Hi guys, I just completed the LS1 MC and booster swap and started my car for the first time since the beginning of winter last year. Its been so long since I last drove my car that I cant remember how much travel the brake pedal normally has. After this swap, it could be just me, but it seems that I only have about 1.5" or 2" of brake travel. Can anyone tell me if this is normal?

 

Possibly, the LS1 MC has a larger bore, which in general reduces the pedal travel. However, the stock MC is a quick take-up design, which will also reduce pedal travel.

But, if the front brakes have been upgraded to a non-low drag design, then the quick take-up isn't required. And won't have much affect on the pedal travel.

I can tell that when I reach the end of the stroke, its not due to the pads pressing on the rotors, its hitting the end of the MC or booster stroke. I just need a reference to what the max stroke at the pedal is supposed to be.

 

Ahh, wasn't thinking along those lines. I did find this in the '92 FSM:

-=-=-=-=

Brake pedal travel (disc/drum) (nominal): 2.25 inches

Brake pedal travel maximum with 100 lbs force applied to the pedal with ignition off and vacuum assist depleted.

-=-=-=-=

A little confusing to me as they state it as 'nominal' and then as 'maximum.' This would also be with the system bled and sealed up.
