Use the small rubber plugs which come jammed in the new brake cylinders inlet to plug your brake lines once you've taken them off. Also make sure your master cylinder is full so you don't drain it down low enough to let air into the line. |

Use a flare nut (single hex) split ring spanner on the pipe nuts. An open ender will distort them. If you don't have a proper flare nut spanner, cut a slot in a 7/16" ring spanner with the anglegrinder and make one. Check the nut moves without twisting the pipe or you will bugger it. If rusted together, spray with WD40 and leave a while. Then work the nut to and for gently to undo. |

Instalation tool? I use a flat bladed screwdriver. Easy. Make sure you put the linings on correctly and the springs. |

Personally I'd hit it with wd-40 or similar 30min before I try to undo the nut if it's been on the car for a long time. Oh and you're a skirt for not coming on the run yesterday.

Always a good idea to take a few photos with the digital camera before disassembly. They might come in handy if you get stuck putting it back together. Pete |

A proper pipe spanner has a single hex inside it, this means it has six corners. A normal ringspanner has a double hex, this means it has 12 corners. A single hex will grip better and not round the corners on the nut as easily. But use what you can get. If the nut does not want to undo and you have already hit it with WD40 try to do the nut up a touch (and I mean only a touch) and then undo it. Sometimes the little nip up will allow it to undo.
WD40 is actually rubbish, there are much better things to use as penetrating oil like for instance penetrating oil! |

Morris is right. The old Penetrene in a tin was much better for rusty bits. Do they still make it?? |
