Video Transcript for Redline Trailer Brakes BP17-030 Review

Speaker 1: Today we're gonna take a look at the replacement left hand uni Servo wheel cylinder for 10 inch and 12 inch brake assemblies. This will replace the hydraulic wheel cylinder on the left hand side of the 10 inch and 12 inch brake assemblies that are manufactured by Dexter, Bendix, Dico, Demco, and Atwood. This wheel cylinder is for the left hand configuration, so the driver's side. It is a uni Servo, which means it's a single plunger design, and it does have a nice sink plating to it to help resist corrosion. This part is made in the USA. That should do it for the replacement left hand uni Servo wheel cylinder for 10 inch and 12 inch brake assemblies..

by:

Thought part would be cast iron like the old one. Not sure what material it's made of. No instructions on recommended torque for brake line nut and bleeder. It matches old one and does fit into backing plate. Will see what happens 510137

Our mechanical staff decided to replace the wheel cylinders rather than the complete assemblies. The cylinders are nice quality at least as good as OEM. They arrived well packed and a day before expected. The staff at etrailer.com were great from start to finish. George J was helpful with the placement of the order and letting me know through emails on the progress of the order. When it comes to getting invoices for our finance department, one call to Preston M. and I have then in my email before I even hang up the phone! It is an absolute pleasure doing business with etrailer.com, so many businesses I do business with throughout the day don't have their level of customer service anymore! 497852

Perfect fit 409173



- BP17-030
by:

The brakes were "supposed" to be in working order when I bought the trailer, but I found that both wheel cylinders were rusted and frozen. These new wheel cylinders were an exact fit for my Venture boat trailer, which made for a nice easy installation!! I added a bit of thread anti-seize to the threads of the bolts, brake line, and bleeder threads to ensure that corrosion doesn't make them impossible to loosen. (Suggestion: When buying a used boat trailer, bring a floor jack and test the brakes before you buy!!) 404209

I live in BC Canada and spent weeks looking for trailer brake parts, what I thought was going to be a quick and easy job turned into a nightmare. After trying many auto shops I finally found a wheel cylinder that looked like what I needed, except the brake line was too small and wouldn't fit. I then bought adapters...that didn't fit either! I searched online forums to get ideas on where to find parts and all I found was a common message..."if you live in Canada, good luck!" By this point I have a tandem boat trailer & boat, just purchased by the way, on blocks with no brakes and looks like I'll be replacing everything and spending a lot of money as the only option. Last Wednesday night I was searching websites and came across etrailer.com. I was shocked to see they had what I needed, I ordered 4 replacement cylinders and the next morning received a confirmation email that my order had been shipped. There was hope after all. On Monday early afternoon...they had arrived and they were the RIGHT PARTS!!! Everything went back together with no problems. I also received a followup email from George saying that he had been notified I received the parts. etrailer.com is now my go to site for all parts and I recommend them to anyone looking for parts...especially in Canada! Thanks Guys. 187263

I was having a tough time finding the replacement parts locally, so I looked on etralier.com's site. They not only had the exact parts I needed, but they delivered the parts to my home within two days of placing the order and I even placed the order on a Sunday afternoon. The customer service followup and communication was excellent. I will definitely be using etrailer.com again. 45876

A wheel cylinder is a wheel cylinder, this review is about the company that sold me the wheel cylinder. I had trouble finding a replacement locally and just happened upon etrailer via google. I'm always apprehensive when doing business with a company online, especially ones that I've never dealt with before. Let me tell you, I worried a lot about nothing. My transaction with etrailer.com was outstanding. The part look up, ordering process, shipping time and communications were all 100%+ I highly recommend this merchant. In fact off to buy some more parts from them right now :) 14845

Do you have a question about this Accessories and Part?


  • Compatibility of Parts for Military Trailer
  • The parts you listed will need to be compatible with what is on your M101A3 military trailer, rather than the trailer itself. For example, the Master Cylinder # 10614 and Replacement Shock Absorber # 1844-2 are for Toledo brake actuators; if that is what you have on your trailer, then these parts will work. The same is true of the Wheel Cylinder - RH # BP17-020 and LH # BP17-030; they are replacements for 10" and 12" single serve brake assemblies manufactured by Dexter, Bendix, Dico,...

  • Wheel Cylinder Needed for 10 Inch Dexter Hydraulic Brake Drum Assembly
  • Based on my research, the 36-94 backing plate is used on the Dexter Single Servo # 23-313, # 23-312 hydraulic brake assemblies. For a 10 inch brake, left hand side, you will want # BP17-030 Wheel Cylinder. For 10 inch brake, right hand side, you will want # BP17-020 Wheel Cylinder.

  • Replacement Brake Shoes And Wheel Cylinders For Mastercraft Boat Trailer
  • For your Mastercraft Boat Trailer, I recommend the Titan Hydraulic Brake Kit - Free Backing - Galphorite - 10" - Left/Right Hand - 3,750 lbs # T4423500-400. The complete assembly is often less expensive than replacing the individual components. If you want just the components you mentioned, I recommend the 10" X 2-1/4" Hydraulic Brake Shoe/Lining (One Wheel) # BP04-120 and the Wheel Cylinder - 10" and 12" Single Servo RH # BP17-020 in addition to the left hand # BP17-030.
