Hardness in the brake pedal can because by low brake fluid. Air in the brake lines can also cause the pedal to push hard.
The brake light switch is out of adjustment.
Make sure you press down on brake pedal. If it's still locked, could be a transmission problem.
I would check the brake regulator switch, located under the dash near the top of the brake pedal. Its a silver piece that has a button like switch that activates every time you press on the brake pedal causing the light to turn on. It could be stuck in, causing the brake light to stay on.
Right next to the fountain of youth.
The power brake booster is probably at fault.
Check the upper end of the brake pedal under dash
if the brake pedal is hard you might first want to check if the mineral oil is full, get the castrol mineral oil for jaguars with the attached pump. Make sure the oil level is green with a black dot, if is clear with a black dot then the container is empty and it needs oil.,, Good luck bud..!!
look on the brake pedal you will see a lil switch there that's the brake light switch
yes, it's located at the top of the brake pedal
The brake light switch is located on a bracket behind the brake pedal support.
Attached to body behing brake pedal (if automatic) clutch pedal (if standard)
