I have a 2006 land Rover LR3 and it been having alot of issues due to two suspension air bags that both have tares and it's both rear and front driver side so it throws alot off on the car like the lights on the dash because it can't get to the correct height. I also have a small coolant leak I see under my truck but the last two days when I drive it, it's louder like a exhaust leak but the noise doesn't change when I accelerate and then when I'm coasting down hill it's like I'm slowing down as if my brake pads locked !! But after driving a bit even on the highway I'm not smelling burning brake like I thought I would if the the pad was stuck down !! Is there a way I can see if the pad is stuck without taking apart the car??? I'm single Mom and not going to actually take the tires off but a heads up so I'm not taken advantage of at the garage would be the best !! What could this be there's no lights coming on to tell me anything is wrong just the coolant level low light which must be a broken floater because the coolant reservoir is full !! Thank you for any type of information that can help me !! And other things was that I think I'm over on my oil change I think the garage wrote the wrong amount of miles like 10,000 instead of 5,000 as I'm also noticing horrible gas miles and I only use premium gas !!!
