Right replaced my beam last weekend, lost fluid while changing calipers ect. I've bleed the system 3/4 times now and when the engines off brakes feel perfect just like before. But soon as I start the engine goes instantly spongy. I've bleed it the old fashioned way and with a easy bleed kit both ways no air coming from any bleed nipples. I read on here about air trapped in the abs so took it to a gravel Carpark gave the brakes a good mash to get the abs working. Still no air coming out from nipples if I bleed it just nice clean fluid. So I'm stumped gonna take it to my garage I go too see if they can sort it, but thought best check with you guys as someone may have a solution for me.

Thanks in advance

Prob around 10 miles I haven't been out since I tried bleeding it again with the same result. Didn't want to chance brakes not working. I only changed the beam so I've still got same pads, calipers ect.

So weight up the back and bleed them? Car is fully striped and lowered but I did chop off a coil on the compensator?

Forgot to say that when the engines running and I press the brake down, I can hear air leaking sort of noise?
