    Spongy brakes. Need help.

    90 5.7L K1500 So last fall I replaced my rear drivers side wheel cylinder because the rubber boot on the old one started leaking.

    Brake Upgrades

    I just bought my first truck, 1998 GMC c1500. Brake pedal is really soft after changing fluid and replacing front pads and rebuilding the rear drums. Anybody know of kits that give it a little more stopping power that aren't crazy expensive?
