so fluid is coming out at all fours?
Lame jokes pulled from circa '2000' Motor magazine aside, I have replaced everything in the corona's brake system bar the metal lines, booster and front rubber lines.
Have bled it and the pedal goes straight to the floor still, has absolutely nothing.
When i got the car 3 months ago it was fine, brakes worked but since it wasnt rego'd i took it to the shops twice and they got slightly spongier, then i swapped to RA60 calipers, rebuilt them, new rotors, pads, new rear wheel cylinders, machined drums, new drum shoes, then i bled them and they were barely working.
I get the car home, bleed them properly (starting with the furthest away wheel from the brake master) pedal has pretty much nothing again, pop the bonnet and there is brake fluid pissing out between the master and booster. Fuck. Completely rebuild the master, new stainless steel piston as the iold one was pitted, new gasket, $260 bucks later, bolt it up tonight, new fluid, bleed, absolutely nothing again.
I can pump the pedal up and it gets harder, i can visually see the master sucking in fluid as the pedal is depressed but then when released it forces the fluid back up the reservoir and bubbles like there is a clot in the lines and there is a lot of pressure behind it.
All vac lines are still connected to the booster and it seems to be working perfectly.
Anyone got any ideas?

Could have a real small leak, the same thing happened with mine replaced the master the rear slaves and bled the system countless times. After a week or so i saw that a small amount of fluid had diappered from the resivoir, but hardly anything. so i sussed all the lines for leaks and couldnt find anything at all, then after a couple of weeks of driving the hole must of expanded from the fluid pressure and i noticed it was losing a fair bit more fluid, turned out i was a leak in one of the rear solid lines only found this out though when the sack got defected and was off the road ahh well.
Yeah? Ill get under it tomoro and sus it all out but would have thought that the fronts would still work even if the rear line had a leak in it. fuck knows.

yeah the fronts should still work for sure, did you bench bleed the master? but even if you didnt it should bleed up alright, thats all i can think of.
Nah just chucked it on and bled the brakes, it seems to be working fine tho, it must be if fluid is still coming out the bleed screws.
Im thinking the actual calipers are fucked or something, maybe i rebuilt them wrong, tho they werent that hard to do and everything seemed to fit ok.

Sometimes when you rebuild calipers you need to have them honed. Maybe chuck on some calipers you know are good if you can and try again ?
cailpers right way up?
As in have the piston bores honed?
Calipers are the right way up im guessing, the bleed nipple is at the top.
