If you ever need to release the parking brake motor on a 2019 Nissan Altima with electronic parking braking system and don’t have a computer to do it, there’s a simple way to accomplish this using a regular brake caliper tool or a C-clamp. Let me walk you through the process.
Start by using a brake caliper release tool or a number five Allen key to release both screws on the top and the bottom of the parking brake module. After removing the bottom screw, rock the module back and forth until you can detach the motor apparatus.
Once the motor is off, you can manually push the piston back by emulating the spline gear with a T45 star tool. Spin the tool in a clockwise direction and push the piston back, alternating between spinning and pushing until the piston is fully retracted.
Remember to relieve the pressure by taking the cover off the master cylinder. Use a small screwdriver to tuck the boot back or lift it up to release any pressure. Then, make sure it’s tucked back properly.
After pushing the brake caliper back, gently rock the motor back in place. If it doesn’t line up, you can twist it a little bit to catch the spline. Reassemble the Torx screws, tighten them, and then you’re ready to reassemble after putting the pads back on.
And that’s it! You’ve successfully released the parking brake motor on your 2019 Nissan Altima without needing a computer. Remember to exercise caution and follow these steps carefully to ensure a smooth process.
