i was driving a dodge 2500 on the highway when there was a sudden stoppage of cars in front of me, this was normal and i hit the brakes hard, they slowed me down to 10 mph but suddenly gave up stopping? i hit a mercedes in front of me and i cant afford to just pay the person for the damages to their car so i have to go through insurance. They said the accident is my fualt , even with the brake failure. Is this right?

I have the truck in the shop getting looked at right now so i can have a statement for my insurance company.

There is deffinatly something wrong with the brakes becuase now the pedal is very soft and i cannot lock the wheels or get them close to locking.
I took the car to the mechanic and he found a faulty master cylinder, he said it has likely failed just previous to the accident as it has not leaked much fluid at all.
and to my fortune, the cop saw the accident, and said i was following at about 10-14 car lengths.
idk about you but thats pretty far to not be able to stop

I got into an accident around the end of october last year. At the scene the other guy’s car only had surface scratches since he owned a Mercedes and the bumper took all the impulse, my car was pretty badly totalled in the front. The first thing I did after the accident was walk out of my car to check if everyone was ok, I asked him and he said he was. So we called the police, we didn’t ask for an ambulance or nothing because it was a low speed collision and we both had seat belts on. So the police officer came and took our reports, and asked me if I was ok I said I was and he asked me if the other driver was ok as well, and I told him he was, the police officer asked the other driver as well. Now one year after the accident this driver is trying to make a claim on being bodily injured in the accident. I can prove using physics and dynamics exactly how much force was applied to his seat and through the seat belt onto him, I have the police officer as a witness, how will my case hold up
I am 100% sure he is trying to fraud me, I am pretty sure he cut me off right before a red light but that cant be proven. However the police officer can testify that he was ok at the scene, how badly his car was damaged, etc; isn’t this enough to win a jury over? What is this other guy thinking, that I am so stupid I will settle for what he askes knowing I can win the case so easily because I am innocent and he will be commiting purgery on stand by lying about his injuries? Also doesn’t he get checked by an unbaised doctor recommended by the judge to show what his injuries can be attributed to? I have Gieco insurance, will they do anything to help me prevent this obvious case of fraud? Is there any chance that this guy’s lawyer can trick a jury even with all my proof and evidence?
Thanks for any ideas, also should I contact Gieco’s fraud department and report this as such a case for investigation?
Please help me, i dont know what to do now.
