducing the cost of maintenance.
Performance increases as well. Disc brakes deliver consistent braking even at highway speeds, unlike drum brakes, which often show a substantial drop in braking torque at higher speeds. In addition, disc brakes offer a much shorter stopping distance than drum brakes.
Titan's complete disc brake kit makes the conversion easy. Designed for single-axle trailers, this kit includes not only the disc brake assemblies themselves - along with all the necessary lines, fittings and mounting hardware - it also contains the Model 60 Leverlock actuator. This hydraulic brake actuator has a higher psi rating for disc brake applications and includes an electric reverse lockout so that you can back up without activating your trailer's brakes. To use the lockout feature, you must have a 5-pole flat, 6-way round or 7-pole wiring harness.

Is this review helpful?
Installed in Spring 2011. System is bad because:
1) Design of hydraulic tubing kit is very bad. Kit does not allow for the removal of the brake calipers without disconnecting the hydraulic brake line. To repack the wheel bearings the hard tubing brake lines at the caliper must be removed. Frustrating to have to bleed the brakes each time the wheel bearings need to be repacked. A good kit would contain a rubber brake lines for each caliper so the calipers can be removed without needing to bleed the brakes.
2) Outer race of inner hub bearing is a not a common part. OD is 2.328" which is about 0.040" smaller than a standard, common, easy to find, 1-3/8" bearing. To replace the bearing, you must purchase a 1-3/8" bearing, through away the outer race ($$$) and purchase a hard to find outer race (more $$$$). Lost the use of my boat for 2 weekends while waiting to receive this odd size outer race. WHY NOT MAKE THE HUB FOR A VERY COMMON 1-3/8" BEARING THAT CAN BE FOUND AT ANY PARTS STORE??? What if the bearing fails along the road?!? Leave your boat there for a week while trying to find this odd size race? Strongly suggest that you buy and carry extra bearings and the odd-ball 2.328" OD race if you buy this brake kit. Outer bearing is a common 1-1/16". Seal is a common 1-23/32" seal.
3) Hubs are poor quality. One bearing bore on one of the hubs is oversize by 0.0007". Bearing race spins in hub. Thank goodness for Locktite bearing retainer compound! Hubs are pure junk! Check the fit of the bearing races as soon as you get this kit!43485
Service from etrailer was fast and everything I ordered came. The Titan brake kit with actuator works well. The installation instructions for the brakes is completely wrong. Just use it as a parts guide only. You should only be doing this yourself if you have your mechanical act together so the wrong instructions won't be an issue. I would recommend this kit from etrailer to replace your old drum brakes with. 47473
Product shipped super fast. The directions were simple, complete, and easy to follow. Installation was easy and fun, even for a guy with minimal hand tools and NO prior experience working on trailers. They look great, even after a lot of highway driving. Best of all, I am completely blown away at how well these brakes work. They stop my 5000lb boat and trailer very efficiently. I have a lot more confidence towing my boat in heavy traffic now. I would recommend these brakes to ANYONE who tows a heavy trailer. 46734
I have a 1999 Zieman double axle boat trailer. I had issues with the coupler sticking, in turn dragging my trailer brakes. Needless to say, they needed to be replaced.
I found this kit after talking to the extremely knowledgeable customer support folks at etrailer.com. A few measurements and part numbers later, I was in business.
As always, the order process was pleasant and the parts arrived ahead of expectation.
The installation went very smooth. Tandom axle trailer, yet brakes only on the rear. The old drums came off nicely and the new rotors and calipers installed quickly and easily. The instructions show the calipers at the 12:00 o'clock position, so make sure you rotate them to 3:00 and 9:00 respectively.
The new steel brake lines were exactly the right size and installed in the same holes/brackets as the old lines.
I was able to bleed the brakes by myself on an inclined driveway and a clear hose into a clear container. I just used gravity in my favor.
Lastly, I installed a 5-way flat and bought the 7pole to 5pole adapter for my truck.
I was very impressed after the first road test. What a difference! These brakes work great and are a quality product. Wouldn't expect anything else from etrailer.com.
Be sure to add more bearing grease after the first few pulls. I have bearing buddies which make knowing when to add grease very easy.
This is a no-brainer upgrade to older drum based trailers.43877
Instruction were horrid. And wrong. Hoses were for a torsion suspension, not leaf spring type, with three very short hoses. I ended up reusing the old hose, which was twice as long. What was supplied was different than what was listed and shown in the pics.
Having said all that, they work as advertised. Very happy with the performance. 28908
I bought a boat in June. Boat and trailer weigh in at about 2,750lbs. Not enough to legally require brakes in my state but heavy enough that I drove out of my way to avoid a particularly steep hill on the way to the river boat ramp.
I installed the brakes myself; it took the better part of a Saturday afternoon to do it. Admittedly, the second wheel went a lot faster than the first. The hardest part is running the hydraulic lines. Actually it is the planning stage of where to run them. Make sure you buy or borrow a tubing bender for this part. It would be a lot easier if the boat were off the trailer (if you can put in and dock it for the day that would be great).
I've not been running with the brakes for a summer season, on local roads and interstates. Not a problem in the world with them. The stopping power on them is great, almost like the boat is not there. Without them, when you hit the brakes, the trailer would push against the hitch and push the truck forward like a kick in the tail. That goes away with trailer brakes.
This project was definitely well worth the investment.
To determine if the Titan Disc Brake Kit, # T4843100, will work on your trailer you will need to find out the bearing size on the trailer.
The best way to determine bearing size is to disassemble the old hubs and find the bearing number stamped on the old bearings. Remember which was the outer bearing and which was the inner bearing. With the old bearing numbers you can find out hub, spindle, race and seal.

When using the Titan Disc Brake Kit and Leverlock Actuator with Electric Lockout, # T4843100, there is no need for an electric brake controller.
You will need to make sure you have at least a 5-Way wiring harness with a reverse circuit to account for the reverse lockout feature on this type of braking system. The lockout feature will also work with 6-Way round or 7-Way wiring harnesses.

The primary difference between the two disc brake systems is the hydraulic actuator. The actuator on the T4843100 features electric reverse lock-out and is rated at 6000 lbs towing, 600 lbs tongue weight. The coupler is designed for 1-7/8, 2 inch or 50 mm trailer balls.
The T4843500 uses a manual reverse lock-out lever, and is rated at 7500 lbs, 750 lbs tongue weight. The coupler is designed for 2 inch trailer balls only.

The Titan Disc Brake Kit and Leverlock Actuator w/ Electric Lockout, # T4843100, will work with a 6-way square plug if you have a wire that will provide a reverse light function.
You will need to test the wires on the 6-way square plug with a circuit tester like the Quickee Circuit Tester, # 3808, and find which wire is the wire for the reverse lights. Then, you will just wire the reverse light wire from the actuator to that wire on the trailer side 6-way square plug that is the reverse ligh view full answer...
The first thing you will need to check is whether or not your axle has a brake mounting flange welded to the axle. I have included a video below. At the 1 minute and 5 second mark, there is a good shot of what the brake mounting flange will most likely look like if the trailer has one. It will have 4 bolt holes spaced 2-7/8 inches apart on center.
If your trailer does not have a brake mounting flange, you will have to have one welded on by a qualified welder at a shop that does work on traile view full answer...
The best recommendation for a boat trailer is a grease-able hub like the Titan Disc Brake Kit, item # T4843100, that you have selected. At this time we do not carry an oil bath hub disc brake kit.
Oil bath hubs are normally used on heavier duty style trailer axles. They must also be closely watched in situations where the trailer is submerged in water, because the oil will breakdown much faster than grease will when water is introduced. Oil bath hubs can be used on disc brake axles, but stand view full answer...

On the trailer side of your 5-Way flat plug, you should wire the red wire you mention to the electric reverse lockout function of the actuator on the Titan Trailer Brakes, part # T4843100, that you just installed.
You will basically run the red wire from the connector to either of the yellow wires that are coming out of the back of the # T4843100, and then ground the other wire anywhere on the frame of your trailer.

I spoke with my contact at Titan and he stated that the bearing protectors that come with the Titan Disc Brake Kit, # T4843100, are Kodiak Red Eye protectors. He stated that they function much like the Bearing Buddy protectors in that they will relieve pressure if it gets too high. view full answer...
I do have a way you can adapt the vehicle side 7-Way to the trailer so you can use the electric reverse lockout on the coupler. First, you will need an adapter that goes from a 7-Way to a 5-Way flat like # 37385. You will also need to make sure that the center pin on your 7-Way is wired to the reverse light circuit.
On the trailer side, clip off the old 4-Way and wire in the Hopkins Endurance 5-Way Flat Trailer Connector, # HM47910. White is ground, green is right turn and brake, yellow is le view full answer...
The Titan Disc Brake Kit, # T4843100, is compatible with a # 84 spindle for a 3,500 lb axle. We carry different # 84 spindles for the different style axle tubes. If you can tell me the inner diameter of your axle tube and whether it is a round or square tube axle, then I can make a more specific recommendation on the spindle that will work for you. I have also attached a link to all of the # 84 spindles that are compatible with this Titan Brake Kit for you to check out.

The most common type of brakes found on tow dollys are electric drum brakes. This is because electric brakes are typically the more cost effective option over hydraulic brakes and electric brake systems typically require less maintenance than hydraulic braking systems.
There are advantages and disadvantages to both. Electric brakes are usually cheaper to install than hydraulic brakes, but you must have an electronic brake controller, like the Prodigy P2 Brake Controller # 90885, installed in view full answer...
The Titan Disc Brake Kit and Leverlock Actuator w/ Electric Lockout # T4843100 that you referenced would well for you as long as the spindles on your trailer are compatible with the included hubs and the wheels on your trailer have a 5 on 4-1/2 inch bolt pattern.
You will need to remove your current hubs and check the bearing numbers that are stamped on the bearings. This kit comes with L68149 inner bearings and an L44649 outer bearing.
