New Brake Pedal Troubles...

[307 Regal]

I recently bought a set of brake and clutch pedals and decided to test fit them. I just about had it all set up when I realized the post on the brake pedal was too large in diameter to hook up to my brakes.

What types of tools could I use to get this post to the correct diameter?

the post is ok, you can get a rod with a 5/8 eyelet

I don't have to take the master cylinder off to change the rod, do I?

I just read this on MonteCarloSS.com:
"Note that the pin for the master cylinder pushrod is a different diameter for power brakes than it is for manual brakes. The pin is also in a different hole. The pin for manual brakes is larger and uses the upper hole. The pin for power brakes is smaller and uses the lower hole."
I seem to have the pin for manual brakes in the lower hole.

you can buy adjustable rods with the larger eyelet

my manual trans brake pedal had a larger post as well. i simply got under the dash with a mini air grinder and a reamer/ deburring bit. opened up within seconds and moves fine

That was my first thought but I don't think my pushrod eyelet will have near enough material left to be strong. I'm probably going to see if I can get the pushrod changed. If that for some reason doesn't work, I'm going to modify the pedal itself on the automatic brake pedal. The pedal arms look to be exactly the same between the auto and manual brake pedals. I should be able to trim down the auto pedal and slip the manual pedal pad over it.

Well, I've always admired manual shift cars as a kid. I like the thought of having more control over what your car does. You get to decide when it shifts to what gear. (I'm constantly up and down shifting my shift kit automatic since I like the thought of it so much.) Then there's the clutch. There are lots of new things you can do with that. Like push start the car or build rpms to various places instead of installing a torque converter. Or even just rev the engine without having to find neutral in an automatic shift pattern. :lol:
But past any advantages or gimmicks, there's the cool factor. Is it the best reason to do this? Probably not, but I'm more than willing to do it. I've driven a handful of manual cars and it's a totally new driving experience. In short, it's more fun and entertaining.
I'd like to go with either a 5 or 6 speed transmission. I haven't done any research yet but I know I still want an overdrive gear.

The eye on the pushrod is to just hold the pushrod onto the brake pedal. When you press on the brake pedal, the force, or pressure, from the pedal "post" is pushing agaist the side of the eyelet where the pushrod intersects with the eyelet. The force is should be very linear, if the pushrod is aligned correctly. I hoped what I wrote made sense.
