Clutch pedal position

nick · Postby **nick** » 23 Oct 2012 23:30

On my '76 car the clutch pedal is about 2 inches higher than the brake pedal. On the '79 car they are even. I have not had the '76 car on the road yet but just pretending in the garage it feels rather awkward when I operate the clutch. I see no adjustment for this as the pedal retract stop is the governed by the length of the clutch master cylinder plunger. Does anyone else see this as a problem on his car?

Have you changed the clutch liquid, maybe some air or moisture in it.

Mine does sit a tad higher, since I replaced my trio of clutch slave , master ,and hose ( still have original clutch however in my car ) ....but the pedal is definitely not "two" inches higher though!

Probably a clutch master cylinder from a different make car.
The cylinder itself is used on a lot of other cars with the only difference being the length of the actuating rod.
Clutch pedal should sit lightly lower compared to the brake pedal.

My '79 car has the original clutch master so I measured the bodies and they are the same. However the rod on the '76 is about an inch longer as measured from the pedal attach point to the pedal box. That pedal also does not depress as close the floor as the the '79 one. It looks like I may be able to mitigate some of this by drilling a new hole to attach the the pedal closer to the box.

Had the same thing appear when I last replaced my clutch master with a complete new one (now made in a different country than original). Solution was to swap the rod from the original. And if you still want the metal cap, that's another swap.

I have the same problem with my recently acquired 77 fhc. The clutch pedal is around 1 - 1.5 inches higher than the brake. It's on my list of things to look at when the car comes back from the body shop at the end of the month so will keep a check on what comes of this posting.

Unfortunately I don't have an old rod. If someone out there who is in the US has one sitting around I'd appreciate a shout. This looks like it will be a chronic problem for the wedge community since all of these cylinders are probably manufactured by the same company.

Of course the other solution is to modify the rod in the new cylinder. Removing the rod, shortening it, cutting some threads in the end and cutting some threads into the bracket would make it adjustable.

Dunno, mine come from a local brake and car hydraulics specialist in a village on the other side of the river.
He has a huge stock of original parts, and he has all the tooling to produce batches of parts when he runs out of stock.
