Default Clutch/brake pedal assembly slop/repair question

It looks like I need to rebuild the pivot assembly for my clutch and brake pedals. How much PITA is it to pull out and rebuild the assembly?

Any insight or help is appreciated.
Thanks,
Mike

I admit up front that I'm not all that familiar with C3s, but removing the steering column will make life a whole lot easier. You may be able to do it without having to remove the instrument cluster. Once it's out, the rebuild is easy. The clutch pedal had come loose from the pivot shaft on mine and I had to get it rewelded, but that's relatively rare. You should be able to get away with new bushings.

It is a total PITA job!

Assuming you have a '69 vette:

-remove the driver's seat
-remove the driver's door sill plate
-remove the driver's kick panel
-remove the steering column and associated parts
-remove the neutral safety switch
-remove the clip holding the brake booster rod to the brake pedal
-unbolt the master cylinder from the booster
-remove the 4 nuts between the pedal box and the brake booster
-with the brake lines still connected, push the master cylinder out of the way to remove the brake booster; remove booster
-remove wiper grille
-remove wiper door
-remove wiper arm linkage from wiper motor
-remove 4 upper bolts from pedal box that are in the wiper cowl area
-remove 4 nuts holding up the steering column support lower bracket; remove bracket
-remove all screws holding driver's side instrument dash pad in place to let it drop down slightly so you can see the 2 bolts holding the steering column support to the birdcage
-loosen but don't remove 2 bolts holding cast upper steering column support in place to the bottom of the bird cage; this lets it drop down enough to...
-remove pedal box!

I can do this in a little over 2 hours; and it takes me about 4 hours to put it all back in again.

I have left most of the small details out, but this is basically how to do it

Hope this helps!

Well, that's rather depressing.

This definitely looks like a winter project where I can work on it at my leisure.

I appreciate the information. At least I can go into this knowing it's going to be a PITA rather than finding out midway through the process.

Thanks again!

7t2Vette offers great advice on what to expect. Nice write up.

The upside is you can end up with a nicely rebuilt pedal set once you replace the worn components. This was a good excuse to media blast and repaint mine:









Good luck and stay warm once the temps fall.

Fun fun fun,if your back doesn't hurt now it will. This is also one of those "while I'm in there" projects. Also be glad you have a coupe,those vert braces are a pain.
Good Luck and please turn a recorder on so we can hear the cussin.

Thanks for the "encouragement".

I've had one of the later stamped steel brackets (versus the present cast piece) gathering dust on the shelf for the past while. Maybe I'll throw that in there too while I'm at it.

I thought I remembered something you were going to do in that area,must have been the support. The instrument bulb wires have a habit of breaking off at the socket,when repairing those adding some length to the gray wire will make going back in much easier.

Sorry to be the bearer of bad news!!

It is a awkward job because of the tight confines under the dash. Have fun with the neutral safety switch and the clip holding the brake rod to the brake pedal!! The wiper door may give you grief if it has not been off in a long time, the bolts tend to seize in place.

Do you need to grease the brake bushing ?

Hi R-T,
The AIM indicates that some grease was originally used on the bushing… I think I remember the bushing is nylon (?)… so perhaps some white lithium on it?
Regards,
Alan

What NICE work by D7T2 !!!!

69427: You may want to have a look up in there. Years ago my clutch arm came off its pivot while I was out and about. If memory serves it was a cotter pin that wore out. Nice little adventure getting back home in whatever gear I could get into without a clutch and without having to stop for a red light.

I'll get my trouble light and take a peek under there. I've got a track day planned for this Friday, and I always try to minimize surprises out there.

Thanks.
