I just replaced the disc brake seals and boots.I had to disconnect the front brake lines at the frame. Now I need to bleed the brakes. I am not sure what to do next. The manuals all say "compress the brake metering button" I have no clue to where this is. Not sure if this is the original master set-up. Can I simply have another person depress the brake pedal to the floor, then I will loosen the bleeder, tighten then repeat until I get clean fluid to ooze. Any easy to follow advice? Thanks.

Don't worry about the manual. It's easy to bleed any brakes. You just need some new brake fluid, never reuse the old stuff no matter how clean it looks, a plastic bottle (like a soda bottle), some tubing and a friend that owes you a favor. Bear in mind that this is my favorite method. Drill a hole in the soda bottle cap just slightly smaller than the tube. By the way the tube has to fit the bleeder nipples. Push the tube through the cap so it goes to the bottom of the bottle. Put a box wrench on the bleeder nipple then push on the tubing. Leave the cap on the bottle slightly loose so it does not build up pressure. Have the friend that owes you the favor put pressure on the brake pedal then open the bleeder. Don't let up on the pedal until you close the bleeder screw or you risk having air sucked back in. Close the bleeder and let up on the pedal. Repeat this until you see no more air bubbles in the bottle. Be sure not to let the master cylinder run dry or you will have to start all over again. When I get down to just a few bubbles coming out I have whoever is helping me (my wife) pump the pedal 3 times then hold pressure, then I open the bleeder as before. The pressure in the line will make all the smaller bubbles merge together into a few large ones so you have a better chance of getting all the air out. If you simply pump the pedal with the bleeder open it can take forever to get it right. I like to start at the wheel farthest from the master and work my way closer till I have them all done. Piece of cake!

Thanks for the technique. Worked perfect! I rebuilt the calipers myself with a caliper rebuild kit. I initially put the piston seals in backwards...brake fluid everywhere! Good lesson learned here! lol. Replaced the inlet hard lines hoses, new pads, got my buddy to pump the brakes, hooked up the bleeder tube, bleed the brakes and presto! A first gen brake expert is made! Thanks again! Dan
