Sudden spongy brakes
Hi,
left for work this cold and snowy morning. Had to pop into my local Sainsbury's and had a bit of fun with the handbrake in the snowy car park.
got to work fine, but after work found that my brakes were spongy as hell. Pedal went to the floor first press then stiffened up after a couple of presses.
unfortunately this happened every time I went to brake.
does anyone know what is the problem?

You may have blown one half of your dual break system. I had that happen on an
old car. The pedal went mostly to the floor and the breaking was poor but it did
stop. Looking back to where it happened showed a splotch of break fluid on the road.
Made it home OK but going slowly.
Have a look to see if your break fluid reservoir is low or empty. If so then fill
it up and try the breaks and the leak should reveal itself.

Sorry about the late reply. Had an absolute nightmare with the jaguar locking wheel nuts and the key lost by previous owner. They have been finally removed and braided hoses are now fitted and bled thoroughly. But my brakes are still spongy. The clutch is fine so don't think it's that part of system. No visible leaks anywhere either.

If you know how to bleed the brakes, I'd do it yourself. I don't recall what fluid the X-Type requires but it's on the refill lid. You can use better fluid, but the only difference is the level of temperature it can handle and I doubt you will be pushing the car that hard and consistently to overheat them.
As far as spongy, bleeding and changing fluid as mentioned above is usually the place to start. Fluid does go bad eventually as it can absorb water and air in the line will cause your symptoms. Looking for/listening for vacuum leaks as also mentioned is also a good idea. The final thing would be to replace the master cylinder as it could be going bad as well.

And so the saga continues. Tried to flush the system today. Didn't expell the old fluid too well. Managed to bleed the rear right brake completely with new fluid. Then had issues with rear left and front right. Didn't want to bleed at all. Even took nipple out and still nothing coming through. Booster pipe ok though and no leakage from master cylinder either
