Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What type of brake system does the 2014-2020 Acura RLX use?
What type of brake system does the 2014-2020 Acura RLX use?
The 2014-2020 Acura RLX is equipped with a 4-wheel anti-lock braking system (ABS) with electronic brake distribution (EBD) and brake assist. The front brakes are ventilated discs, while the rear brakes are solid discs. The brake rotor diameters are 12.6 inches (front) and 12.2 inches (rear).
Q2 What is the recommended brake pad replacement interval for the Acura RLX?
What is the recommended brake pad replacement interval for the Acura RLX?
The brake pad replacement interval for the Acura RLX varies based on driving conditions and habits. However, under normal driving conditions, brake pads typically last between 30,000 to 70,000 miles. Always inspect brake pads during routine maintenance and replace them if the thickness is less than 3mm.
Q3 How do I check the brake fluid level in my Acura RLX?
How do I check the brake fluid level in my Acura RLX?
To check the brake fluid level, locate the brake fluid reservoir under the hood. The reservoir is marked with 'MIN' and 'MAX' lines. Ensure the fluid level is between these marks. Use only DOT 3 or DOT 4 brake fluid as specified in the owner's manual. If the level is low, inspect for leaks and top up as necessary.
Q4 What is the procedure for bleeding the brakes on a 2014-2020 Acura RLX?
What is the procedure for bleeding the brakes on a 2014-2020 Acura RLX?
Bleeding the brakes on the Acura RLX requires a two-person process. Start with the wheel farthest from the master cylinder (rear passenger side) and work toward the closest (front driver side). Use a brake bleeder kit and ensure the brake fluid reservoir is kept full during the process. Follow the specific torque specifications for bleeder valves (7.2 ft-lbs) to avoid damage.
Q5 Can I use aftermarket brake rotors on my Acura RLX?
Can I use aftermarket brake rotors on my Acura RLX?
While aftermarket brake rotors are available, Acura recommends using genuine OEM parts to ensure compatibility and performance. Aftermarket rotors may not meet the same specifications for heat dissipation, material quality, or durability, which could affect braking performance and safety.
