It is possible the problem is ABS related but could equally be a problem with the vacuum servo or brake booster or the "supply" of vacuum.

Certainly best practice would be to begin by ensuring the brakes at each wheel are in good order.

Test the brake servo by pressing the brake pedal vigorously several times while stationary with the engine off. The pedal should then feel higher than usual and rock-hard.
Apply the footbrake with a moderate force and start the engine without using the accelerator pedal, if possible. The brake pedal should be felt to pull itself down under your foot immediately the engine starts and stop pulling down in just two or three seconds, maybe just a second or two more if it is a diesel model.

Release the brake, allow the engine to idle for a few seconds longer and switch off. Listen carefully in the resulting silence for the sound of air leaking. This might have to be repeated several times in order to listen under the dash and in the engine compartment around the brake booster and vacuum lines. A short piece of garden hose used as a listening tube can be useful.

Once a servo has been charged with vacuum, in the absence of leaks, it should remain charged for a long time if the brake is not used - certainly hours but often months or even years is not unusual. Aplly a moderate pressure to the brake pedal and a shhhhh... sound should be heard that lasts about a second and then stops. Increase the pedal pressure and another shhhh sound and stop.

If all tests ok you can be reasonably confident the brake booster and vacuum lines are in order though it is still possible the vacuum supply is insufficient for sustained braking. A road test on a clear and safe downhill route will determine if this is so. Make a rapid series of brief brake applications at a constant speed of around 30mph and the braking effort and the feel of the pedal should remain consistent and if it does not it indicates restricted supply pipes or hoses, poor engine tune, incorrect idle speed (petrol models) or a worn or inefficient vacuum pump if it is a diesel.

there will be a drain pipe in tat area that drains the air box under the windscreen
the brown color could be rust
It is a high rust area as it collects the salt water from the roads and any leaf , clutter dirt etc which stays moist and sets up the rust process

There is no need to bleed the filter unless it is a diesel, and this car doesn't come with one here in the USA

I had the same thing here, I paid lots of money to find out what is the problem, mechanics played with my poor car damaged everything they can to stop it from running, but when I found out that when I changed the battery on my own, with a turkish manufactured battery of 100 A big battery, not even the fault stopped appearing but all the car was boosted in performance, Dsc not available and Park Brake is all related to the level of electricity running the parts of car was screaming back to you, change my battery, all parts of Jaguar runs on electricity, main computer now runs faster, no delay on screen, and now Dsc not available once ignited doesn't appear anymore, remember that once car is reset by battery change, you need to apply brake and boot (step on brak and hold park brak lever up at the same time with pressing computer button on stearing whisk for like 10 sec until you see on screen AVE back again), and bypass radio lock by pressing on the three buttons, mem and the right combination with >>, and you're set
