Hi everyone. Steven here with etrailer.com. Today we're looking together at a replacement master cylinder assembly, specifically for the Dexter Model 60 and the Arrow 7,500 brake actuators for drum brakes. Now folks, as I just mentioned, the two models, this works for the Dexter model 60 and the Arrow 7,500. Drum brakes only, you're gonna get the master cylinder. You've already got the gasket, the top plate, the screw on caps included.
All the bolts here wouldn't need to be tightened down. They're just kinda loosely fit there. And then you'll obviously, you'll put your brake fluid in there and then your cap will just go back on obviously, and just gotta get lined up here. There we go. And then you've got your brake line connector here, and then you've got the boot over here for the rod assembly and everything.
So very easy direct replacement part to work, again, for those Dexter Model 60 and Arrow 7,500. Now it does come with the lock washer, like I said, those kind of things. The gasket, all the bolts and everything you need. So what you see is what you're getting. Very nice, well made product.
This again is a replacement master cylinder assembly. I'm Steven, thanks for watching.

Worked great to replace my Dico 60.
This was the best price I could find.
I ordered it on Monday and got in the following Saturday.
Installation was quick and painless.
My only complaint is I had to ask for a tracking number. However, they responded to my email very quickly providing the tracking.
Exact replacement for my trailer’s surge brakes. Tracking the shipment was interesting. Took a while from order date to ship date but it was worth it. I would do it again.
A bit bigger than the Dico it replaced (exact manufacturer and part number, go figure). Had to give the tongue some encouragement to get the new part to fit (certainly not etrailer's fault). Would have liked torque specs for cover.
etrailer was fantastic. Will definitely use again. Ordered on a Saturday, received ship notification on Sunday and part delivered on Tuesday. Unheard of - thanks George!
Etrailer transaction was easy and the shock and master cylinder arrived fast. The m/c installed without any mods and now my boat trailer is a dream to tow.
Exactly what I expected. Looking nice. Packed nice. Want to install it later today.
I purchased master cylinder for a Titan model 60 and was easy to purchase from etrailer and i received it in the amount of time that was on the order. everything that was needed was included to change the part. I rate etrailer excellent because the order was easy and i received the part with no problems. The master cylinder was the exact part as the original
This is the direct replacement for my Titan hitch. It appears to have an anodized exterior coating that should resist rust.
Brakes were rebuilt with etrailer parts and are working great. Thanks // etrailer.

Still performing great
There was a loud clunk and you could feel it when using the surge brakes on our ski boat trailer. The master cylinder was badly pitted. Now the braking is smooth and responsive.
I ordered the brake actuator replacement for the Titan Model 60, paid extra for the UPS ground shipping and had the part in 6 days! You must take apart the brake actuator from the hitch as not to damage the gasket when installing the part. Had it installed in 15 minutes. Another 15 to bleed the drum brakes and all is well.

I don't like to give bad reviews, but I want to share so others don't experience what I did. I don't know what happened on this one on my car hauler flat bed trailer. I installed it and filled it with brake fluid, and bled the lines and pressure tested and pulled it around town for a test run, all was good. By the time I took a trip with my trailer one year later in August, 2025, all of the fluid was gone, no signs of fluid leaks anywhere on the trailer frame or concrete below it, maybe it evaporated in the TX heat? It was rusted inside, I refilled it as is and had to take my trip. Within 200 miles, one of the brakes locked up and was over heating the hub and was smoking hot, we were lucky catch it. I loosened the line at the back of the master cylinder, and the fluid released in the line and the brake immediately released, I'm sure the master cylinder was plugged. I completed the remaining 1,200 miles of the trip without trailer brakes. I am frustrated that a new unit would loosed its fluid and rust with barely any use of the system. And of

I am sorry to hear about your experience with this master cylinder. I am not sure exactly what caused that but I do know if a trailer sits for a long period of time is can rust or corrode. There is a chance the original master cylinder was faulty, or there was a damaged wheel cylinder inside the brake drum itself. Have you used it at all since your trip?
This was exactly as described in the subscription. It was simple to remove the old and add in this new one. I was surprised by the quick shipping as well.

Still working as expected after a year.
I needed this part to replace a rusted and blocked cylinder on a boat trailer. The part was delivered earlier than I expected and was exactly what I needed. The price was right and the service was superb.

Made the trailer connection like new. Have had zero problems with the brake assembly
The master cylinder I reicieved is as good as anywhere else plus etrailer was the cheapest and fast delivery. Will do business with again.

all the trailer parts i got were the best quality and the best price i could find. thanks for the great site to keep my trailer on the road.
Quick delivery, excellent customer service and great prices, as usual.
When I installed the Brake Fluid Master Cylinder reservoir on the coupler. It was a bit oversized in height. Finally was able to bolt on. Then when I was screwing in the four top bolts to hold the reservoir in place, one of the bolts snapped off in the housing. It will have to be extruded somehow.
Brake lines - no problem.

Quick shipping and exactly what I ordered and expected. Thank you.
Good product at a good price. Got it installed and the system bled (the old brake fluid looked like thin mud coming out!) and everything works well. Install was easy, with the exception that the old master cylinder that I removed looks to have been just a hair shorter than this one that I got from etrailer. The new one was a tiny bit too tall for it to slide in the back of the actuator. I ended up removing the actuator from the tongue of the trailer to get the master cylinder bolted onto it. With the four master cylinder bolts torqued down it fit fine and the actuator easily went back into place on the tongue.
I do wish it had a metal cap like the old one that it replaced, but that is not a huge deal. I hope the plastic one holds up.

The plastic master cylinder cap seems to leak. Other than that, its fine.
quick shipping. easy to use site.
Perfect replacement for my trailer with surge brakes.
Perfect fit and best price out there. Was delivered faster then my prime membership would have. Easy install and (thanks to etrailer) have a whole new braking system under my Outlaw.
Thanks Steven & etrailer for listening and your expert follow up!!
This one required a little bit of modification I had to have some welding done. This is a little bit taller of a unit that I had so I had to have the top cut off of my housing and re-welded another additional $250 but the part worked great.
part didn't fit.
This fit my Trailer Aluminum car trailer fine, and is an exact replacement to the Titan 60. I really only needed a rebuild kit, but seems no such kit is available for this master cylinder.
Great Service and prompt shipping!
