    You may have a major brake problem. First try to remove the ABS fuse this will disable the abs and not allow it to kick in. if symptoms continue you should do a full inspection of the braking and drive line. BTW never kick the truck to reverse well moving forward you will ruin your tranny.

    I only put it into reverse after a have completely stopped and I repaired the abs wire but the parking brake light and abs light is still on do you think it could be because I have no guts in that drum that blew up?? And IM tuning on 3 brakes atm I need this fixed by Tuesday as I am starting a new job...

    it sounds like you blew a rear wheel cylinder. What do you mean you have no guts in the drum? Did you take parts out?? The lights are probably on because you are low on brake fluid. You need to have someone look at it! Like conlan said, there is something crazy going on there if the front tire is "randomly locking up" while driving and you have to go thru a complete procedure to get it unlocked.

    Yes all the part are taken out of the drum and the line to that drum is blocked off temporarily and no IM not low on brake fluid....but yes the rear wheel cylinder also blew up but all of the springs and everything fell out when,I took the drum,off....and the tires were locking up because my abs wasn't getting a proper reading due to my abs wire being broken (fixed that tonight) I've been around enough vehicles to know my advanced engine/ drive train and electrical but not drum breaks...as 70% of dragsters have disks all around....but yea.... IM going for my parts tomorrow and my buddies a GM tech he's gonna help me fix it...

    Get it fixed before it damages other parts and you kill some one when the brakes go out. Also when you got the drum off check your axle seals because they eventually go and leak axle grease ruining the drum lining, this is from personal experience. Just get it fixed because every time you hit the brakes you bleed fluid out.

    You posted just before me so now my statement is invalid.... Ok well still it stands you NEED to fix your brakes. Also the drums GM used in the 90's are fairly advanced plus they are abs drums.

    When you stated that they randomly locked up. Did you mean while braking or just driving? I took it as while driving.

    If it were me... I'd also replace the bolt and sliders for your front calipers as they always get corroded and stick causing the calipers to hang up.

    I agree. That would be AFTER I put the back brakes back together.
