brakes bleeding
I have to replace the master cylinder in my 88, but I'm kind of confused as to the proper bleeding procedure, I have three different manuals, factory(does not describe a procedure)Haynes(talks only of bleeding the calipers)and a chilton wich says that you have to bleed first at the hydraulic modulator.which way is it any one?

Mine is a 87, but my shop manual specifises right front, right rear, left rear, left front.
If you just need to bleed the master cylinder, mine came with plastic fittings which screwed into the master cylinder where your brake lines normally go, Attach 1/4" tubing from the fittings and place the loose ends into the top of the reservoir so that they are submerged in the brake fluid there. Work the brake pedal to force brake fluid through the internals of the master cylinder. Then, quickly attach each brake line fitting after removing the temporary plastic fittings, one at a time.

You should most definitely bench bleed the m/c as Strike3 described, then after it is in place bleed the entire brake system thoroughly to flush out as much of the old fluid as possible and of course to bleed.
It is not all that important which wheel you do first if you are flushing thoroughly. Go around the car to ensure that all wheels are bled free of air, then go back around one more time so that you are completely flushing to introduce fresh fluid throughout the entire system.
Annual brake flushing will virtually eliminate the need to ever replace or rebuild m/c or calipers.
Good luck and Merry Christmas,
