    Brakes feel spongy

    So.... got the car back together, bled the brakes today, I used a vacuum system with air which literally sucks the fluid through the lines. Looks like I got enough air out, I bled till I saw no air bubbles and locked the nipple on each calliper. But the brakes feel a lot more spongy then with the original lines. Any tips, should I go to the garage and do another bleed sequence, I thought about running the car up on ramps and doing another bleed sequence. Any advice is appreciated.

    Did you bleed from the MC first? Do it again and then cycle the ABS pump, you may have air there. Read about pressure bleeding in SM.

    Better now, I did another manual bleed, I suppose I cycled the ABS pump when I was test driving it, there was some air and I no longer get that swoosh sound in the interior brake pedal when applied, now its firm and quiet to press

    When you say manual bleed, do you mean having someone pump and pressurize the brake, then opening the wheel cylinder bleeder valve? Or just gravity bleed?

    I used a vacume system with air supply, crack open the nipple with a 10mm and suck the fluid thru the line till its solid and tighten the nipple then refill the resovoir and start the process with the rest
