    i just recently swapped hydroboost onto my truck and the pedal is kinda vibrating like warped rotors, but they are newer rotors on there and i dont remember it doing that with the vacuum brakes. i have a very firm pedal thanks to the garden sprayer bleeder, but it is pretty annoying that the pedal is not smooth. any ideas?

    Too much pressure, or maybe varying or insufficient pressure, from the PS pump.

    Did you do any of the hydraulic-steering mods to the pump, by chance?

    Might be inadequate return lines -- does your reservoir have two pipes, or did you tee into one on it?

    Anyway, you're right, it's a problem on the power steering side and not the brake side.

    Oh, and bleed your PS system good -- jack the wheels off the ground and go side to side like 20 times, checking fluid level as you go.

    BTW, the garden sprayer bleeder is the shiznit, IMHO. :deal:

    its a metal plate with gasket material on the bottom, with a nipple in the plate and a hose from the niplle to the garden sprayer, you clamp it to the top of the resivoir and pump the sprayer that is filled with brake fluid, you then take a pice of clear hose to all your bleeders and open them until fresh fluid and no bubbles come out, then move on to the next one,the best invention ever thought of, i will never pump brakes again

    i was talking about the ps fluid, there isnt an issue with the brakes not working, they are there and the pedal is awesome, i power bleed them recently and new fluid throughout.

    I agree. I think there may still be air in the PS system too. One thing I do when bleeding a PS system, as well as putting on jack stands and turning the wheels back and fourth, is to turn the wheel to full lock one way, and shut the engine off for 15-minutes and let it sit. Then do the same for the other full lock side. This is somthing I learned during some factory training I recieved from Saginaw Michigan. Also, make sure the lines from the booster to the pump or on the correct in/out return sides.

    Duh :doah: Wrong thread... what WAS I thinking?

    Yeah, bleed the PS system, and check that the PS pulley is parallel, the belt is tight, etc?

    That sounds like a good idea...it makes sense too. Next time I bleed the power steering, I'll try it out. Thanks for the tip!
