How to Replace Polaris RZR 900S Rear Brake Pads
Step 1. Remove the rear wheel.
Step 2. Loosen the brake pad adjustment screw, which is located at the rear of the brake caliper at the top. Back off the screw a couple of turns.
Step 3. Remove the rear brake caliper assembly from the brake disc by taking off the two bolts holding the caliper mount to the rear wheel hub.
Step 4. Press the caliper pistons back into the caliper housing to make enough room to install the new brake pads. Use a C-clamp to push the old brake pads against the pistons, which will press them back into the caliper.
NOTE: Don’t use the C-clamp directly on the pistons, as it may damage them.
Step 5. Remove the old brake pads from the caliper retaining pins and clean the caliper with contact/brake cleaner.
Step 6. Check that the caliper slides freely on the mounting plate pins.
PRO TIP: If the caliper doesn’t slide easily, pull it off the mounting plate, then clean and grease the plate’s pins and pack the protective rubber boots with grease. Replace the boots if they’re torn or split. The two boots are slightly different from one another, and both can be found here.
Step 7. Install the new brake pads onto the caliper retaining pins, and slide the pads and caliper assembly back over the brake disc.
Step 8. Apply red threadlocker to the caliper mounting bolts and torque them down to 46 foot-pounds.
Step 9. Adjust the brake pads by removing the brake pad adjustment screw from the caliper and applying a small dab of red threadlocker, then tightening the screw in until it bottoms out and backing it out again by half a turn.
Step 10. Reinstall the wheel and torque the wheel nuts to the correct force.
PRO TIP: Aluminum wheels are typically torqued to 120 foot-pounds and steel wheels to 60 foot-pounds. Check your owner’s manual or the Polaris website for torque settings for your exact RZR model.
