Is the pedal loose and floppy or is it firmly stuck to the floor ?
Who fitted the clutch for you ?
I assume there was some fluid in the reservoir, if so what condition was it in, was it clean or dirty black.
Yf the pedal is stuck hard to the floor then I would think that indicates there is something wrong with the clutch itself, perhaps in the way it ws fitted. If the clutch pedal was making nasty grinding/squecking noises after you had the new clutch fitted then I would say that the whole pedal assembly has broken off the bulkhead (this can happen), and the only way to mend that would be to get it welded back into place.
The brackets I make are designed to support a clutch pedal assembly that still operates and is working, it's designed to releave any side to side movment in the pedal and thus stop the whole assembly braking away from the bulkhead. If your whole pedal assembly has already broken away from the bulkhead the bracket alone will not help you.
