What size rotors are on a 2008 Dodge Avenger?
The 2008 Dodge Avenger uses 11.1-inch (282 mm) diameter brake rotors on the front wheels and 10.3-inch (262 mm) diameter brake rotors on the rear wheels.
Detailed Explanation
The 2008 Dodge Avenger is a mid-size sedan that was produced by Dodge. When it comes to the brake system, the front wheels of the 2008 Avenger are equipped with 11.1-inch (282 mm) diameter brake rotors, while the rear wheels have 10.3-inch (262 mm) diameter brake rotors.
Brake rotors, also known as brake discs, are an essential component of a vehicle's braking system. They are responsible for converting the kinetic energy of the moving vehicle into thermal energy, which is then dissipated through the brake pads. The size of the brake rotors is an important factor in determining the braking performance and capacity of a vehicle.
Factors Affecting Brake Rotor Size
- Vehicle weight: Heavier vehicles require larger brake rotors to effectively slow down and stop the vehicle.
- Engine power: Vehicles with more powerful engines typically need larger brake rotors to handle the increased momentum and kinetic energy.
- Driving conditions: Vehicles used for towing, hauling, or driving in mountainous terrain may require larger brake rotors to handle the increased braking demands.
- Brake system design: The overall design of the brake system, including the type of brake pads and calipers, can also influence the optimal brake rotor size.
The 11.1-inch front and 10.3-inch rear brake rotors on the 2008 Dodge Avenger are well-suited for the vehicle's size, weight, and intended use as a mid-size family sedan. These rotor sizes provide a good balance between braking performance, durability, and cost-effectiveness.
What size rotors are on a 2013 Dodge Avenger?
The 2013 Dodge Avenger has front rotors that are 11.57 inches (294294294 mm) in diameter and rear rotors that are 10.31 inches (262262262 mm) in diameter. There may be some variation in specific models that could use slightly different sizes, such as 11.89 inches for the rear rotor, so it's always best to confirm the exact size with your vehicle before purchasing.
- Front Rotors: 11.5711.5711.57 inches (294294294 mm)
- Rear Rotors: 10.3110.3110.31 inches (262262262 mm)
What year to avoid Dodge Avenger?
The Dodge Avenger years to avoid are 2008-2014, with the 2012 model year being particularly problematic due to a high number of serious issues reported at low mileage, including transmission failures and a faulty heater system. Other years to be cautious of are the 2011-2014 model years, which have a recall for a faulty airbag control module, and the 2008-2010 models, which are known for numerous recalls and complaints.

Specific model years to avoid
- 2008-2014: This entire generation is known for common issues like failed blender actuators, transmission problems, and faulty heaters.
- 2012: This specific model year stands out as particularly bad due to frequent transmission problems and heater failures, with many issues reported at lower mileage compared to other years.
- 2007-2014: Common issues across these years include unreliable transmissions and failing heater systems.
- 2008-2011: These models had numerous recalls and common problems, including issues with the transmission and heater systems.
Key issues to look out for
- Transmission problems: Erratic shifting, slipping, and failure are common in both four-cylinder and V6 models.
- Heater failure: Many models experience heater failure, where the heater only blows air on the driver's side.
- Airbag module failure: The Occupant Restraint Control (OCR) module may short circuit, preventing airbags from deploying in a crash.
- Engine and electrical issues: Some models have issues with the engine stalling or not starting, which can be caused by faulty sensors or other electrical problems.
- Brake problems: Premature wear of brake pads and rotors is a common complaint.
What size socket for rotors?
The rotor is secured by the tire and wheel assembly, so you'll need a 19mm socket to remove the wheel nuts, a 14mm for the caliper bolts, and an 18mm for the caliper support. You do not need to remove the large axle nut to take off the rotor.
How do I tell what size my rotors are?
To measure a rotor's size, find its diameter by measuring across its center with a tape measure or caliper, and its thickness by using a micrometer or caliper at multiple points on the friction surface. For the most accurate measurements, remove the rotor from the vehicle first.

Measuring rotor diameter
- Method 1: Measure with the wheel removed
- Use a tape measure or a large caliper.
- Measure from one outer edge of the rotor straight across to the opposite outer edge, ensuring the measurement goes through the exact center.
- Method 2: Measure with the wheel on
- Use a large caliper or a method using a paper template with a hole for the hub to make an imprint on the paper, then measure the imprint.
- Another method is to use two magnetic markers attached to the rotor's surface and a tape measure to measure the distance between the magnets.
Measuring rotor thickness
- Method 1: Measure with the wheel removed
- Use a micrometer or a caliper.
- Measure the thickness at several different points along the friction material of the rotor to account for wear.
- Method 2: Measure with the wheel on
- Use a small caliper to measure the thickness in a few spots on the rotor's surface.
Other important measurements
- Hat height: With the rotor upside down on a flat surface, measure the distance from the base to the start of the friction material.
- Runout: Use a dial indicator to check for runout, which is an indicator of rotor wobble.
