Wifes 2000 GC Larado and my 2002 Overland......the pedal feel on the wifes WJ is so much better than my WJ. Hers is firm and the pressure starts almost right away when you touch the pedal. Mind you have to push down some before the pressure starts to apply the brakes. I have read that the 2000 models had a better brake pedal feel and that the 2002 models had a more spongy pedal feel.
Question is can I replace parts from a 2000 to a 2002 and get the better pedal feel and if so what parts make up the pedal feel? Master cylinder?
Thought it was on the 2003's, but they changed the master cylinder output pressure.
M/C part numbers are the same for a '03 and a '00 on Partsgeek, so some digging would have to be one I guess.
It was touted as an improvement to allow better braking with less effort BTW

I can think of two items that could present this difference.
One, the Teves brake caliper. It's the original caliper for your wife's '00, It's black and it can be upgraded to the Akebono caliper(silver) that came with the later '02s and on. Depending on whether the Teves caliper pistons are a different diameter than the Akebono pistons, there could be a difference in feel.
Two, the anti-lock brake module is different.
So, if your wife's Jeep has silver calipers, the difference between the brake systems is in the module. Whether that would create the difference in pedal feel, I don't know.
I seem to recall a different, softer feel when I had my early '02 model Overland upgraded to the Akebono, but that was ten years ago. It could be that the dealer did a poor job of bleeding the system. Lately, I've been entertaining the idea of replacing the brake fluid and doing an anal job of bleeding the brakes. I only hope it makes a difference.
Wifes car has the Akebono, so does mine when I switched the calipers I also did the rotors and pads and ran new fluid through both systems. So both Jeeps have the same calipers, rotors, brake pads and Dot-4 fluid...........So the 2003 master cylinder is different???
It could be the master cylinder, the brake booster (Vacuum), the antilock assy, or calipers so unless you want to go to great expense don't worry about it. As long as the pedal is "constant" meaning that you can't raise the pedal by pumping the brakes, which would indicate air in the lines & it always keeps that same level, there should be nothing to worry about. Check ALL of the brake hoses for cracks. There are a lot of hoses on the front, not just the ones on the calipers. They are double walled hoses so if the outer wall is cracked, which is common as any vehicle gets older, it could bubble out & cause the pedal to be lower. Also, check the steel hydraulic brake line that runs along the inside of the frame on the driver side. They are known for rusting out. That won't cause a low pedal but WILL eventually burst causing you to lose the back brakes. I just replaced mine, I noticed a lot of rust. It didn't burst yet but was close. If you DYI it's only about 15 bucks at the dealer for the exact replacement line.
