brake line replacement.

Have a full set of stainless brake line replacements to fit, if i keep the reservoir cap on can i fit each one seperately and bleed without screwing anything up or just remove everything and do one full bleed at the end?

Leaving the cap on will not keep air from getting in or prevent fluid loss, though it may help to slow it down. If it were me, I would replace one line at a time, bleed, and move on to the next. I would also be sure to refill the reservoir in between and be sure not to let it run dry. I think this will make for easier bleeding in the long run.

Where did you source your lines from? I need to order a set for my daughter's XJ.

Do you have ABS you're connecting the new lines to? That's the part you don't want to get air in or you'll have to take it somewhere to have it bled out with a DRB scan tool.

I have bulk poly-coated roll line and need to replace all my lines too. Believe I'm going to try and find something to plug the ABS ports with so the fluid doesn't all run out and get air in the system. Even thought about just cutting/crimping the lines near the unit since I'm going to have to run new lines anyhow. But then I would have to find new metric fitting to go into the ABS ports. They do make an adapter so you can use the fitting which come on pre-made lines. I'm also going to keep the fluid reservoir filled and someone posted to put a piece of saran wrap under the cap to help seal it. Not sure if that works or not. Good luck.

yeah got the stock 9er (well untouched ABS). Was thinking about some kitchen wrap etc under the cap so it acted like in the same manner as a finger over the end of a straw to stop the juice coming out ........ if you know what i mean

Yeah, Saran wrap which I mentioned for under the cap is just a brand of plastic kitchen wrap here. Regardless what it's called which side of the pond you're on we're on the same page as far a creating a liquid vacuum like a straw.

I've heard you don't necessarily get air in the ABS HCU (hydraulic control unit) by disconnecting the lines going to the different brake locations but it's the lines between the master cylinder and ABS you don't want to go dry/let air in.
