Driving the other day and the brake pedal starts to feel a bit soft and every now and then there was a loud click noise.
Had a look today and found the lining material had sheared from one brake pad.
So much for genuine Jaguar parts...

 

How old ......

 

Those look well used and may have gotten hot. If its any consolation, be happy the pad was still there to remove, If not, you'd of eaten the rotor.
