Hello - I have an 88 f-150 302, with a 5speed tranny - when I push the clutch pedal in, it doesn't want to come back up. Plus, the brake pedal travels down with it as well... First off - this truck has been sitting for 6 years, so I know my brakes need overhauled. I don't think anything is wrong with the slave cylinder, as I can tuck my foot under the pedal and bring it back up - It seems to go in gear fine (when I say seems, I mean, I can't say for sure because my rear wheels are locking up, different issue)...

So - could this simply be the center spring I read about on the internet? And why would my brake pedal go down with the clutch pedal??? Help please...Thanks

 

1)The pivot and /or linkage plastic bushings could be shot.
2)You might check for firewall flex/tearing.

If both pedals move when you step on one there's a danger that the Zamak pedal pivot/ steering wheel support is cracked and ready to fail.

THAT's exciting!........ when you're driving and the steering column falls in your lap.....

 

Have to agree. Only thing worse is the wheel coming off in your hands when driving. My '67 International did that once. Didn't know that the seller removed the nut and put the horn button back on. Good thing I was wearing black jeans at the time.

Seriously, crawl under the dash and watch what happens when the pedals are pressed. It sounds like the bushings are shot.

 

If the bushings are shot, is that something that I could replace easily?

 

Shouldn't be too hard. You have a shaft under the dash that the pedals ride on. The bushings on each side will go bad. I am going by Dodge spec's since my Ford is an auto but they should be close. Take a look under the dash when the pedals are pressed and you should see where the slop is.

 

I will. thanks for spelling out what to look for. I'll post what I find...

 

This might help some.

 

OK,
In addition to the isometric illustration in the lower view you see on the right side what's referred to as the 'lever'.
There is a 4 pronged plastic clip that connects this to the 'eye' of the master cylinder pushrod.
This clip is often worn or broken.
In my case it caused enough freeplay that the clutch would fail to release completely.
After replacing it many times I ended up putting a brass bushing there and retaining it with a washer and 'hairpin' clip as can be seen here;

Just another thing to look for......
