Hi Cheezie, I am replacing my hydraulics too and have EXACTLY the same issue.
Situation:
- replaced the original brake dual master cylinder with a new style dual master cylinder.
- replaced my original tin style clutch master cylinder for a plastic style master cylinder.
- modified my pedal box due to pedal pivot bolt head flogged out and hole (adjacent to clutch pedal) flogged out too. So I had a bush welded over the hole and replaced the pivot bolt with a modified bolt (but no change to any of the critical dimensions).
Result: brake pedal sits high relative to the clutch pedal. WTF??? So, to give some context, I have taken a measurement of the distance between the top of the each pedal lever at rest (i.e. below the clevis pin) to the bottom of the pedal lever cavity in the firewall:
- brake pedal lever = 1.5 mm
- clutch pedal lever = 7.5 mm
Issues/Observations:
1. Brake pedal looks about the right height.
2. Clutch pedal looks like it is low, given it has to swing through a greater arc (comparatively to the brake lever arc) to release the clutch.
3. No adjustment available to either system, so one or both push rods must be incorrect length, or as Terry has indicated, there could be a shim installed in the clutch master cylinder.
4. If there is a shim installed and you remove it, will it affect the hydraulic effect; i.e. will the slave cylinder on the clutch still move the same distance?
5. The car won't pass roadworthy if the pedals are not the same height (my car is not registered at the moment).
Questions:
1. Does anyone have the original spec for pedal height? The manual gives no clue...
2. Is this issue a recent phenomenon?
Happy Mokin'
