    The cheapest way to do it and to be sure you get all the parts you need go to a wrecking yard and get the whole brake booster, linkage rod, and master cylinder with all the bolts and hardware. It's an easy swap. Make sure you get one from the same year without anti-lock brakes. You could buy the parts new but you wouldn't exactly what all to order.

    I hate to tell you this but if your pedal is spongy there is still air in the system. You may need to power bleed the system to get all the air out. The reason the pedal is spongy is air compresses where a liquid does not.

    This is the same problem I am having with my 99 Suburban 2500 and the local Pep Boys (chain auto repair) has a $40 special where they flush the brake fluid. I asked them does this also include a bleed and they said yes. Anyone familiar with this procedure and know if it will cure my spongy pedal? Could it also be the master cylinder?

    Joe, my personal recommendation is that you take you vehicles to a mechanic rather than a corporate repair facility that is trying to make a sales quota. Rather than be drawn in for an inexpensive service and leave with a large repair bill, try a shop that has been in your town for 10 - 20 years that has a reputation for quality service. Google "pep boys complaints" and perhaps the 36 thousand hits will change your mind.

    If the brake fluid is dark and cloudy, I'd recommend a fluid flush. Either DIY, or take it to your mechanic.
