Replacing brake hoses and brake fluid flush

Hello,

My Goodridge brake hoses come in tomorrow, and I think I'm going to remove the stock hoses and install them tomorrow.

What I plan on doing is jack up one side of the Jeep (and chock the rears), remove wheel and tire, remove stock hose, replace with new hose. Top off the brake fluid. Then have someone help me bleed that one corner.

Then I will repeat this for the next three wheels.

Here's my question. Say I replace the right front corner first. I bleed it and it's all good. Then I replace the right rear corner next. There's no need for me to go back and bleed the right front corner again, right?

Best to do all four lines first. Just make sure you keep topping off the fluid.

Then bleed each starting with the furthest from the master cylinder and work up to the closest.

You can bleed with the tires mounted.

I only know this as I recent researched this as I plan to upgrade my lines in the near future.

You should be able to switch the lines out with the tires on. Just did the rear ones like that the other day. IMHO these lines are a great upgrade. Much better pedal feel. Let us know what you think.

When you are taking the rubber hoses off use vise grips on the rubber lines to minimize fluid loss.

It's no big deal for me to remove the wheels and jack her up. Will probably take 2 minutes per wheel; I got a pretty good electric impact gun.

My main concern was having to re-bleed a corner when doing another corner. Would that be necessary? I don't see how air from the right rear caliper (for example) could make its way to the right front caliper when I'm only disconnecting the brake hose. I shouldn't have to re-bleed the previous hoses, right?

I'll post up some pics of the hoses. Doubt I'll be able to tell much about pedal feel though. I haven't really driven her that much. I got these hoses because I don't want to jimmy-rig the brake hoses when doing my lift, and these hoses also came with brackets.

I would do it like Barmanvarn said, that's the easiest .
Little trick I heard to was to connect line to caliper take a syringe fill brake line then connect to hard line
That way min air in line when bleeding. I've never tried it though.

always bleed from furthest to closest.

passenger rear, driver rear, passenger front, driver front.

Do all the lines, then all the bleeding.

I dont think the JK's ABS system is as complicated as the one on my Camaro SS, but on that one I actually had to go to the dealer and have them hook up their computer to activate the ABS pump. It has a bleed mode where it will basically auto bleed the brakes. I bled them by hand(or I guess by foot) as good as I could, then went to the dealer and they used their computer method. But like I said, I dont think the JK system is nearly as complicated as the one on the new Camaro's.
