idle for 6 years, replacing all wheel cylinders whats the best procedure.drain all brake fluid through old cylinders 1 at a time, then replace brake fluid then replace wheel cylinders, or replace wheel cylinders then replace fluid.

well if you pump out all the brake fluid then you will have to bench bleed the master cylinder ,, best if you just change wheel cyls. one at a time and then if you feel the brake fluid is dirty and want to replace it just bleed brakes till fluid runs clear.

The way I would do it remove all the wheel cylinders let the old fluid drain and pump new clean fluid into the system then install the new cylinders.Then do the final bleed through the cyls.There are so many different ways of doing this job but the object is to have a completely clean system after,if you don't drain the system before installing new cly you are only putting the old fluid in the new clys...FRED

The one item I didn;t change right away ( idle for 10 yrs) was the master cylinder. Wrong answer. Manny Gomez told me to. It finally STB after new cylinders and a few hard stops. Total cost for new ( non power )was a whopping $27. Stupid on my part. I would consider replacing or rebuilding the master. My new one doesn;t have the bleeder things so it's not quite "correct" but for $27 I wasn;t going to mess with rebuilding.

Also, if you choose to stick with drums, you should consider shoes from Praise DynoBrake in Texas. They're expensive, no doubt ( like $175 a set), HOWEVER, IMO they bring my 67 down from 115 mph BETTER than a disk/drum combo would. With new hardware ( springs etc) the whole set ran me $250. I know it's big money for shoes but they work superb. Disks may be better for "normal" stopping say from 55 or so, but for stopping after a 1/4 run, the Praise shoes are awesome. NO FADE. FWIW.

Lastly, my 67 is a resto not driven daily and put up for 4-5 months out of the year. Sicne I was going to drain all the fluid and flush anyway, I used DOT 5 fluid. Better for storage, doesn't absorb water. Some say it doesn't stop as well, and all I can say is that my brake system has no "pucker factor" at the end of a 1/4 run and it's a pretty fast street car. Again FWIW.
