How to Replace Polaris RZR 900S Front Brake Pads
Step 1. Remove the front wheel.
Step 2. Remove the protective shield from the brake caliper (if your Polaris RZR 900 model has it). The shield is secured with two T30 Torx bolts.
Step 3. Loosen the brake pad adjustment screw at the top of the caliper on the rear side, then back the screw off by a couple of turns.
Step 4. Remove the brake caliper assembly from the brake disc by taking off the two bolts securing the caliper mount to the wheel hub.
PRO TIP: Use a screwdriver to separate the brake pads and loosen them enough to slide off the brake disc if necessary.
Step 5. Retract the caliper’s pistons back into the caliper housing to make room for the new brake pads. Use a C-clamp to push down on the old brake pads to retract the pistons.
Step 6. Remove the old brake pads from the retaining pins and clean the caliper.
Step 7. Check that the caliper can slide back and forth on the mounting plate.
PRO TIP: If the caliper isn’t sliding freely, pull the mounting plate off the caliper, clean and grease the guide pins and pack the protective rubber boots with grease. The boots must be replaced if they’re torn or split. The two boots are slightly different, but you’ll find both types here.
Step 8. Install the new brake pads onto the caliper’s retaining pins and slide the caliper assembly back over the brake disc.
Step 9. Apply red threadlocker to the caliper mount bolts and torque them to 30 foot-pounds.
Step 10. Adjust the brake pad adjustment screw by tightening it in until it bottoms out, then backing it off by half a turn.
Step 11. Reinstall the protective shield to the brake caliper, followed by the wheel. Torque the wheel nuts to the correct pressure as specified in your Polaris owner’s manual.
NOTE: Aluminum wheels are typically torqued to 120 foot-pounds and steel wheels are typically torqued to 60 foot-pounds.
