1996 Toyota Other

Hi.I have a Toyota Granvia.(MPV. Similar to the power van)
I needed to change the brake pads all round. They were low.
Discs all round. It went straight forward enough. The brakes worked fine before hand, and they are ABS.
I needed to push the piston back. On each caliper to allow for the new pads.
I put it all back together. And went to test brakes.
Before ignition. The brakes felt pumped. HOWEVER. When I turned the engine on. The brake went to the floor. With no brakes at all. Even after pumping. Very little to no brakes.
I thought I may have a leak. No.I've bleed all brakes. Very little air. No change to brakes.
Do you have any ideas?

The ABS seems tpo be the one causing the problem. Look for a sandy stretch of road and while driving at 20 mph, drpress the brake to make the ABS work. Try it a few times to see if it helps.
