Air in Brake Lines
Got a question for ya:
I had (actually, have) a problem with air in my brakes (squishy brake pedal/excessive travel).
No noticeable leaks, except for the one a few of you might remember, where the brake hose meets at the caliper on the passenger side, which I believe I've fixed.
Anyways, I'm wondering if it's possible for air to be getting into the lines, but there not be leaking brake fluid. (Such as, a brake line not making a proper seal at a fitting).
It'll be February before I'm back home, so it will be plenty of time for their to be leaking brake fluid, if fluid will come out.

I suppose its possible. I would lean more towards a bad part. Master cylinder, wheel cylinder....ect that is not letting you build pressure. Or that there is air trapped in the lines somewhere. Ive had to bleed and bleed and bleed and bleed lines before they are good sometimes.

if not master check the wheel cylinders. mine went bad and took awhile before it was really noticable. Once replaced it took about a whole thing of brake fluid to get out all the air. was a pain i almost took out the abs light lol. good luck man.

Is there a way I can tell if it is the master cylinder (or wheel cylinders)? I bench-bled the master cylinder before installing it, and didn't notice any problems.
Now, here is another question: upon reinstalling my brake pedal, reinstalling my battery, I noticed that my brake lights are always on. After some investigating, the brake pedal striker was not contacting the brake light switch.
I looked up in the service manual, and, as written, adjusted the position of the brake light switch (all the way forward), which still does NOT contact the striker, so my lights are still on.
Am I correct in thinking that the rod the brake pedal actuates (that goes in the booster), might be too short?
When I get back (which just can't be soon enough!!), depending on what you guys say, I'll probably put in another master cylinder and power booster.
