Most brakes also require a (break-in) period. Dexter says to get up to about 20-30 mph and use the manual override several times. They may also feel weak breaking because it is recommended to let the brakes (seat) into the hub for the first 200 miles and then readjust the brakes. It is likely you need to do both of these even if they properly adjusted the brakes.

Nearly every time we hear about someone with new brakes that are weak the issue is that they just aren't adjusted properly.

Check out the video I attached at the 4:25 mark for more info on adjusting the brakes.

Since the trailer was off of the ground it would not take much voltage to stop the wheels from spinning so they may be getting power but they may not be getting enough power due to a short or wiring issue. But 9 times out of 10 weak trailer brakes…

Do you by any chance mean 235/80-16 and 235/85-16? Because there isn't a 275 trailer tire size that I have seen. If so then the widths are the same between the two 235 sizes. The difference is overall diameter. The 235/80-16 is 30.9 inches in…

Hey Dan, The info you provided does tell us a bit about the axle but isn't enough to look up what components go with with it. With it being a 3,500lb axle it's probably a generic 3,500lb kit for the bearings and seals but I'd hate to not…

You are going to want either our Bearing Kit #BK2-100 or the Timken Kit #TMK52VR. Both of these kits will give you the inner/outer bearings and races along with a grease seal and cotter pin/D-washer for one hub. You always want to replace the race…

The easiest way to determine what spindle your trailer has is to use a dial or digital caliper like the part #PTW80157 to measure it where the bearings and grease seal ride. I attached a picture that shows where these measurements are. If where the…

Answer 8

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…

It sounds like you may not have wired everything like it should be, particularly the ground wires. Each brake assembly is going to need to have a pair of wires coming out of it, with both having ground wires that are attached to bare metal surfaces…

Even though I cannot comment specifically on the grease you used because I am not familiar with it, I can tell you the best grease for trailer bearings is a a grease with a rating of GC-LB, which just means it is made to withstand very high…

Answer 12

There are some common things you can check to determine what is causing the poor braking performance. First, you do not want the trailer brakes to lock up and skid. You want them to be at a point just under that. The resistance of 12-1/4 inch by…
