Reply to "Final Brake Bleeding and adjustments"

After sitting for 30 years I expect a few solidly plugged areas. I have had to DRILL out some bleeders and ports to remove solidified varnish. Check visually and with wire probes for clear areas. I've also had to do this to the cam bearing oil feeds on older engines, especially those with oil feed restrictors.This in spite of boiling blocks out in very hot solvent washers. Age hardened varnish is very tough stuff!

With the movable shuttle valve and the movable non-adjustable stock proportioning valve, I doubt if a rock-hard brake pedal is possible even if perfectly bled. Thats one reason why I deleted both in my Pantera back in the last century. Others gut those parts for a more stable platform with the stock look. You will almost always feel moving parts inside any hydraulic system. Manual adjust proportioning valves have no spring-controlled movable parts, and all the shuttle valve does is turn on a red dash light if one caliper somehow develops a leak.. Which a perceptive driver will see in low fluid level during "preflight" look-overs anyway.
