C1 factory clutch pedal height

[Stewart A.]

Not many people know this but there are 2 settings for the height of the clutch pedal inside the car. For the people who know there stuff on C1's can you tell me which one is the correct clutch pedal height. I have set mine in the position that is at the same height as the brake pedal. But just wanted to know which setting was used at the factory. Thanks Stewy

Stew,
The 2 holes for setting the clutch are for normal or quick release, not actually for height settings. The difference is that in the quick release mode you push the clutch a shorter distance for release and then engagement. I think the distance is 4 1/2 inches for quick and 6 inches for normal. I'll have to look at my 62 to find out which setting is "normal".

The car is delivered in the high setting.

Re: C1 factory clutch pedal height

I'm 6 foot and always found the clutch in the high position was very uncomfortable. So I changed it to the position where it's the same height as the brake pedal. If the clutch was set in the high position why wouldn't they have installed the brake pedal at the same height ? It kind of doesn't make sense that the pedals are set at all different heights. Bruce you are correct I can feel and see that the pedal in the shorter position does have a different throw and is a lot shorter. I Just never knew which factory height position the pedal was set at.

Re: C1 factory clutch pedal height

The clutch pedal height is set by the thickness of the rubber bumper where the pedal rests against the pedal support in the "up" position, and is the same regardless of which "throw" setting is used for the bracket where the pushrod attaches to the side of the pedal arm. When you change the "throw" geometry, you need to re-adjust the clutch linkage to achieve correct pedal free play.

Re: C1 factory clutch pedal height

What rubber bumper it's all metal to metal here John ? What is the correct height the clutch pedal should be. I have asked a few people over the last couple of years and they have all told me their clutch pedal is the same height as their brake pedal ? Should both pedals be the same height. Stewy

Stewart,

Do you have the ST-12? The adjustment is shown on page 6R-3 Clutch. There is a Clutch Pedal Free Travel Adjustment and a Clutch Pedal Total Travel Adjustment.

John:

The bracket (not the pedal) sits against the bumper. The adjustment does lower the pedal.

Mine come down at least 2 inches !! Now it's at a much better height. Stewy

Bill -

Yup, you're right - I must have been thinking brake pedal.

Maybe John, but the illustration in Corvette News (when the feature was introduced for the '59) shows exactly what you described. It shows the pedal in the same position, and the travel changing. I had to do the adjustment on my '59 to figure out what was gonna happen! The pedal got lower, the effort higher, and the feel more direct.

I'll be putting it back to as-delivered in anticipatiion of the traffic on Woodward during the Dream Cruise...

Re: C1 factory clutch pedal height

Bill or John, what do I need to adjust to change the height of the clutch pedal. Besides shifting the pedal bolt hole which I have already experimented with. Stewy

Re: C1 factory clutch pedal height

Stewart,

The procedure is described in the 1953 - 1962 Corvette Service Guide (ST-12). A copy is available in the NCRS store. If you send me your email address I will send you a PDFversion of the pages about adjusting the clutch pedal. This way you can keep going until you can get a copy.

You flip the pedal rod "upside down". The rod should "hold water" with the pedal in the high position. (The ST-12 does not tell you which rod position to use with a given pedal position. Maybe it's obvious, but my car is apart so I can't tell!)
