ABS module & Brakes
I have a 94 V6, and I'm putting a disk rear end of a 2000 Firebird, When I go to purchase some brakes do i have to get 00" Firebird brakes or can I get the 94 brakes??
Another question, My ABS module is either bad or is bad, does it matter if i get one that came off a drum or disk rearend,also i was told to use only 93-97 ABS modules. is that true??

Re: ABS module & Brakes
You have to go with the brakes off the '00 firebird. Actually any brakes from 98-02 camaros and firebirds. Otherwise you would have to switch the backing plates to the '93-'97 system. You will also need the all the E-brake cables and rear hoses from the 98-02, unless they came with it when you bought it.
That rear should be set up as a 4 channel abs system, so the 93-97 module wont work. Im not sure if the 98-02 module would work either, because of the abs computer in the vehicle. Tough situation there. The 93-97 rear has the abs sensor in the pumpkin, the 98-02 has 2 abs sensors, one at each wheel

Re: ABS module & Brakes
The ABS (only) cars have the single wheel speed sensor on top of the differential housing (3-channel). The ABS + TCS cars have a wheel speed sensor on each end of the axle housing (4-channel). Beginning in 95, the F-Body was available with traction control, so the rear axle assembly had a 3-channel rear as the standard, and a 4-channel rear that came when the optional TCS (TCS on Firebird = ASR in the Camaro) was selected. 98-02 cars also had 3-channel system for ABS and 4-channel for ABS + TCS.
So, since the 94 did not have TCS available, he needs a 3-channel rear axle from any year - 1993 through 2002.
If the 2000 axle has the disc brakes intact, you would buy replacement parts for a 2000. Note that the e-brake cable setup is different between the 93-97 rear discs and the 98-02 rear discs, and will have to be reworked to put a 2000 rear in a 1994 chassis.
The EBCM (electronic brake control module = the ABS computer) interfaces with the PCM, and has to be compatible. That would seem to require that a 94 chassis/PCM requires a 94-97 EBCM. If you mean the ABS motor assembly, that needs to be 3-channel, and I don't know if you could mix one from a drum brake car with your disc brake rear.

Re: ABS module & Brakes
Thanks for the help guys!! Got the rear end in, lowered, but that damn ABS is still on, So if worse comes to it just deal with the ABS INOP light being on?? If I can find a shop out here in AZ that can fix my situation, ill let you guys know. 1994 Camaro with 2000 Firebird disk rear end?? I hope I figure this out soon.
