How do you loosen the brake fluid leads from the master cylinder?

Answer 1

First spray a little Penetrating fluid into join and junction where the petrol (metal) lines screw onto the petrol filter. I generally leave for a few hours !! then spray a little more just before undoing. Always try to undo the hardest to get to first. These joins are always very tight as they have a slight taper and bind up. Make sure you use a side spanner with a very neat fit and wide enough to catch onto the whole nut surface. I stress this because once damaged and burred, its hard to get service on the spanner. Then position spanner so you can hold it in one hand and give a quick belt to end of spanner with palm of other hand. !!! you have to sort of crack the bond quickly and usually they come fairly easy, but may take a few goes. Put some rags around to protect your knuckles and palm of your hand unless your really tough and like pain. If the spanner wont go on properly due to damaged nut!! you will have to try vice grips or take to a mechanic. Try to crack the joint quickly,i found trying to undo these petrol lines slowly with gradual force generally results in damage to the nut.I did mine 2 days ago ok in a few minutes.Make sure you screw threads back in accuratley or you can strip threads..its easier to put them back in if you undo the filter from the firewall to start nuts into holes then tighten down the fuel filter and tighten nuts off on the lines last. cheers Kiwi Craig
