MG MGB Technical - Clutch Slave cylinder
|We are trying to bleed the slave cylinder but can't get the bleeder to open.|
Have been spraying it with PB Blaster but was wondering can we apply heat to it or should it just be soaked?

|Sorry the car is a 1972 MGB. I'm not sure how to edit the post.|
|You can certainly apply heat to the cylinder adjacent to the nipple but you may damage the internal piston seal. I think I'd persevere a bit longer with PB Blaster before going for the heat otherwise you may just have to fit a new seal kit as well.|
|When I need local heat, I hold a 40w solderering iron on for a few minutes.|
|No matter which method you use to break the rust try shocking it. With a socket and bar on the bleeder screw rap the end of the bar repeatedly with a mallet or your hand. I like to attempt to tighten it slightly first before loosening it. I have never had one that would not loosen using this method. If you just plain pull on the bar the bleeder may break off. |
Just wanted to get back band let you knowShaun got the bleeder loose last nite while I was at work. He followed all of the above suggestions. We havePB Blasted for about 5 days , tried moving with a quarter inch deep socket. He heated with a commercial soldering iron, tapped with a hammer, and then used an adapted breaker bar it moved and he reduced to the 1/4 drive to get it out. I am now going to look at it and see the leak he found.
