I'm in the middle of changing my back brakes, and it's going well except, I can't get the wheel cylinder off. I unbolted it, and it's attached to the brake line, and I can't seem to undo that nut, or whatever it is. Is there a special tool required for this?

Any help would be appreciated, cause I'm without a vehicle until I get this done. I did a search, and didn't come up with anything on this issue.

 

Why are you pulling the wheel cylinder? Are you going to replace it?

 

Yes, I am going to put the 1-ton cylinders in.

 

That's the brake line. Plan on replacing it too. There's no special tool. It's just rusted solid.

 

If I end up having to replace the brake line, though, how do I detach it from the wheel cylinder?

 

If you are going to replace the line, just cut it as close to the flare nut on the cylinder as you can. They tend to rust up nicely, and hang on to the backing plate fairly tight. If you have to, Use a punch, and a hammer to knock his **** out of there.

 

So I would need a flare nut wrench to get it off. What size would I need? I have all the other tools I've needed, just need to go pick one of these up.

 

They are probably 3/8th, or 7/16ths. I use a regular open end wrench, and am generous with the chemicals.

 

Save the pieces. You can can get a line with the correct ends and close to the correct length and just play with the bends to make it work. It doesn't have to pretty.

 

But pretty is good...No?
