hi iam new to landyzone my first post and problems first 1 drove through some deep water and now there is like a water bubbling noise when i brake and second problem there is a knocking noise from the rear of the car when accelerating or turning a corner even though had all three rear diff mounts changed any advice would be great thanks luke

sounds like you may have got water ingress into your hydraulic fluid and its boiling off when the brakes get hot? long shot but im thinking aloud.
Can you tell us where you hear the bubbling coming from?

Rear knocking...check your subframe mounts: [ame=http://www.youtube.com/watch?v=0XyzOgRz1-0]freelander subframe creaking cracking noise - YouTube[/ame]

Hmm, possible vacuum leak in the brake master cylinder? not sure...is your brake fluid nice and full?

 

[lukefreelander]

yeah brake fluid is on max noise only starts when pedal is fully depressed

 

[joe27979]

any leakages behind brake pedal at all? If its only doing it fully depressed them I wonder if there is a pressure limiting valve that is relievinf fluid back into the system and thats what you are hearing? Maybe someone can give an opinion on this train of though?
