Brake Fluid Capacity

[400SE Dave]

Putting braided brake lines on at the weekend and will change the Brake fluid to DOT 5.1 at the same time. Does anyone know the capacity of the system?

Thanks in advance

Don't know the capacity but I use about 2 litres by the time all the air is out.

IIRC the capacity is about 0.25 litres. I know that you need to get rid of the air but 2 litres???

Yes.

Easily put 2litres through mine at the weekend, and still no brakes so will try again next Saturday, plus hope to start engine and bolt body down. Just need to sort front springs then.

I'd agree - 2 litres.

Those 4 put calipers can be trick to get the air out of and new lines take much more bleeding effort than just a standard service bleed.

If you have some let - you can always do the clutch

Do you have good seals in the brake master cylinder?
If not, it could introduce air during the process of bleeding....
Perhaps less chance for this to happen when using an easy-bleed kit, but it will then start to show later.

If the brake system was empty and some pressure is built up, I pump the brake pedal (not completely to the floor to preserve the seals in the master cylinder) alot of times (up to 80-100 times) without bleeding, to get the air in the system moving towards the bleed nipples. And repeat this several times during the bleeding process.

Just a tip from my mechanic you should never pump the pedal if there is no fluid in the master, the seals can turn over on them selfs and then no pedal.
I do recommend the easy bleed kit, worth its money.
Ive seen me taking upto 2l of fluid to bleed the system to make sure there is no air in the brakes and with the engine off you should bet a hard pedal within a few presses, if you hold you foot on the brake and start the engine the pedal should drop about half an inch as the servo starts up.
this may be a stupid coment but check all your bleed nupples are at the top if not you will never get good brakes.
