I swore I read in a thread here that someone had found a replacement connector/link that goes between the two cables that operate the diff mounted e-brake on the newer IC's.
I have read through threads till my eyes hurt and can't find who posted it.
I think one of my pumps has lost prime. Brake pressure light on dash is on. I get a loaded pump noise then after it pressures up I still have a whirling noise that reminds me of just the motor turning with no load. I am going to have to cut a cable or the connector to get a bus in the shop and would much rather it be the connector.
Any help is greatly appreciated!!! |

The replacement connector comes with a new cable, but there should be some alternatives to cutting it. First off, do you have the Meritor brake software? If so, have you tried to release the parking brake with the laptop? If that's not an option, you can either release tension by turning the star adjuster on the drum in reverse, or possibly by unscrewing the brake cable out of the motor on the frame rail. |

you shouldn't try backing off any of the cables . They are under a lot of pressure from the hydraulic pump . If you do try and back them off . They just keep adding tension .There are a couple sensors on the master cylinder that control the brakes . I have seen the sensor switch on the bottom off the master get rusty and jammed up . Try cleaning that. |

Please look at the GM cable connector # 15714661, I believe that will work for you, around $3.00 earl |

There is only tension on the cables when the brake is engaged. Its a lot and you will rip the threads out of the end of the sahr can if you try to unscrew it . Ive changed dozens of those cables from corrosion and just remove and save the old connectors when we replace them. Just a tip when replacing a cable just go ahead and replace the shoes,adjusters,both cables. Most all of that stuff will all be bad or soon to be bad at the same time. |

I ordered a set of connectors for GM products Dorman Help #21126 and the larger "U" shaped connector seems to be doing the job. For less than 3 dollars it was a gamble that paid off.
I can't say for sure that this is the one I used out of the kit but if so it is sold by itself as Dorman 484-223 C-Style Brake Cable Connector.
Hope this helps someone else as we shouldn't have to buy a high dollar cable when all that is needed is a 3 dollar connector. Ugh!!! |

I don't have the Meritor software.. Only option I have found is to separate the connector to get it off the city street or county road or in the shop from the lot. |

I think it is the tubular one (like the OEM one)in the kit I ordered mentioned below but it is to small in diameter to work with the cables.
Thanks though!! |
