Firewall flex w/ brakes
I bled the brakes yesterday and had my wife doing the pump it, hold it down method. I noticed after filling up the master cylinder w/ brake fluid and had my wife pump the brakes to build up pressure, that the firewall flexes pretty good. My firewall appears to have a rubber covering across the entire thing. I couldn't tell if it was moving when she pushed in the clutch.
What's with the rubber covering? Does my firewall need the reinforcement kit from Ford?

The repair plates went on the inside, and were more for the clutch cylinder than the brake cylinder.
Just a metal stiffner you bolted to the firewall after unhooking the linkage and removing the mounting bolts.
After the linkage was remove, mounting bolts removed, slide plate in and replace everthing you took off.
Just spread the pressure over a larger area.
With a piece of 3/16" flat stock, making one is a matter of cutting it to what ever size you want and drilling the holes for linkages and mounting bolts.
Also a lot cheaper that the Ford version.
Nope, watch the clutch master cylinder.
If it move much at all, the firewall is probably cracked.
Symptoms of a cracked firewall are hard to get into gear with the engine running or clutch disengages/engages very close to the floor and it getting worse fast.
