Brake Pedal Adjustment

Does any one know how to bring the brake pedal closer to the floor boards?

My pedal seems to be to far out, when breaking, you can not heel-toe as the is about one inch between the break pedal (when depressed) and the throttle. It is a real big roll and the brake pedal begins to slip from under my foot.

I found the shaft from the master cylinder that has two nuts on it, but moving them only seemed to introduce additional slack in the pedal that must be taken up before the brake pads engage.

The other issue is that you really need to lift your foot off the throttle and bring your knee back to move to the brake pedal, it is kind of dangerous.

The clutch pedal and the brake pedal are about even.

Or could I be looking at this backwards, is my throttle pedal to far down, and needs to be adjusted out?

I hate linkages!!!!!!

Instead of moving the brake engagement point closer to the floor, why not raise the accelerator pedal closer to the brake pedal? You can adjust the height of the accel. pedal using the nylon adjuster (no. 72 in parts illus.).



Reason why you should raise the accel. pedal is that you don't want to run out of brake travel .... ever. The more travel the better in case the brake fluid boils and air in the system. This results in less brake for the given pedal travel.

If you adjust this, confirm the throttle travel; closed to WOT. Some owners install a simple spacer on top of the pedal to raise the contact surface closer to the brake pedal. The spacer can be made from any available material (rubber, aluminum, wood, etc.). Some guys attach another gas pedal on top of the existing one.

In addition, the typical heel and toe technique may not work on a 911. Try using the inner half of your foot on the brake pedal, then roll the foot to the right to blip or depress the accelerator.

Hi Jon,

Just the other day, I adjusted my brake peddle (down/back) using the primary linkage to the MC. With the large brake linkage bar between the brake peddle (cluster) up to the MC; I simply loosened the nuts and twisted the bar until I attained my desired peddle position; then secured the nuts again. I even safety wired the nuts in place. This is very similar to adjusting the foot levers on a motorcycle.

Other than repositioning my peddle, I didn't find it to introduce any more or less "slack" as you say; just re-positioning for me...

Interesting! Good luck bro!

Tom

Thanks guys,

I am going to have to look at how a couple of other cars are set up to see if it a problem with my car, or me not used to the set up.

Tom,
the 73 does not have a boosted brake system and the m/c is bolted up just outside of the pedal cluster area. I think your year is the first year for boosted and the push rod from the pedal to the m/c is a great way to get the pedal exactly where you want it.
Jon, you may want to look at an aftermarket gas pedal that has been designed to assist heel-toe plus using the throttle adjuster nut to get the right feel for you.

Thanks Tony!

Ya'see, this is EXACTLY the reason why I tell my wife I need multiple pCars to cover all the various technical generations... lol

Mahalo,
