Hi all Alfisti! It's my first post here.
After few years hibernation of my 75, I started to restore her to normal fun-drive function.
The first problem I have to fight with is stucked pistons in both, front&rear calipers. I decided to take out calipers, do the inspection, put the new seals in and bleed the system. I'm starting from rear ones, as it is more dificult, so if I beat all problems with rears - it should be big pleasure to work with fronts.
So, I raised rear and it's ready to work. My questions are:
1. If I remove rear calipers - may I let the fluid drain completely from hoses?
2. If yes - will the fluid leave "dynamic" circuit of pump almost completely? So there will remain very little amount old fluid in the circuit, I hope?
3. Will it be no problem with bleeding circuit, after filled the empty system again with new fluid? Reading diagrams, it looks like no problem. Electric pump should take the new fluid from tank, and then "push" it to calipers(while brake pedal is pressed). Anyone did like this before?
4. What about abs electrovalves system? It's disabled on my 75(both warning lights on ARC are blinking) - will it suffer from bleeding? Or will it bleed automatically while abs will activate(after few circles of electrovalve activation)? But if ABS is disabled yet - should I care?
I'll be glad for any tips or advices, cause I don't think I'll get help from anyone here in my town, where people do big WOW, because they first time see a car WITHOUT rear brakes.
