    got some new brakelines for the front today, the part that goes from the bracket on the frame to the caliper. How do I need to put them on? Just unbolt the old ones and stick the new ones on, and then bleed the system really good? Doing an axle swap soon, so I'll do this then, and just have to bleed one time. Does this sound right? Any tips on bleeding the system? Thanks

    all u need to do is re the old ones and install the new ones in the same place as the old ones, u will need to bleed the whole braking system begining with the wheel furthest away from ur master cyl .including ur rear whl cyls aswell. most likel the bleed patern will be right rear, left rear, right front and then the left front .

    also make sure you have something to catch the brake fluid when you disconnect the line from the caliper. that stuff will go everywhere

    yeah and for safty wear glasses.
    on the front there should be there nipple type things on the wheel, above where the lines attach, loosen that, then have someone hit the brakes till the juice pops out, then tighten them

    Hey man. You have to remove a saftey clip from the rear of the bracket to get that OEM line off. Take a screw driver and tap on each side of the clip till it pops off or you can use pliers to get it off. Since you arent going to reuse the OEM lines just clamp them off with locking pliers. Remove the bolt holding the hose to the caliper. Locate your new axle and bolt it in. Connect the new line to the new axle and then go at the OEM line. Keep the cover on the fluid resivoure to keep it dripping and not gushing at you. When your ready to do the brake lines you wont have as much fluid loss and mess to deal with. Bleed from rear to front clockwise starting with the pass. side. This is what I have done and had no problems to this date.

    Now would be a good time to get the old fluid out of the reservoir and refill with fresh, BEFORE starting to bleed. By the time all the air is out, the lines will have fresh fluid in them and it'll be a low-buck brake system flush.
