Replace old pads with new, and reverse the above process.
For brake lines, only re-install the calipers, leave the car up on jacks and start with the removal of the lines. Front lines have a fender bracket that retains the line.
Loosen the 10mm nut, "NOT" the fender bolt, of the metal line to the bracket and drain brake fluid.
Now remove the 10mm bolt holding the line to the caliper.
Now remove the fender bracket bolt. It's a 10mm as well, and the line will be completely free.
Replace and reverse steps with aftermarket line.
Note: When purchasing any aftermarket brake lines, make sure that they are supplied with the fender bracket. DO NOT PURCHASE any kits that DO NOT have this bracket, as the line may rub against the tire.
