I have a 94 camaro 3.4l w/ drum brakes. I also have a 97 firebird w/ the Y87 pakage which has disc brakes and lsd. I swaped the entire assembly from the firebird to the camaro, ebrake cables and everything. I had my brakes bleed b/c I didn't have anyone to help me, but now my brake pedal has very little pressure. My question is there anything difference between the the pressure needed to operate disc brakes and drum brakes? Is there a proportioning valve I need to change or anything?

 

I put an LS1 rear into my 97 3.8 back in the day no questions asked, worked just fine.

 

^ but did you have drum brakes to begin w/? i just don't understand why the pedal is so low. there is no air in the system.

 

ttt?

 

5 dollars says theres air in the lines
