Bleeding brakes
Alright I have spent the last 3 hours bleeding one caliper. I'm I don't something wrong? Press down the pedal, open the valve, close the valve, then release the pedal. I got the instruction from scoobymods. Air bubble just keep coming out and dont seem to be slowing down. Any tips or advice?
I changed the brake lines btw.

/\ thats your problem.....unless you have a pressure bleeder you cannot do it alone....you need someone to pump the pedal for you. By the way, just simply pumping the brakes and then opening the bleeder screw will NOT properly bleed your brakes.
You need a friend to pump up the brakes about 5 times and HOLD PRESSURE ON THE BRAKE PEDAL while YOU open up the bleeder screw.
BEFORE you open the bleeder screw make sure your friend knows to tell you when they are done pumping and "Holding" pressure on the pedal (by saying "holding" or something)....and they need to tell you the SECOND the pedal hits the floor (by saying "Floor" or something like that as soon as the pedal bottoms out, while you immediately close the bleed screw.) when you open the bleed screw (while pressure is held on the brake pedal), open it SLOWLY so as not to catch your helper off guard, and they can feel the pedal start to move.
Also, it wouldnt hurt to have the engine running while bleeding the brakes. The power assist will help push the fluid through the system and force any air out of the lines. Also, double check that you dont have any leaks and all of the connections (that you changed) are nice and tight and not leaking. A system that is not 100% airtight will constantly have air bubbles in it, and that is NOT SAFE to drive like that, not to mention your brake fluid could leak out.
Good luck

But let me add that speed bleeders are worth their weight in gold.

Thanks guys. I think I got it. I took it out for a spin and didn't get a mushy feel so I think i'm good. I induced the ABS a couple of times to make sure no air was traped. It doesn't fade like it used to seems to bite real good half way pressed with the new SS lines.
