brake bleeding

[wgabert]

I bought this truck a few months ago. the fluid is almost black, so I thought I'd change it out. I have a brake bleeder. After removing the fluid in the mast cyl and refilling w new stuff is there any problems with drawing the fluid at each wheel until clear or will the ABS cause me trouble.

 

Thanks

use a turkey baster or something to remove most of the fluid (Don t take out so much that air can get in the lines) Refill and use the EZ brake bleed with clean fluid if you have one. Get a clear tube to fit over fitttings at wheel cylinders and bleed till clear. Don t let the master cylinder empty so no air will get in the lines(refill as needed)> Start at thre furtherest wheel (right rear, then left rear, right front, left front).I usually do mine every two years.

Don't forget to insert the end of clear plastic tubing into a clear plastic bottle half full of clean brake fluid. I usually use a 1/2 liter water bottle, which I dry and flush with brake fluid before use. The line submerged in brake fluid will prevent air from being sucked into the line when the brake pedal is released. Just make sure the tubing fits snugly over the bleeder screw, and open the bleeder only about 1/2 turns. Then pump the brake pedal about 8 times (it should sink to the floor), release, close the bleeder screw and refill the master cylinder. Then go to another caliper (or wheel cylinder for rear drum brakes).

i believe he said he was using a pressure brake bleeder so i was not concerned about any air going back up the lines while pumping the pedal as there will be no need to pump pedal.
