Misc brake questions
I'm about to remove my calipers to refinish them and to replace rotors. A few quick questions:
1. after you remove the little Phillips head screws that hold the rotor to the stub axle, do you replace them or just leave them off?
2. how do you plug/cap the brake lines so the MC doesn't drain?
3. the manual and writeups seem to speak of replacing the caliper bolts in the front; replace the rear ones too?

The screws simply hold the rotor in place when the wheel is off. No harm if they are not there but if you have new or didn't trash the originals why not replace them.
There are line clamp pliers that go on the flex hose. You can get some DIN caps nuts that thread on to the fitting, seat on the line bubble flare or you can use the little rubber bleeder cap found on older 911 bleeders which pop on the line. Maybe it is time for a fluid change anyway ?
The front bolts are stretch bolts and yes they should be replaced. The rear bolts are in shear and don't tighten in the same dynamic. So it is not mandatory but there is no harm for the couple of bucks to have fresh hardware on a four corners.
