Clutch fork could be on its way out?? The original forks were quite thin and would wear through on the little ball pivot to the point the pivot would punch through causing the clutch pedal to stick down. Yours could just be on its way through??
If it is this then you can now get heavy duty forks which have reinforced pivot points. |

Where is the bite point of the clutch and how high is the pedal compared to the brake pedal? You might be able to adjust the pedal stroke if the bite point is high, or adjust the big bolt on the clutch pedal box to stop it going right to the carpet.

First bleed, then try adjusting pedal, but if that doesn’t work take your pick of changing salve or master cylinder. Mine was master cylinder

Probably the master, clutch spring getting weaker or slave in that order of priority.
Typically stays down due to a lack of pressure, check for any leaks around slave but MC is probably the most likely culprit. $W33T $0U7H3RN $UG4R 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

It is most likely the pedal pivot shaft is rusty and the pedal is seizing on the shaft.
Need some oil on the shaft. You can probably get to the ends, might need to remove the cover to get to it better. Oil it, then move it up and down for ten minutes to get the oil in and wear the rust off. |

The end of the pivot shaft has a tapped hole in it. I’ve fitted a grease nipple to mine that makes a big difference in required pressure and noise.

Unfortunately not all shafts have the tapped hole, but if yours does the nipple idea is well worth doing.

Thanks guys - being totally non technical I’m passing the job on to the village garage who are LR indies and fanatics (but mainly of Disco 1 and 2) so I’ll print the page and pass it on. Pangea Green D250 90 HSE with Air Suspension, Off-road Pack, Towing Pack, Black Contrast roof , rear recovery eyes, Front bash plate, Classic flaps all round, extended wheel arch kit and a few bits from PowerfulUK Expel Clear Gloss PPF to come
2020 D240 1st Edition in Pangea Green with Acorn interior. Now gone - old faithful, no mechanical issues whatsoever ever but the leaks and rattles all over the place won’t be missed! |
