what does it cost to fix brakes

It will need to be examined to see the extent of the problem. Cost depends on extent of work needed. Brake pads, brake rotors, Anti-lock brake sensors ect.... anything could be wrong. To replace front pads and rotors about 1.5 hours labor about 1.8 hours labor to replace rear pads and rotors. Rotors about $90 to $120 each brake pads about $55 to $70 a set.

If U take it to Jaguar dealer expect to pay close to $1000 for a complete brake job, new pads, disc fluid. Local brake shop can do the same job for less than half.
