2018-2022 RZR RS1 Wheels and Brake System Inspection and Tire Rotation

Always wear safety glasses and nitrile gloves when servicing your Polaris RZR. To inspect the wheels and brake system and perform a tire rotation on your 2018 to 2022 RZR RS1, follow these steps:

1. Take a close look at each tire. 

• Verify there is sufficient tread depth. Tires should be replaced once they reach one-eighth inch or 3 millimeters of tread depth.
• Inspect for damage that may compromise the integrity of the tire.
• Inspect the tire pressure and verify it is set to specification. Reference the Owner’s Manual or tire pressure label on your vehicle for the correct specification.
• Take a close look at how the tires are wearing. If there is irregular wear, it may be time for a rotation.

2. Next, remove the tires. 

• Before the vehicle is off the ground, use a 19mm socket to loosen the lug nuts but do not remove.
• Safely elevate the vehicle. Reference your Owner’s Manual for proper lifting techniques.
• Remove the lug nuts and set aside. 
• Remove the wheels and set aside.
• Inspect the fluid level and condition in the master cylinder in the driver’s front wheel well. Ensure the level is between the min and max marks. Add fluid as needed from underneath the front storage compartment. Always use new brake fluid and do not allow fluid to contact painted surfaces or paint damage may occur. DOT 4 Brake Fluid is part number 2872189.
• Look at the banjo bolts on the inside of the master cylinder for leaks.
• Follow the lines all the way to both front calipers, looking for any leaks, kinks or damage. Ensure the brake line retainers are properly secured.
• Inspect the connections at the front brake calipers for leaks.
• Inspect the connections at the junction block in the driver’s rear wheel well.
• Follow the brake line to the rear brake calipers, looking for leaks, kinks and damage. Ensure the brake line retainers are properly secured.
• Inspect the rear brake calipers and connections for leaks. 
• If inspection reveals any concerns, do NOT attempt to drive the vehicle. See your authorized Polaris Service Center. 

3. Take a look at the brake pads and rotors. Always allow the brakes to cool completely before performing any inspection to prevent risk of burns.

• Measure the brake pad thickness using a suitable tool. Check the thickness on the inside pads as well and replace any brake pads that are worn beyond their minimum thickness of 0.180 inches (0.762 millimeters).
• Use a brake rotor measuring tool to measure the thickness of the brake rotors. Replace the rotors if they are worn below their minimum thickness of 0.268 inches (6.8 mm).

4. The tires can be rotated, if applicable, and reinstalled. Due to different configurations, some wheels may not be able to be rotated. Always pay attention to all markings and directional indicators on the tires.

• Install the wheels on the vehicle and hand tighten the lug nuts.
• Safely lower the vehicle until the tires begin to touch the ground. This will help keep the wheels in place when torqueing. 
• Torque the lug nuts to 120 ft-lbs (162.7 Nm) in a crisscross pattern. 
• Lower the vehicle completely.
