Can faulty brake boosters affect brake pad and rotor wear?

Hi, recently my 2011 Jeep Grand Cherokee 4x4 has been issued 3 safety recalls from Chryslers over the past 5 months. Brake booster, sun visor and fuel pump. The biggest one is the brake booster recall P14. I had it checked in july this year at the dealership and they said that it passed the pressure test (reading at that time was 0.9 and failing value was 0.11 so they still considered it 'safe' to drive) so only the shield needed to be ordered. At that time they also informed me that my rear pads and rotors needed to be replaced because the rotors were warping and there was only 1 mm left on the pads. I had a brake inspection done, then had to pay to have them replaced because they're considered a 'wearable item' and not covered under warranty. My jeep only has 32,000 miles on it so I asked them why the rotors would warp so fast. They said it can depend on the driver. Mind you I had a grand prix for nearly 10 years that had 210,000 miles on it and those only were replaced once ! So its not my driving that caused them to wear, there's a defect. So I asked the dealership if it could be a result of the faulty brake booster. They said no. So this past October I was coming home from a trip and my brakes started not to work and I almost got in an accident because I couldn't stop right away. I had to get towed 190 miles back home and to the dealership. Sure enough the dealership told me that my boosters had failed (to mention, the shield part that was supposed to be ordered and replaced still hadn't been done yet). Now, it has been sitting at the dealership for a month now waiting on parts. They've also informed me that now my front pads and rotors need to be replaced. And that again is not covered under warranty. So what I need to know is if there's any possibility if faulty/failed boosters can have any affect on pads and rotors? I would think it could because if the boosters had been slowly failing over the past few months. That means more pressure needs to be applied to the brakes to make them work. But Chryslers isn't budging and won't even consider replacing them for me.

any information at all would be greatly appreciated.

thank you. Norah

With something like this call Chrysler and see what they say the tsb we have is about water intrusion and whether it will make it harder to work is anyone's guess. If dealer has given you a hrd time then see what cust service will do if anything. Call their 800 number
