I just did a massive brake job on my 4Runner, replacing all of this:
- master cylinder
- rear drums and shoes
- rear cylinders
- front rotors and pads
- and flexible brake lines with Wheelers Off-road lines
- plus replaced all the bleeder valves.
I bench bled the master.
I have bled the whole system 3 times now always starting with the passenger rear, then driver rear, then pass front, ending on the driver front.
After all this... My brakes are spongy!
When I press down they are "slow". It feels like there is air in the line that I'm trying to compress down and then the truck comes to a stop - but not immediately. I am just rolling down the street at about 15 MPH and its slllooooww to stop. For example, when I drive my Nissan Maxima, the brakes are snappy and tight. As soon as I give them a press, they grab! NOT so in the 4Runner.
I used the
Maddox Dual Vacuum/Pressure Hand Pump Kit, purchased from Harbor Freight. It holds a vacuum no problem. On the last bleed, I watched bubbles coming out then I got solid brake fluid.
Does anyone have any suggestions or tips?
Does the ABS have anything to do with my problem?
I watched Timmy's video to make sure I did it right...

The only difference is my 1998 4Runner doesn't require the key to be in the ignition to activate the brake booster.
