    The shaft on my power steering pump snapped. Belt keeps popping off so I can't drive it. Had to try my best to get a mile home and ended up towing it.

    Is there a belt that will work to bypass powering pump in a pinch??
    Is my system hydroboost??
    Can anyone recommend a good pump replacement??
    Are there any tricks to get the pulley off a broken shaft (if it's a PITA)??

    Anything else I should know or ask that I'm forgetting?

    you need to go rent or buy a gm power steering pulley puller, it will remove the pulley, and install it on the new pump, if you have hydro boost you pretty much have no brakes with no p/s pump. so if the pedal was rock hard, dont drive it till its fixed.

    Get an OE pump. Aftermarket for those things are shit.

    If you have hydroboost, you'll see a small cylinder next to your brake reservoir. If it's vacuum operated, your reservoir/master cylinder will be secured to a rather large, black, dome looking thing.



    My 2 cents; being that you're not sure what brakes you have, tells me you're maybe undertaking something like this for the first time. I'd let a pro take care of this one and start smaller

    This^^^..I did an aftermarket pump when I did my motor swap and I fought with the new pump every step of the way. I feels like it has air in it at idle, but works fine otherwise. I thought it was good preventive maintenance, but may pull it back off for an OE pump. Rent the puller for free from most parts stores..just remember how far the pulley is on the shaft so the new one is aligned properly.

    Got the pump changed, new pulley, everything's good... Except... When I press the brake for the first time on startup it does a slight pump on its own. Not bad but noticeable.

    Does this indicate a problem?

    if you have hydro boost brakes you may need to bleed the hydro boost system.

    lift both front wheels off the gound, then engine running, pump the brakes 20 times, then turn the engine off, but key to run and turn the wheels lock to lock 10 times.

    i like to put some cardboard under the pump as every time ive done this fluid is forced out the pump, cap on or off. thats air burping out.
