If your disc brakes like the Kodiak Disc Brake Kit # K2R35S are not releasing it is likely an issue with the hydraulic actuator. Oftentimes this is the shock of the actuator having gone bad so it won't release all the way, so that would be the first thing to check; you could possibly replace it if that is the case. For example, if you had a Titan Model 60 Actuator you could use the Replacement Shock Absorber for Titan Model 60 Brake Actuators # T2336200.

Thanks for the additional info, and the Kodiak brakes were just an example, the brand doesn't matter although the fact you have electric over hydraulic certainly does. Due to this, if your brakes are not releasing there are a myriad of potential issues you'll need to troubleshoot. It could be the brake controller, so I recommend checking the the wiring, specifically the stop light switch wire to ensure it is not contacting another circuit that carries 12 volt power, which would cause the brakes to constantly be on. This could be the wire being loose or somehow damaged or frayed causing a short. You want to use a circuit tester to ensure this wire only carries voltage when the brake pedal is applied. Also, check your brake lines, and you should probably bleed them to ensure there is nothing that is causing any type of issue.

Hey Larry, Good question but the Kodiak Disc Brake Caliper Rebuild Kit for 3,500 lb to 6,000 lb Trailer Brakes #KDBC225KIT is not limited to just the stainless steel calipers. So if you have a 225 caliper like the dacromet, for example, this kit will…

It is certainly possible for any axle to wear out enough over time to need replacing. Since the suspension is built into a torsion axle if the suspension part was to wear out pretty much the only solution would be to replace the axle. If the…

The side of the Silicone Dust Boot #K225BSSI, that comes with the Rebuild Kit #KDBC225KIT, with the design on the outside ring needs to face in towards the piston while the other side should face the brake pad. I have attached a photo to demonstrate…

You shouldn't be experiencing issues with bleeding the brakes with a Vacuum Brake Bleeder, like part #PTW87030, after installing the Brake Actuator with Electric Lockout #099-175-20. It sounds like you might have a clog somewhere in your brake…

You should not have any problem fitting the Kodiak Disc Brake Caliper, #KDBC250S, in place of the #KDBC225S. The major difference is the piston size (1/4 larger on the 250). The 225 is designed for 3,500 to 6,000 pound axles whereas the 250 is…

Yes, the temperatures you mentioned are normal. If you were getting over 200 degrees that would be a bad sign. But typically if all of the hubs are the same temperature you're good and it's only really an issue if one of the hubs is hotter…

Answer 10

You will want to check your calipers for the number stamped on the outside between the two bleeder valves. (See image) If the number is 225 (calipers rated for 3,500 lbs - 6,000 lbs), then the correct brake pads are part #K225CP that you referenced.…

Answer 11

The "KTC 7600" stamped on the brake pad doesn't look to be a part number, so I can't cross reference it, but we do know you have Kodiak ceramic brake pads. So to determine the correct brake pads, all you need to do is match up…

An aluminum wheel like the #AM25DR is actually the best option for boat trailers. Aluminum is rustproof which makes it ideal for salt water applications. As long as you're looking for a 14" wheel with a 5 on 4-1/2 bolt pattern this is a…
