Cleaned off al the brake lines and fittings. I've blead the brakes. And I'm still losing preasure, faster on the passenger side. But I cant seem to find any fluid coming out. Wondering if I'm only sucking in air. Any ideas on how to locate it?

Check your cutting brakes, the seal may be leaking. The rubber boot around the piston will hold a lot of fluid before it starts dripping.

pulled the boot back, doesn't seem to be there. The res does not get lower. I think i'm just adding air instead of losing fluid.

Anywhere you have a seal could be a culprit, even connections between lines. Your master cylinder, cutting brakes, calipers, and any line connections could suck air in if they are leaking.

A vacuum brake bleeder is your best friend when it comes to bleeding the brakes out. If you pull a vacuum on the line you may be able to hear it hissing where it is leaking. There are little hand pump ones that can be had for cheap, they don't pull a lot of vacuum but should do the job.

If you use a pressure bleeder or even a bug sprayer type you will find those pesky little leaks!

that may be it. But I think I have a slight wable at my bearings. This would cause the calipers to back off and take extra travel to tighten back up. Going to work on it tomorrow and see what that does.

I had that problem before too, change it out and it will be fine. Who would a thought?

Just seemed funny that the only time it needed bleading was if i drove it 100 ft.
