I have read that the brake pedal is supposed to be higher than the clutch pedal, but have not seen anything about the height of the accelerator pedal.  Mine is 3” lower than the brake pedal and I keep catching my size 10’s as I go from gas to brake.  The accelerator pedal height is fine for me so would like to drop the clutch and brake pedals down an inch or two if at all possible.  My car is a 95 SPi and I’m getting full travel on the accelerator pedal.  Any thoughts?

Brake and clutch pedal are kind of fixed at the height they are by the design of the pedal box - No easy way to bend/adjust the brake and clutch pedals down and even if there was  you would reduce the travel of those - not ideal for the brakes and might mean the clutch wouldn't work - you're going to have to live with them unfortunately - its like the steering wheel angle just a mini thing

 

However a bit of brute force and bend the accelerator pedal up to the height nearer the brake pedal you would like it to be (preferably take it off the car to bend it but....... )

 

Personally want it to be about 20mm lower than the brake pedal for heel and toe-ing but each to their own

 

(Size 9 so not much smaller than a 10)

It might be possible to bend the brake pedal sideways a small amount, but then care needs to be taken not to jam the foot against the column.

 

The high brake pedal seems to be designed so that way so in the event of one of the dual circuits failing the pedal has sufficient travel to the floor to ensure the good circuit can be fully pressurised.

You can adjust the stop of the brake pedal using the threaded rod on the brake servo. It's a pain as you need to remove a fair bit to do it. To make it go down, wind the end of the rod inwards towards the servo.

Remember to adjust the brake switch after!

Thanks for the responses.  I think I'll investigate adjusting the threaded rod on the brake servo first.

You're missing  the heater intake hose too - as an aside.

I don't know where the problem is with the accelerator pedal. If I want the pedal as high as possible, fully tensioning the cable that enters the system that opens the carburetor butterfly. And if I want the pedal a little lower, then I tighten that cable leaving a little slack and without it being so tense.
Half a centimeter of cable less tense in the carburetor = half a centimeter lower on the pedal.
Because the pedal, inside the car (at least mine) falls or descends due to its own weight. Therefore, if you leave it looser where it attaches next to the carburetor, the lower it will be inside the car.

I removed it as my size 10's were also catching on the hose when using the clutch

You can see in the pic the pedal is against the stop.

I would have thought the primary concern would be to match the fully 'down' position with the fullest extent of the carb/throttle body flap, making sure that there isn't enough pedal travel to stretch the cable or damage the levers at the other end

 

once the pedal is in that position, however far it comes back up again (assuming it allows the throttle to close all the way) is all you get, not much you can do about it

 

lifting it up more to line up with the brake pedal just means you're back to stretching the cable again, unless you have a stopper behind the bottom part of the pedal to limit travel

Steve, if he starts by removing that carpet to see what margin there is until he hits the floor without anything hindering him? I think that this way everything would be clearer.
