caliper questions

[EJP914]

Just finished rebuild of left front caliper. Works great, but have some questions:
After bleeding caliper, bleeder valve seeps a little fluid. Reluctant to really tighten down on it. Can I wrap the threads with teflon tape or will the brake fluid disolve the tape?
I kept the brake pedal slightly depressed during rebuild of caliper, but after bleeding, I can't get the pedal to be as stiff as it was. I thought I got all the air out. Maybe I need to do agan? Do I need to bleed ALL of the calipers and not just the left front?
Do these "one man brake bleeding" trigger type bleeding devices really work?
Unrelated question, thinking about buying Brad Mayeur longitudinal reinforcement panels. What can I expect to pay to have these welded on? Ballpark number. Thanks in advance for all replies.

Teflon tape will not dissolve. I used it just as you suggested. It does tend to ball up on the threads if you use too much.

The speed bleeders do work as advertised. I recently replaced all four calipers, installed a tee, master cylinder,and new hard brake lines. I used a pressure bleeder but could not get a firm pedal after pushing three quarts of fluid through. I installed the speed bleeders (from Pelican) and got a high hard pedal, but only after driving for a few miles around town after bleeding.

The left front is closest to the master cylinder and is the last one bled in sequence. I would bleed all four: rr, lr, rf, lf.

I'd recommend the speed bleeders as we have them on all our cars, even my Ford F150! I imagine the old bleed screw was worn and there may have been some dirt in the seat area so it will weep. I would not use teflon tape. Good luck.
