    Have an old pickup that needs work. This is my fun winter project/learning opportunity. Most pressing problem is this. The brakes are very soft. You really have to mash them down to get them to work. Also discovered that at higher speed, braking pulls the truck solidly to the left.

    Thoughts? Direction to move in?

    Thanks,

    The most likely cause is air in the brake line on the side opposite of the pull. Try bleeding the brakes.

    Brakes 101.
    Soft petal, must pump them to finally get pressure - bled the air outof the lines by starting at the closest wheel first, work your self away from the master cylinder.
    Sinking petal, fluid leak somewhere or worn out master cylinder.
    Missing fluid, leak or suction drawing the fluid in to the engins intake via the power brake booster.
    Vehicle pulling either way when brakes applied, brake shoes are out of adjustment or tires are unequal conserning thread or size.
    Squealing noise, disassemble and remove the dust from the drum.
    Brakes 'pulsatring' dureing use, warped disc, remove and retrue at machine shop or auto repair.
    Grinding noise and roughness felt when useing brakes, missing fiber on contact point, park it until its fixed.

    This is alist of the most common problems, many more also apply.

    First thing to do is pull all the wheels and rear drums off, get in there with a nice bright shop light and see what ya got goin on in there. Check how much of the pads and shoes are left, leaks in the rear cylinders, broken bleeder screws, cracked caliper flex lines, heavy scores in rotors and drums, all the brake lines, leaks around the master cylinder, etc. If you're just learning the ropes when it comes to repairs, get yourself a manual for your vehicle.

    cheers,
