Video Transcript for Redline Trailer Brakes 7-5 Review

Today we're going to review part number 7-5. This is the 3/8ths inch size brake mounting bolt for 12 inch brake assemblies. Now this brake mounting bolt is used to attach a brake assembly to your trailer. The size on this is a 3/8ths inch by 24. 3/8ths inch meaning the diameter of the bolt size right here. 24 means 24 threads per inch. Now this is a grade 5.

If you see the markings on it, there's 3 marks. That means it's a grade 5 bolt. A few measurements on this. If we do the overall length from the very top to the end, it'll be right at 1 and a quarter inches. The threaded portion is right at 1 inch. Now the head size on this, I pulled the socket that it's made to fit.

It's using a 9/16ths size socket to fit the head, which you use to tighten it down or take it off. This is also to be used with two separate products that you'll need when you install your brake assembly. One would be the lock washer. We do sell that separately. It's listed on the product page of this bolt as a related product and that's part number 38LW.

The other one would be the nut, which is part number 38N. This is the 3/8ths inch size nut and this will also be listed on the products page as a related product. This would all be used to put your brake assembly onto your trailer and just to give you an idea, the size on the nut would also be the socket size of 9/16ths. That should do it for the review on part number 7-5. This is the 3/8ths inch size brake mounting bolt for the 12 inch brake assemblies.

Replacing the brakes on a 50 year old FAN camper. After being assured that it had 10 inch brakes by another company"s "expert" because it has a 3500# axle, I finally received the correct 12 inch brakes from eTrailer. They arrived very quickly, and packaged well. The installation went almost as easy as the very helpful online video showed. Only difference was I had to slightly tighten the brakes to slide the hub over them, even though they are self-adjusting once in service. I have never owned or worked on a trailer before, and the installation was relatively easy. Thank you to George J for the followup email within 24 hours of delivery. 343053

Ordered lots of parts on Monday, received most of them by Thursday. The received parts were well packaged and undamaged. A few of the parts they didn't have in stock so they had those drop-shipped to me which should be delivered in the next couple of days. No supplier I have ordered any parts from has such a great technical reference web site or personal customer support. Yea, Rebecca - Well Done! Yes, I'm very happy with the pricing. Thanks for your great support and I look forward to doing business with them again. More info to follow as soon as I can get the parts installed on my trailer. 326670

Nuts and bolts are nuts and bolts but I can report that the self-adjusting brakes have worked well on our two-thousand mile trip this summer through the mountains of Utah, Idaho, Nevada, Oregon and Washington. They stop straight and true and don't seem to fade on those long down grades like the infamous "Cabbage Hill" near Pendelton Or. 306927

Just received my order of new backing plate assemblies and some misc small parts. Ordered on line late Sunday night, confirmed I had ordered the right parts Monday morning before shipment went out. Customer service by phone was superb and the gal I talked with was perfect. Shipment was on my porch Friday afternoon. I did open box and inspect shipment that arrived completely intact/good shape and all looked good at this point. Not sure when will get to the brakes on the trailer but will post again when the job is done. So far nothing but good to say about Etrailer.com. Regards, John. 300454

Bought these bolts just in case and was glad I did. Turns out, my backing plates had fixed studs rather than bolts, but having these on hand made reassembly a snap. Threads matched the nuts perfectly. Highly recommend. 140088

  • How to Order Dexter 6k Axle with Brakes 7461121 with Self Adjusting Brakes
    The brakes that come with the Dexter Axle part # 7461121-EB are manual adjust brakes part numbers # 23-106 and # 23-105. To order a similar setup with self-adjusting brakes is possible but you will need to piece the kit together as we don't have it all as one part number. You'd need the following: # 7461121 # 8-201-9UC3-EZ quantity 2 # 23-458-459 # 7-5

  • Recommended Brake Assemblies and Hubs with Oil Bath For Dexter 8,000 lb Axles
    For your 8,000 lb axle hubs with oil bath, I recommend the Trailer Hub and Drum Assembly - 8,000-lb Axles - 8 on 6-1/2 - Oil Bath, # 8-285-10UC3-A. The brake assemblies I recommend to match the hubs are the Electric Trailer Brake with Dust Shield - Self-Adjusting - 12-1/4" - Left Hand - 8,000 lbs # AKEBRK-8L and # AKEBRK-8R for the right hand side. You may want the Brake Adjustment Spoon for Drum Brakes # W80630 for the initial adjustment, but these brakes with self-adjust after that. If...

  • Recommended Brake Assembly 12x2 with 4 Bolt Mounting Pattern
    For your 12x2 electric brake assemblies, I recommend the Dexter Electric Brake Kit for 4 Bolt or 5 Bolt Flange - 12" - Left/Right Hand Assemblies # 23-105-106-09. These assemblies will fit your 4 bolt flange and will work well on your trailer. The mounting nuts are included but the bolts are not. If you need the bolts and lockwashers, I recommend # 7-5 and # 38LW. You may also want the brake adjustment tool # W80630 to install and maintain your brakes.

  • Will Dexter Brake Assemblies Fit on a Lippert Axle
    You will have no problem using a Dexter brake assembly on a Lippert 7K axle. We have installed several Dexter brake assemblies on Lippert axles at our shop. Lippert and Dexter use the same standard mounting pattern and brake sizes. If you want standard brake assemblies, you could go with the Right Hand brake # 23-181 and the Left Hand brake # 23-180. I recommend stepping up to the Dexter Nev-R-Adjust brakes, # 23-465 and # 23-464. The cost difference is very minimal compared to the standard...

  • Recommended Brake Assemblies For Dexter Axle 3500 lb And 5200 lb
    I reached out the the manufacturer and found that they have two possible axles that meet that criteria. One is definitely more likely your application than the other, but I will give you both brake assembly options. For a 3500 lb axle, you will want the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA. This will give you both the left and right assemblies. There is a sticker to help you with which assembly fits which side....

  • Selecting Correct Replacement 12 x 2 Electric Brake and Drum Assembly for 6000-lb Axle
    The best way to identify the correct replacement components for your trailer is by using the part numbers from your current inner and outer bearings and grease seals (or a spindle measurement where the seal and bearings ride). It is possible to measure the spindles to obtain grease seal dimensions (location B on the photo) but this process requires care and a precision digital caliper like # PTW80157. You will also need to confirm the diameter of your wheel studs. We already know your brakes...

  • Replacement Dexter 6K Electric Trailer Drum Brakes
    To replace your Dexter right-hand 6K electric drum brake 023-358-00 you can use part # 23-106-09. For a left-hand brake use part # 23-105-09. If you decide to replace both left and right brakes we offer both in a set as part # 23-105-106-09. These brakes fit both 4-bolt and 5-bolt brake mounting flanges. If you need mounting hardware you can use bolt # 7-5, lock washer # 38LW and nut # 38N.

  • Brake Flange Mounting Bolt Recommendation for Kodiak Disk Brake Kit K2R526D
    The brake flange mounting bolts are not included with the Kodiak Disc Brake Kit # K2R526D that you referenced. If you need bolts you would want the part # 7-5 for the bolt, part # 38LW for the washer and part # 38N for the nut. These aren't stainless, but they will still work fine. If you wanted to go with stainless you would have to source them at a hardware store.

  • Availability of Old Round-Style Brake Magnets for Hayes 12 x 2 Electric Brakes
    If your trailer has pre-1988 Hayes electric brakes that use the round-style magnets you will have to replace the entire brake assembly. Until a few years ago the old-style round magnets were still available as replacement parts but they are no longer offered. It will therefore be necessary to update your trailer with new brake assemblies. In your case you will also need to replace your hubs/drums in order to use these new brake assemblies. Replacement hubs/drums need to be matched based...

    The electric brakes I recommend to use with the Trailer Hub/Drum, part # 8-219-50 and the Timbren Heavy-Duty Axle-Less Trailer Suspension, part # ASR35HDS02 is the Dexter 12 inch Nev-R-Adjust Electric Brake Assembly, part # 23-459 for the right hand side. For the left hand I recommend part # 23-458. The mounting hardware for the brake systems is not included. You will need part # 38LW, part # 38N, and part # 7-5. For each brake you will need 5 of each.

  • Replacement Hydraulic Brake Assemblies and Drums with 008-201-09 Casting Number for Boat Trailer
    The 008-201-09 number you provided comes back on a Dexter Axle hub that we offer as part # 8-201-9UC3-EZ, a 12 x 2 inch brake drum. This hub uses a 25580 inner and 15123 outer bearing, so please check the reference numbers on your existing bearings to confirm that this hub is compatible. These hubs use a grease seal with a 2-1/8 inch inner diameter. Since it's kind of difficult to measure the inner diameter of a used grease seal, measure the OD of the spindle where the grease seal rides....

  • Does Dexter 12 Inch Electric Trailer Brake Assembly # 23-181 Include the Mounting Hardware
    The replacement right-hand brake assembly you referenced, part # 23-181 does not include the mounting hardware. You'll need 5 of the # 38N nuts and 5 of the # 7-5 bolts. Something else to be aware of, some time ago Dexter stopped including the mud and crud plugs that cover the brake adjuster holes. We offer them as part # BP10-220 for 4 plugs.

    I walked out to the warehouse to look at the Electric Brake Assembly for 6K Axles, part # 23-459. The brake assembly does not include the backing plate bolts. I would recommend installing new bolts and nuts for easier installation and safety. For mounting bolt, you would need Brake Mounting Bolt, part # 7-5, which is sold as a quantity of 1. For mounting nuts, you would need Nut for Brake Mounting Bolt, part # 38N, which is also sold in quantity of 1. You will also want to use Lockwasher...

You will need one set for each of your 3 axles. If you need the mounting hardware the Brake Mounting Bolt for 12" Brake Assembly # 7-5 and lockwasher # 38LW along with nut # 38N are what you will need. For your bushings you will want the Two Piece Nylon Bushing - Qty 4 # SP05-080.

    For Made in America 12 x 2-inch electric drum brakes for your 2003 Mobile Suites trailer with tandem 7K axles I recommend the Dexter kit # 23-464-465 for each axle if you want self-adjusting brakes. If you prefer standard manual-adjust brakes instead then use two of kit # 23-180-181. Either way you will want to order two kits to be able to fit new brakes on both axles. For mounting hardware you can use parts # 38LW, # 7-5 and # 38N (five of each per brake) and for a brake adjustment...

  • Replacing the Brakes on a 1966 Airstream Travel Trailer
    The Dexter Electric Trailer Brake Kit part # 23-112-113 is designed for 6,000 lb axles that use a 5 bolt brake mounting flange. They are compatible with 14.5" to 16" diameter wheels. As long as your trailer has these requirements then the brakes will work well for you. Unfortunately, we do not have information as to what braking assemblies your 1966 Airstream trailer came with therefore you will need to go out to your trailer and physically count the bolt holes on the brake flange and measure...

    To determine which brake assembly you need, measure the width of your brake linings, as shown in the photo I edited for you. If your existing brake shoes measure 4 inches wide, the # 23-438 you mentioned would be an example of a good replacement for you if your existing brake assemblies use 7 mounting bolts (some use 4) and the diameter of the assembly is 12-1/4 inches in diameter when measured from the outside of one brake shoe directly across to the outside of the other shoe as shown...

The brake assembly you referenced is just the left hand side and the right hand side is the Dexter Electric Brake Assembly # 23-106-09 or they can be purchased together as part # 23-105-106-09.

    Since the ProLube kit # XLPROLUBE2440KIT is only rated for use on 5,200 to 6,000 pound axles I do not recommend using it for 7,000 pound axles. Grease would be better for marine applications since a hub full of grease repels water and an oil bath hub could just let the water set on top. The correct grease seal for disc brake kit # K2HR712D is # RG06-070. It does have an inner diameter of 2.25 inches and the outer diameter at 3.376 inches will fit the hub in the disc brake kit.

    From my research it looks like you have 6,000 lb axles on your trailer. You may want to check to see if there is a plate or sticker that shows the axle weight capacity. If you have a 5-bolt brake mounting flange I recommend the Dexter Nev-R-Adjust Electric Brake Assembly, part # 23-459 for the right hand and part # 23-458 for the left hand. These are designed to use with 12 inch hubs and drums. I have attached links to a product review video and an initial setup video for these brakes....
