Thanks

I managed to get mine bled with 1L of ATE Blue with a little left over. You can see the colour change so you know when you have bled enough fluid through each line. I used a vacuum pump to empty the reservoir and filled it with ATE Blue fluid. Then poured the rest into a Motive Brake bleeder and bled the lines starting at the right rear, left rear, right front and left front in that order. Not going to be as easy to tell next time as the fluid will already be blue.

this is what the manual lists
page 392
0.53 US qt (0.5 l) MB Brake Fluid (DOT 4+)

a liter should do it if bled properly

i think ATC blue racing will change the colors after a while, so next time u do the changing u will notice , between blue and old fluid , or you can buy ATC fluid amber color, switch between.

I have motive pressure and planning to do it after remove my calipers and chagning my rotors.

Thanks

Aren't we supposed to bleed the brakes diagonally? Like rear right,left front then rear left,right front. I've read somewhere front and rear share the same diagonal circuit for safety measures. In case your front brakes fail they won't be all together. Since most of the job is done by the front you'll still have 1 front operational. Is it different on our car?

Ingenieur

it's usually front on 1 circuit, rear on one, on older cars...but with ABS there is a dedicated line to each corner and the master cylinder is usually 2 circuits, both feeding the ABS valve block

the usually sequence is longest line to shortest
RR
LR
RF
LF

but some mfgs have a different sequence, iirc Audi is the reverse

Start at furthest caliper from the reservoir, and work your way back.

One can of ATE Super Blue does the whole job. The bleeding order is usually longest line to shortest like others have pointed out.
