4. Fitting Instructions:

1. Disconnect pipe from master cylinder

3. Undo the 6 screws on the top of the clutch pedal box
4.  Remove 2x 13mm nuts securing the master push rod to the pedal assembly

Refitting is the reversal, making sure to use the new 1/2 width Nyloc nut provided, set the pedal inline with the brake pedal and bleed the system, leave the cover plate off while test driving, taking 2x 13mm spanners to adjust as necessary! You can raise the biting point by raising the position of the pedal using the two lock nuts on the master push rod. 

Tips for installing & Bleeding

1. Use a pipe clamp / soft jaw grips on the flexi hose hose to retain the majority of Brake fluid
2. Bleeding can be a little awkward, if you think there is air in the system, you can wedge the clutch pedal down over night to allow the air to rise to the top of the system.
3. On the Defender if you need to increase clearance; this can be done by adjusting the master cylinder pushrod to move the pedal assembly further away from the bulkhead increasing the stroke
