XJR brakes are a weak point

The pedal feel is a bit soft on the X308's but the brakes should bite properly once they're applied hard. When I stand on my XJR's standard brakes from a high speed, they haul the car down pretty well for a big saloon.
A slightly soft brake pedal feel by design is not the same as brakes which don't work properly because there may be a fault present. Check the thick vacuum pipe to the brake servo for leaks.
Incidentally, princemarko, your other thread mentions the random engine management faults you're getting with the restricted performance mode & fault codes appearing.
Now you say that you have no confidence in your brakes-so I'm thinking that the 2 faults are related.
If you have a faulty vacuum pipe to your brake servo-or even a faulty/internally leaking brake servo-you will get poor performance from your brakes & any brake servo/connecting pipe vacuum leaks will also allow unmetered air into your engine & cause all the engine management problems you're also getting.
I think you need to check your brake servo & especially the thick connecting vacuum hose for air leaks...
