on 11/8/2008 Very well done and informative series, I have been a diy mechanic for many years, and have always replaced calipers when they are leaky or sticking, now that I have seen the simplicity of a rebuild in your videos, I will certainly rebuild rather than replace, a great way to ensure a proper rerpair and save money to boot!

thanks,

Video Transcript

"Okay, are you ready? Alright, go ahead and apply. Did you see that big burp of air come out of there? That's what we have to get rid of. I'm going to close the bleeder. Release. Apply. Release. Apply. See all those bubbles in there? That's what we're getting out. Release. Apply. You see the caliper begin to work, how it's starting to grip down on the rotor. See all those air bubbles coming out? Release. Apply. There we go. Getting good fluid now, we'll give it a couple more pumps. Go ahead and release. Apply. Release. Apply. All right, that should be more than enough. We're not getting any more air bubbles coming out and we don't see any dirty, nasty, contaminated fluids. Nice and clear. Old brake fluid will tend to look like coffee and be full of rust and contaminants. That is the proper service procedure for bleeding your brakes."
