The clutch pedal was very stiff and wouldn’t move under gravity and brake pedal was going the same way. A week ago, I attempted to remove the whole pedal mounting assembly, only to find that a bracket on the steering column was in the way. I managed to remove the pedals, the clutch one being more difficult which also left the copper sleeve on the pivot spindle.
With my little helper (soon to be 10 son), we unbolted the steering column support mounts and undid the four bolts mounting the steering shaft to the steering box. Though a load of oil came out of the steering box, it enabled the column to be turned thus moving the column mounting bracket out of the way. The pedal mount bracket was then extracted after the brake master cylinder bolts and one other bolt were removed from the bulk head.
With the bracket removed, the clutch pedal was eased back on and with some luck or patience, the copper collar came off too with lots of twisting, wiggling and gentle prising off.
The spindle that the copper collars and pedals mounted onto were fairly corroded and dirty, so out with the variable speed drill, a flexible cord with a chuck on the end and small grinding bits (bit like a Dremel but bigger). A vice to hold the bracket and they came up nice and clean with the pedals now freely moving on their spindles.
The little movie (mp4) will hopefully demonstrate how and what was used to clean the spindles.
