Spongy unsafe brakes!!!

[torched]

The brakes were working good. I just bought the truck and bleeding the brakes is the last fluid change I had left to do. I bled the brakes how it states in the manual and now they are spongy and unsafe to drive. I thought maybe it was the power steering pump since it was noisy anyway so I changed it. But they are still spongy. I got all the air bubbles out of the brake fluid and power steering fluid.

Any ideas?

Thanks

Here is what they feel like.

When the truck is off they are stiff. When I tun the truck on. Towards the last motion of pedal travel it's more like a rubber ball. Its also kicking back and pulsing.

Is there air in the hydroboost? If so what is the best way to get it out.

you got air!!, bleed bleed bleed

There was air in the hydroboost.

I jacked up the front of the truck and turned the tires back and forth. Also got a mighty max hand pump and rigged up a hose into a used power steering pump cap. My friend pumped the hand pump keeping 20 psi while I turned the wheel back and forth from lock to lock and lightly put pressure on the brake pedal. It took about 15 minutes to get the air out. Then I took a pair of needle nose pliers and crimped the hose for 5 minutes keeping the 20 psi in the hand held pump to equalize the pressure.

Hope this makes sense!

A good shop will be able to do a proper refill/bleed using pressure pump fill rig to ensure no air gets in

I just replaced my steering gear and i had air get trapped in the master cyl. After 2 days of driving fine, i went to stop and almost had nothing. Lost some power steering too. Shut it if at work and later went out and let it run with the power steering cap off to get out the rest of the air. That was not fun at all.
