I have a 93 camaro with the 3.4 motor. Problem im having is im not getting any brakefluid pressure to my rear brakes.(both sides.) I checked the master cylinder and its sending pressure to the abs module. I get fluid out of both leeders on the abs module also. But, when I disconnect the rear brake line from the module and apply the brake i get nothing out of it. I DO get pressure for the front brakes out of the module though when i dsconnect them. So the poblem liessomewhere in the module i think.Icleared the computer before i did this also.Any help would be greatful.

 

Sorry but the only information I can offer you is a great deal on my abs stuff if you need it. Let me know.

 

I will keep you in mind. I have also been lookin on ebay for stuff....I just want to make sure its the right parts im troubleshooting. Manuals tell me nothing about the abs system and how it works with this car. Ive been trying to find some threads in this forum on this but not having much luck with it.

 

Per the FSM, if the ABS lite is on, you should not even try to bleed the brakes as you will introduce air in the system and mess up the good part also. You need to correct the ABS problem before bleeding the brakes, clearing trouble lights does not fix any problem. Do not change the module out till you find out what the problem is. You could have a bad sensor in the back telling the ABS that the wheels are locked and the ABS shuts off the pressure to the rear brakes. Get the system scanned with an ABS scanner.

 

Thats a good point. Now i need to find a scanner. I try my little plug in one but no codes come out of it. Has the ecm r abs switch on it. (scratchin head as to why no codes though)
