brake pedal differences?

When converting from manual brakes to a factory power brake system, is the same brake pedal used? I know when doing a similar swap on other vehicles, there is usually a different brake pedal because of the difference in force required to apply the brakes butI've never seen that mentioned in any jeep posts I've read.

There is a different brake pedal used for power brakes vs manual brakes but I do not know what the difference is.
I converted to power brakes back in 1988 and only purchased new MC, MC brake lines, Booster, Booster brackets and a brand new factory Air Cleaner w/offset. Never knew about the different pedals back then and never had a problem with the original manual pedals I still use today.

The only difference I've met has been pushrod length Fiber.

It depends on the year of your CJ, because some use the same part number whether power or manual.

I briefly looked it up in the parts manual and it looks like there are indeed two different ones, I would have to check the year to be sure though. thanks for the tip

Would fitting a remote servo make life simpler?

HI Not sure but I think the pedal are only different if its a Automatic.. They usually make the automatic pedal longer so it is easier to access with the left foot..
good luck

I think Keith460 answered it, there is a difference but it doesn't seem a major one. I currently have manual brakes, I also have an OEM booster, booster bracket and a master cylinder (which needs to be replaced). My concern was that the manual brake pedal would not fit, in Keith460's case it seems to be OK after all these years.

When I converted my 1980 Cj5 with manual transmission from manual to power brakes my process was only to change out the manual MC assembly with a with a factory CJ booster and master cylinder assembly with bracket.. After I was done I had 2 issues. 1st the pedal height was not equal with the clutch pedal height. I resolved that by changing out the push rod with an adjustable version that allowed me to set the pedal height equal . The 2nd issue I had was that my motor did not have enough vacuum to properly operate the booster. The stock CJ booster requires 22HG to properly activate. Since my motor only put out 17HG I installed an inline vacuum booster that kicked me up to the required 22HG.. I have been running this setup for years with absolute zero issues. The only items I had to change was the booster assembly with bracket and the push rod. I'm not sure if an automatic Cj7 requires something different or or if the manual CJ assembly verse the auto CJ assembly would require the same approach.

Hmm, don't seem to have that problem. If there is a difference in pedal height, its very subtle.

Is the pedal for one with an A/T wider than a normal Jeep?

Yes. It's roughly twice the size of the standard shift brake petal.
