Warning: Gas Pedal Broken

[emmvette]

During a 1 mile run at the SORC this weekend, my gas pedal broke about 140 mph and fell off to the side. I didn't realize what had happened during the run, it startled me and I hit the rev limiter. That was my first and only run of the day since my pedal was broke. Still was able to get 167.8 mph by pushing over and down at what was left of my pedal assembly. Next year will be a faster run assuming no issues. I carry spare parts but never thought about this one.

The pedal assembly has a plastic part that attaches it to the firewall / floor. After getting home today and doing a little internet research looks like this has happened to plenty of people, usually during a hard acceleration. The plastic piece is brittle and breaks. You may want to check yours for slop and replace if needed.

At least my gas pedal didn't get stuck under the brake pedal!

Here is a link to the only place I could find making a quality replacement for the plastic part:

On a side note the SORC event is extremely well put on and a ton of fun. Highly recommended!

Very strong run for 1 mile with problems

Wow, I had never heard of that before but sure sounds
like it could be dangerous.

I wonder if the part is something CT (Carter) could make
and we could do a group buy. I'd just have to get some
young whipper-snapper to go under the dash upside down
to do the replacement. Ain't as easy as it used to be!

At one time someone was making an aluminum billet piece to replace the plastic one. George.

[conesare2seconds]

I knew the guy who prototyped the billet piece. He found there were several designs of the factory pivot over the years. Eventually he was able to produce one that was compatible with all years and obtained distribution through Ecklers. Unfortunately his health took a bad turn and he passed away. He may have licensed the design but I don't think his wife did anything with it after he died and doubt it is still available. It was popular in the autocross community where a couple of racers experienced failure of the factory part during competition.

Find a wrecked C4 and remove what you need.

Are ya'll reading the original post? I found somebody who is currently making a quality replacement part and put a link in the thread. Don't buy one off a wrecked car or a "new" low quality plastic part. A wrecked C4 will still have a 20-30 year old brittle plastic piece. Buy a nice metal one. They make all three versions for the three different ones used on the various C4 years. I don't know who is making these, but you can tell its much better than a plastic one!

I remember the team braking at least 2 at a 24hr at Mosport back in 1987. They are a cheesy little plastic part . Yikes . I think I mentioned how weak they were in my Toe/Heel post's and ticked at GM for putting such a flimsy part in a C4...
I think I will get a spare also as I still T/H every time I drive but I tend to have a delicate touch with the pedals . It's not always mash the pedal each time you drive, tho it is hard to resist lol ...
Thanks for the link emm
;)

I have actually been searching the last few days for my aluminum one. I had bought it from R-D racing I believe back 10+ years ago for my 93. Cant seem to locate it but I wanted to put it into my Z. Im big on sensory inputs and my opinion is the gas pedal is and always has been a low point for C4s. Its one of the sloppiest loosest pedal Ive possibly ever felt.

thanks very much for the link.

[Gunny]

I bought some R-D Racing items awhile back including (I think) the aluminum gas pedal replacement part. I never installed it. If I can find it & someone needs/wants it let me know.

[tf95ZR1]

I would be interested, George.
Just let me know.

emvette,

Thanks for sharing and greatly appreciated. I did not mess around and ordered one from the source you recommended for my 95Z. Bill Sheffer responded right away and I'm good to go. I remember over 10 years ago replacing this part on the 90Z that I had and sold with an aluminum piece from someone else. I want piece of mind for $75 and no question here. Thanks again. Craig

Great that a new source was found. I just ordered mine from Unique Cutting and Metal Works after talking with Bill. His designs are independent from the previous source. His kits include the pivot mount, spacers to properly space the mount from the firewall (just as the plastic pivot does), pivot pin, and cotter key. He water jet cuts the two pieces, welds them together and final machines them.

I'm also tinkering with the pedal pivot and pedal face as I find it difficult to heal-toe and uncomfortable to hold at full throttle for extended periods (30 minute sessions on track) compared to my non-Corvette track car.

[Vette Guy]

While I've never heard of anyone breaking one for years, it's a part that commonly breaks on the C4s at the track - as Tripler stated, especially when you heel-toe. I carry a spare, along with wheel bearings / alternator / ECM....

TNova - keep us posted!

I heard from Joe your engine swap is almost complete on the Challenge car. Short block is done on my car, waiting for GVD top end work to be complete. Putting urethane bushings in now, DRM and VBP locators and links, lowering kit, and bump steer tie rod ends. I'll have Delta Vee rebuild/revalve the shocks. Visa no longer questions my orders from Jerry's!

Enjoy Carlisle.

ordered mine. I had the R-D one and it wouldn't fit right on my 93 which was why I never had it on. there were issues with the shims and the pin. Will try and dig it up. There was a post on facebook about a month back about these from Bill which is what had me thinking about it. Glad the topic came up thank you !

[Jagdpanzer]

Nice piece, good price, got to have one
