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?
