is.i check the fluids and everything seems fine.it almost cost my life twice and
im scared driving my land rover already.i drive it everyday and the brakes fine
but absolutely made me think twice going up any mountain already.....i need your

Answer
Hello William,
A good brake inspection would be required on your vehicle to be safe. Make sure the discs,pads ,calipers and all linings are ok. But from the symptom you described. It seems like you might have air or water in you're brake fluid. I recommend you flush and replace the brake fluid.
Hope I was of any help
