Not having a good day! 
My car (Corolla Twincam) failed its MOT on poor handbrake on one wheel, so today I've been changing the caliper for a recon one. I bought one of those easybleed kits in advance.
Old caliper came off fine, new one went on fine, so I started to try to bleed the brakes. I then found the kit didn't fit my master cylinder, so I had to go to halfords and buy one of the one man bleeding kits. I went to use that, then found that the new caliper has a 7mm bleed nipple, rather than the 8mm of all the others. As I didnt have a 7mm spanner, this required another trip to Halfords!
I have since been trying to bleed the brakes having no success at all. I started with the passenger side rear, followed the instructions etc then when I thought it was done (no bubbles), did the nipple back up. I then did the driver's side front and followed the same process. However, I'm finding when I open the bleed nipple I get fluid seeping out as well as entering the tube - is that normal, as to me if fluid's getting out, air can get in?
I've probably gone through about 300ml of brake fluid now and when everything;s done up, the pedal just goes to the floor, but I can't see any fluid leaks. Unfortunately, I've disturbed both ends, as after re-connecting the union to the rear caliper, I found a copper washer on the floor. I didn't know where this was meant to sit, so undid the front brake line to check.
Is it just a case of keeping going for ages, or am I missing something daft? (never bled brakes before)
Just to let you know the process I'm using, I attach the tube, undo bleed nipple, pump the brake pedal about 10 times, check to see if there's air in the pipe, (also keep checking to make sure the master cylinder's full), when there isn't I tighten the nipple and remove the tube.
When doing the front brake, I keep getting large pockets of air trapped in the tube and can't work out if it's because the tube's at a daft angle or if it's coming out of the bleed nipple as no matter how much I pump the pedal it always seems to be there. I had to open the nipple a fair way on this to get fluid to come out, and then it's weeping around the nipple as well as into the tube.
Any tips/ideas?
