| Post subject: | Trailer Brakes (surge) |
i have a 2000 190 horizon with the dual axle trailer. i started to notice my trailer brakes weren't working very well, if at all. i opened the master cylinder res on the tounge to find rusted out fluid. i sucked it all out as well as some rust flakes and got it good and clean. now i still feel the same with the surge brakes not working. feels like the truck is stopping everything. how can i bleed surge brakes on this trailer? any ideas? any thoughts? thanks all! |

You may have sucked everything out of the master cylinder, but your lines & calipers (or wheel cylinders) are still full of junk. Even at that, if you're getting no braking action at all on the trailer, I suspect that isn't your only problem. It may be time to pull the calipers or drums, clean & lube everything, replace the wheel cylinders if you have drums, and flush new fluid through the system. |

is there any trick to bleeding the system? like maybe back into a curb stop or something to get the actuator to brake? thanks 230 mike! |

Not sure what you emergency stop looks like (the small cable that actuates the brakes in case the trailer comes disconnected), but I used that on mine to pump the master cylinder to bleed my brakes this spring. |

I've tripped that before when dropping it off at the shop but told them and they said leave it they'd handle it before moving it. do you just tap it back into the upright position when done? thanks! |

Just open the bleeder screws and gravity bleed them,just keep adding fluid till all air is out and fluid runs fairly clean. |

And if you wind up have to replace parts or all of the system... http://www.championtrailers.com/techsup.html#techretro |

+1 on Champion Trailers - great people to deal with even when you are on the other side of the world. Would definately recommend them to anyone looking for trailer parts. There is also eTrailer who are very good, but only ship to the US. |

There is a device you can get at the auto parts store. It's a vacuum brake bleeding kit. Basically, there is a hand pump to make a suction, and you connect the hoses to the bleed nipples at the wheels. You can get the whole kit for about $20, including the connector adapters you need. It's the easiest, cleanest, most complete way to bleed brakes. It'll make this job much easier. |

I like those self-bleeders, but quite a few people (myself included) have found that they don't work as well as having someone pump the actuator. Too bad, because it would be nice to be able to do it alone. I'm not trying to discourage anyone from trying it; for those it works for, it would be a great tool. |

I think sometimes the suction bleeders may not work because air acutally gets into the master cyl itself and it cant get easily pulled all the way to the wheel cyl or caliper...I use the one man bleeder made by Lisle that has a small cup with a cap and a line that goes into it...you fill it about half full with fluid and then hook it up to the bleeder...pump the actuator till you don't see bubbles any more...it may overflow and make a bit of a mess but it does get the air out...try to keep the bleeder device higher than the cylinder or caliper...this helps getting the air bubbles out... |

I just bled my trailer brakes 2 weeks ago. I had the vacuum bleeder pump but found it very slow. Also, when loosening the brake bleeder screws, one of the hex rounded. So went to the auto parts store to get new bleeder screws. Found they had "self bleeder" screws which have a check valve in them. Installs like a normal one, but when you want to bleed the brakes just back if off half turn and then I manually pushed the actuator on the trailer tongue. The check valve lets the fluid/air out but doesn't let air back in. I used a short piece of tubing into a bottle to catch the old fluid. When done I just tightened the screw back in like normal. Seemed to work fine. They cost a lot more (~$11) than the standard part ($4) but made it much easier. |

That's pure genius. I'll be looking for those the next time I have to do any brake maintenance. |
