I haven't tried the header wrap yet. I rechecked the linkage to the MC, and all seems ok. When the pedal is pushed there is about an inch of travel between the firewall and the brake pedal arm (firewall side) before the MC rod has started to become engaged. The pedal return spring seems strong, and the pedal will slap back against the firewall when the pedal is released with no indication of binding.
With the drum removed, the WC on the LEFT REAR seems to work properly when the brake pedal pushed, but not pushed so as to cause the ends of the WC to be expanded too far.
other stuff:
- Huck brakes
- after returning from a test run, the front wheels will also be tight, but not to the extent of the LR wheel
- after the brake system has cooled down and the LR wheel can be turned again, its wheel cylinder is still expanded somewhat and it will spit fluid when the bleeder screw is opened
- never have to pump the brakes to get pressure
- the RR wheel will stop ok when the brake is applied
-the parking brake cables have been removed, as has the arm that attaches to one of the brake shoes in both rear wheels
If the header wrap doesn't solve the problem, I might install a MC rebuild kit on the assumption that I have a bad valve in the MC.
