Most Popular Roadmaster for Cadillac SRX

Just what I needed.

Was required to make the MM brake monitor light work. Kit fit perfectly and is functioning as designed. Not an easy install in my SS and adjustment is very sensitive but works fine when tuned in.

The product shipped on time and has been worry free. etrailer gets 5 stars for customer service every time I order from them.

This braking system does what it's suppose to do, smooth proportional braking between motorhome air brakes and the tow vehicle. The only reason I did not rate at 5 stars is that there is a slight misalignment of air cylinder mounting bracket and 2022 Jeep Gladiator brake pedal.

The braking system and the lights are working, one year after I bought them. However, I am towing a 2016 Keep Patriot, and about 2_500 miles after install, the system started making an annoying clicking noise when I enter the Patriot, which stops after about 10 seconds and then starts up again, usually a minute or so later, for another 10 or 15 seconds. etrailer first said that they had never heard of.such a thing, then said that there are otherwise comments for Keep Patriot owners on forums. Still have no.fix. Also, at first I did not know that to store the tow bar, it must be pulled up so that the post fitting can moe to the position where it fits into the hole.in the smaii yellow bracket, which works well when used correctly. And store the coiled.wide in your tower vehicle.to prevent corrosion which will interfere with its function.

Invisibrake on a 2014 Honda CRV I’ve been a carpenter all my life and recently finished building a custom car. After Watching the etrailer video (multiple times) it appeared to be a fairly simple installation, not so much, as getting up under the dash is very tight, mounting locations and access points are different and not much working room under dash. 1. It appears the length of the cable and air cylinder are shorter than when the video was made, so an alternate location for the cable clamp is needed. The cable direction needed to be at a 90’ angle to the pedal. . Removing all the carpet and insulation was a PIA to get a direct connection to metal. The cylinder mounted a few inches closer than the video showed and I used two clamps to attach it. The mounting point on the cable clamp ending up being behind the wheel well, so I used a couple of stainless steel bolts for attachment. 2. The hole location into the firewall was very difficult to get to. I was only able to drill a 5/8” hole. I couldn’t get my step bit in there and the brake lines are on the outside and didn’t want to risk damaging them. I just ran the power wires and vacuum line through this hole. I drilled another 3/4” hole in the floor at the back of the cylinder. I ran the plug for brake away and the lighting wires under the body and followed the lighting wires from the back to front. Covering all wires in a plastic loom 3. The plastic molding pieces required some trimming to fit the new wires and cylinder. 4. The video shows the box mounting directly though the removable carpet mat. (Not a good thing) I removed the mat prior to install and will have to modify it to reinstall. 5. All the wiring in the engine compartment and the plug was fairly straight forward and simple. It all appear to work as it should. Testing seemed to work good. I recommend making a new installation video. When I ordered it, the Amazon price was lower and etrailer couldn’t match the pricing. Two weeks later the pricing dropped to match the amazon price ( lower by $150). Sad face.. 2014 CRV Baseplate -Roadmaster 521567-5 The installation was fairly simple and the video explained it well. The bumper and grille were fairly difficult to remove and expect to break some of the clips. ( new yellow ones can be purchased on Amazon) . I would wait to replace the grille until all the plug wiring is complete. Just hind site. 2014 Honda CRV Brake switch relay. -Roadmaster 88400 Relay switch are really simple to install, but the location of the brake switch and the small wires made it really difficult. But it works as it should

Evidently Roadmaster had made some slight alterations from the depiction, for the better. The fuse wiring was a spade end with two fuse holders built in. The holder closest to the spades was for the original circuit and the other for the new circuit. This was very handy. I had watched the installation video and thought it would be fairly easy; therefore I attached the terminals to the green, black, and white wires before even going to the CR-V. I did however purchase different spade connectors as I thought I may want to remove the brake relay switch in the future for another vehicle should I trade. Also the yellow connector is quite large and the video showed bending the wire over itself so that it would hold on the smaller wires. This was a wise decision. What was the problem was the wiring in my CR-V. The video showed similar size wiring from the brake switch. What I found was smaller wire, loomed very close to the brake switch. Evidently Honda had made some modifications. I believe the wire was 22 gauge and there was no real way the blue or yellow connectors would have worked. That said, after disconnecting from the switch, stripping the loom back to get some exposed wiring, cutting and using the 22-16 gauge connectors, drilling a hole for the ground screw, etc. the switch worked perfectly. I did vary the fuse location from the 7.5 Amp #29 Occupant Detection System (ODS) to the 15 Amp #28 Washer as I figured it would less likely interfere with any operation.

So I never used mine. This is for those trying to decide if they need one. I tow an F250 with a 43’ tag axle, with an 8.9l Cummings. Yes I can feel the truck back there but I have never had the need for additional braking. Crossing the Snoqualmie pass on I-90 or driving through the cascades, I have no problems slowing with the engine brake. I have a big rig and tow a big truck so if this is your set up I’d give it a shot before committing to such an expensive item that I never use. I’m sure smaller rigs pulling larger trucks will benefit from a device like this.

Ordering was easy. Delivered very promptly. Actually cheaper then what the manufacturer sells it for. Live near manufacturer and having them install all my flat towing components this month. Great service Etrailer!!

Kit fits great! Hooked up a 2004 Workhorse to a 2002 Jeep Liberty. It might be preferable to be handy with some advanced mechanical skills and tools to install this efficiently. Directions are great but you do need to figure out your own locations for certain items like the break-away reservoir, compressor, routing lines and wires out of harms way, but not bad at all. Parts are great, everything there but added a couple different wiring splices of my own.

Your customer service leaves nothing lacking, and this follow-up from you is so out of character for the many web sites I have purchased from over the years. I am impressed by you and your company. I bought the tow bar and the brake system for my Equinox, and installed them my self (I am 70 years old) - and with your provided instructions and video, I had no problems (even though I was surprised by the number of parts and detail that went into the assemblies). Both systems have worked very well, with no problems. I am completely satisfied with them, and have told my friends and traveling acquaintances about your company. Thanks for your follow-up!
