Common problems with Wheel Cylinders ?
What are the most common problems that can go wrong
with wheel cylinders. One of the problems I know is they can leak, that way however you will know they leak because there will be fluid loss. If there is no fluid loss, what are other common problems to go wring with wheel cylinders. Thanks in advance Denny B |

They rust up and the piston will not move.
So that explains why one side of my rear brakes never wore......... Erich BTDT "Denny B" > wrote in message news > What are the most common problems that can go wrong > with wheel cylinders.

They can get pitted by rust deposits and can leak when seals get to that
spot. Honing cyclinder can clean up surface pits. Seals can leak after old age. Most just replace the entire cyclinder assy. Best to flush out and bleed old brake fluid once in awhile to keep the moisture out of fluid. |

I am tempted to replace the cylinders and really want to. The only problem is I am not sure if I can undo the 2 bolts that hold the cylinder to the backing plate, and also undo the hydraulic line nut that attaches to the cylinder. If I knew these were not rusted on, I would change the cylinders in a flash. Bleeding the system is no problem. Denny B |

Alternately, you could rebuild in situ (hone and install new seals.) However then you still will always be wondering if the hard line is OK. nate -- replace "fly" with "com" to reply. http://home.comcast.net/~njnagel |

Worst comes to worse, you can grind/ break the heads of the bolts off the
cylinder Then use new hardware with the new cylinder. My trick for getting tubing nuts off is this. First place a tubing wrench on the nut. Then take vise grips and close them over the wrench. The vise grips keep the wrench from flexing open as you bust the nut loose. Use big enough vise grips and you can prevent rounding off the nut.

It happened to me once where I rounded a tubing nut and had a heck of a time getting it off. This vice grip method should prevent that from haappening. Denny B > "Denny B" > wrote in messag> > > |

And I can tell you from personal experience that flare nut wrenches do "spread." nate -- replace "fly" with "com" to reply. http://home.comcast.net/~njnagel |
