hey guys, i have an AE85 with a strange braking problem that i would love to have some help with...
problem is when im driving the brakes pedal travels straight to the bottom b4 i get any amount of braking going on...i bleed all 4 wheels starting furthest first. when car is off the brake pedal feels as it should, when the car starts and the booster is activated i have to press all the way down for actual brakes...any thoughts...it feels as though there is air in the line but i bleed these things more than 3 times already

i have a new booster and master cylinder in as well, if that helps

With a new master there would be a lot of air in the system in less you bench bled it.
Also it would be leaking.
When you bleed the brakes you start @ the fairest point rear drivers side,rear passenger ,front passenger,drivers.I put the bleed hose into a bottle of brake fluid so as not to draw in air,also can see the air bubbles,when no more you knew that wheel is good!
Hope this is of some help!
