I have read several threads saying there is a very hard pedal effort after either of these upgrades.............compared to stock ?

Still worth it in your opinion ?

Please give as much detail as you can.

Thanks.................

 

I don't own either. But based on the hydraulic characteristics, the 1LE will have a higher pedal effort than stock. LS1 will have lower pedal effort than stock. They really are on different ends of the spectrum.

Anybody who says pedal effort on the LS1 is higher than stock has one of the following going on:

1. some kind of problem with their LS1 calipers (blockage, piston sticking, slider pins bent/corrosion)
2. some kind of installation issue (air in lines)
3. larger than stock master cylinder bore
4. pads with lower friction than on their stock setup
5. have modified their pedal leverage
6. have removed booster or damaged booster

The only other possibility is that people are confusing a faster pressure ramp rate as more effort. It is easy to see how this can happen. Pedal resistance for both kits gains faster with pedal travel than stock.

Yes that chart is priceless and I believe I have thanked you for it before.

Those of you with LS1 FRONT BRAKE UPGRADES CARE TO CHIME IN HERE ?

Pedal effort reduced going to LS1 from STOCK ?

 

Define more effort than stock.... I say this because I had pbr brakes in back and stockers in front and at the race track trying to push the brake pedal through the radiator past the front bumper I would just barely make it slowed down enough for the turn off for the return lane now I just ease on the brakes and slowdown in no time at all BAER Track 1Le set-up in front now

 

OK I like what I hear. Is the Baer 1LE setup much different than the normal 1LE setup ? Same ?

 

My pedal effort was reduced and the stopping power improved tremendously, night and day difference. It was one of the best upgrades I did to the car.

 

Ls1 front stock iron disk back With stock disk drum master. Big difference I also have a umi torque arm. Its luke nitrous for stock brakes. I will install a ls1 master and I plan on going 14" ss brembo witch is over kill but looks nice

 

LS1 or 1LE ?

 

I did the LS1 disc upgrade and the pedal feels the same to me but the car stops MUCH better. It does tend to kick the front wheels out 4-5 mm though.

With the stock brakes (NON 1LE) I felt like I had to push the brake pedal thru the floor and I still wondered if it would stop. lol. Not any more

 

I have the LS1 fronts and stock iron disc in the back, with a disc prop and a disc/drum master. The brake pedal is about the same in effort and distance, but stopping distance is much lower. At the moment the fronts seem like they are too much 'brake' for the car, but I think that is because the rear is weak.

 

I have never seen in person the 1LE brakes, but I have ran the LS1 brakes and am familiar with them. I would think that they both would be about the same effort because they are both a two pistons aluminum caliper on a 12" rotor. Why not?

 

The 98+ FB front caliper is very similar to the C5 caliper in appearance and function, but there are a few differences. C5 calipers are very similar to the standard 98+ FB calipers, except the C5's are manufactured by PBR in Australia.
The C5 caliper has full width stiffening ribs whereas the 98+ FB caliper does not.
The only dimensionally difference between a 98+ FB caliper and a C5 caliper is the gap between the ears and the caliper body ... the gap where the rotor spins.
The C5 caliper has slightly smaller pistons (40mm vs 44mm). Pistons in an 98+ FB are larger, but made of thinner material vs the C5.
The C5 calipers are pressure cast (not forged, but better than cast) and seem to eliminate "spreading" (under extreme use, the cast 98+ FB calipers have in some cases started to open up or bend outward). The 98+ FB calipers are regular cast aluminum.

The C5/ZO6 caliper will fit with the stock 98+ FB bracket if using the stock sized rotor. Another diff is the mounting tabs on the caliper, the C5/Z06 ones are thinner.

C5 brakes have about 10% more pad area than the 98+ FB brakes. That will give you a large sweep area which translates to better braking.
The swept area of a 98+ FB brake is 65.7 SQ CM. The swept area of a C5/Z06 brake is 72.0 SQ CM.

I upgraded my 96 Firebird (single piston 10.5" rotors) to the LS1 calipers and rotors, and then to a C5 caliper. Car never stopped better.

my setup

 

They have very different piston areas. See chart attached above.

 

i have ls1 up front and 1le in the rear. other brake components are stock. (no mods to master or booster, etc) Brake pedal feel is same as with the old brakes, but it stops WAAAAYYY better.
