Default Is there a trick for disconnecting the brake lines?

Last year when I replaced the control arms, I noticed that the rubber housings on both front brake lines were cracked.

Fast forward and I did a rotor & pads service yesterday. Tried to replace the brake lines also (the rubber lines connected to the calipers) but the 10mm nuts connecting the metal lines to the rubber hoses were seized.

I PB Blast'ed the nuts and tried again, but it felt like I was going to snap the metal lines so I stopped.

Is there a trick to removing the 10mm brake line nuts? There are metal spacer clips, but it looks like you have to remove the lines before those release.

make sure your also holding the rubber line with an open end so its not flexing on you.

The bleed nipples on mine are 11mm but the lines are 10mm. I'll give it the torch.

torch then spray with water until it stops sizzling then torch and cry to crack. also try back and forth, tighten a little then loosen a little. what year do you have? i had to make an 11mm flare wrench for mine, its interesting yours is 10mm that would have made my life easier

If you're going to be hitting them with the torch, I would consider going to your local Walmart (or whatever you have) and dripping some paraffin wax on it. I use it for seized nuts/bolts all the time and it works FANTASTICALLY

Yea its a love it or hate it type of thing. It doesnt work all the time, but when ive needed it to, its worked wonders on exhaust studs. when you heat up the area the metal expands, but we all know that. Take a piece of paraffin wax (candle wax), I prefer a long, thinner piece because its easier to maneuver into other places. Heat up the bolt/nut that your are trying to free-up and touch the wax to the threads leading into the fastener. It doesnt have to be super hot just hot enough to melt the wax. The beauty of Paraffin is that it is attracted to the heat, so if you apply heat more towards the bottom of the fastener it will pull the wax into the threads. Let it cool, and then try to loosen it up. Its not guaranteed, but sometimes its a life saver.

Did you get them off? I've always had good luck with heating them a torch and then using a spray bottle filled with water. Repeat several times for extra rusty parts. Make sure to get it good and hot.

I went for a test drive and had a leak from the brake line/brake hose connection on the driver's side front. I tightened the crap out of it and it's not leaking anymore. So... I'm going to wait until this weekend and give it another try.

I suspect heat will get the nuts to turn and I'm going to try the paraffin trick.

Hoping I didn't knacker the brake line.
