Brake Fluid Replacement
I have a friend who has an 81 coupe and is replacing the front calipers due to leakage. While he is at it, he wants to replace the standard brake fluid with synthetic. Anyone know what the procedure is for getting all the old fluid out so only the synthetic remains? Any help would be appreciated.
Please either post a reply here, send an e-mail or IM. Thanks a million.

Re: Brake Fluid Replacement (JDs00PewterCoupe)
Here's what I did when I mixed the two by accident :cuss :smash:
1. Remove all 4 calipers and thoroughly drain them, rinse with isopropyl, then fill with new fluid.
2. Disconnect all brake lines, drain, rinse with isopropyl, then fill with new fluid. Go down to the hardware store and buy a big animal syringe (for giving worm shots to horses) and a short length of tygon tubing. Fill the syringe and hook it up to the disconnected lines with the tubing. This really makes the work go faster. You can also use this method to fill the lines with new fluid as you gradually put them back together.
3. Remove the master cylinder, clean, alcohol rinse, fill with new fluid and bench bleed prior to installation.
I don't think it's a really big deal, but it's time consuming. Now is also a good time to replace the short rubber lines as well.
Oh yea, 4. Bleed the brakes :lol:
