Pads for drivers side are from a 1995 Dodge Dakota and the right passenger side are a 2001 what was changed out under my truck. I have had to purshase two different sets of brakes different sizes. Now the calipers need replacing. Do I have to buy a caliper for a 95 and for a 2001
You should make sure that both sides are identical, from suspension arms to hubs, brake discs, calipers and pads.
If not, then eccentric braking may be the cause of an accident and you may be liable if, and when, the insurance investigates.
You are responsible, in most places, for the safe condition of your vehicle.
I have only one thing to say about this you need to get this fixed as soon as possible,you are responsible for keeping your car in a safe state.
To put it simple for you get the right parts for your car unless you do so your insurance is not valid and your insurance company will not cover any type of damage to you-your car-or any damage to property.
Get your car repaired by qualified people that uses the correct parts and send the bill to the person/company where you got the car.
