On arrival to my place, the ABS fluid level was just above the MIN.
Within this short period of the service, the fluid level is now above the MAX line so there is big leakage at one solenoid or small leakage from multiple solenoids.
There were lots of unpleasant looking debris at the bottom of the ABS filter and also some debris were observed at the bottom of the reservoir well below the filter.
Cleaned them to this level.
Also, as a pre-caution, it is my standard procedure to flush the ABS feed line if I saw any contamination at the bottom of the reservoir so flushed the ABS pump first.
ABS T-wrench and flushed the system by activating the inlet and outlet valves followed by just the inlet one.
As expected, 2 out of 4 solenoids were very leaky.
For now, it seemed to have stopped but please exercise ABS regularly from about 15mph when it's safe to do so before the tyre warms up.
Otherwise, the solenoid plunger seat will get contaminated again and start leaking.
Pressure bled the main brake hyd system.
Saw tiny bubbles on all four corners.
Glad we included this service after I saw the state of the brakes.
As my standard procedure, set the fluid level to here to indicate that brake disc and pad were re-used and not new.
For the ABS, this photo was actually taken after the test driving session but I'm going to keep the level at 1/2 and not at the max considering the two leaky solenoids.
