An odd situation...
Well, at least for me. Here's the story: I have been working on my clutch for some time. I'm stuck at the bleeding point. Well, I repaced the pedal return spring. Well, mypedal still stays where it did before the clutch went out. Well, I noticed that the firewall where myclutch master cylinder is flexes and moves. Would that causethe pedal to not return all the way? And if that is what causing it, what adhesive should I use to fasten the firewall to the vehicle. Oh, Its a 1988 F-150 with the Mazda 5-speed if that helps much.

what to fix it with im not sure other than possibly puttin sheet metal over the area and surrounding area to strengthen it again, all i know is that its something you want to correct a.s.a.p. my brother in law had a late 80's ranger that had the same issue, he kept screwing around and never fixed it, well long story short one day i had to borrow his truck to run to the parts store, went to hit the pedal at a stop light and the firewall gave way and ripped apart... limped to the parts store where i "fixed" it with a ratchet strap around the master cylinder down to the frame lol, got me home tho

These are a bugger to bleed. Are you following the correct procedure? If not, you have to fill the master, open the bleeder and let it drain a little, Refill the master, then let it drain, making sure not to let the master go dry. Repeat this 3-4 times, then pump the master, hold it, and open the bleeder, close bleeder, pump master, hold, open bleeder.
firewall flex is a common problem, how much flex is there? All flex a little, but if its really flexing or if the firewall is cracking around the master then you may need to reinforce.
Another common issue is the bushing on the clutch pedal. It wears through to the point that the pedal doesn't hardly push the master. You can get stock replacement bushing from ford but they tend to fail pretty quick. Its really easy to do a permanent fix instead.

Another is for more serious damage. This kit costs about $100-$150 and is supposed to take a few hours to install. But, if your firewall has flexed to the point of cracking/tearing, then this is the way to go.

From what I can see there is no tearing or cracking, it looks like the adhesive is starting to wear out. because some of the adhesive is missing. So. this $10 part, is that ford specific or does the auto parts store sell them. Knowing my luck Ford specific so they can charge me out the rear end.
