rental car accident without insurance
I got an accident on sat(23rd oct). I was driving rented car with my wife and 2 kids around 8:00PM on Mavis rd Mississauga and on red light brake did not work at all so i hit a car which was already stopped on red light. There are 2 possibility of brake not working at that time.1)could be mechanical failure in car
2)could be due to rain as we had rain in whole sat evening.
I did not opt for insurance coverage rental company provided and also do not have coverage on credit card. There could be damage of $4000-6000 on car which I was driving and 2000-3000 car that i hit. Now I am fearing rental company may claim lot amount from me. Please advise what can be done best in this case.
