🛠️ Installation Tips
-
The "Banjo Bolt" Rule: Always use the new copper crush washers included with the set. Reusing old washers is the most common cause of slow fluid leaks and "spongy" brake feel.
-
Slider Pin Lubrication: While these come pre-assembled, it is a pro tip to apply a small amount of high-temp silicone brake grease to the slide pins. This ensures the caliper "floats" freely, preventing the inner pad from wearing down faster than the outer pad.
-
Bleeding Sequence: On Polaris ATVs and UTVs, always start bleeding at the caliper furthest from the master cylinder first. Keep the reservoir topped off; if you suck air into the master cylinder, you’ll have to bleed the entire system from scratch.
-
Parking Brake Adjustment: If your model has an integrated parking brake on the rear caliper, ensure the cable is slack before bleeding. Once the hydraulic system is firm, then adjust your parking brake cable tension.
-
Bedding the Pads: For the first 10–15 stops, use moderate pressure from low speeds ($15 \text{ mph}$). This "beds" the pads to the rotor, preventing glazing and ensuring maximum friction for the life of the pads.
🔍 Troubleshooting Guide
| Issue | Possible Cause | Solution |
| Brakes Dragging/Hot Hub | Seized slide pins or collapsed hose. | Ensure the caliper slides easily on its bracket. If the caliper is new but the brakes won't release, your rubber brake hose may be collapsed internally. |
| Spongy Brake Pedal | Air trapped in the line. | Perform a full system bleed. Ensure the bleeder screw is pointing UP during the process so air can actually escape. |
| Squealing After Install | Vibration or un-cleaned rotors. | Clean your rotors with brake cleaner. Apply a thin layer of "Brake Quiet" paste to the back of the pads (where they touch the piston). |
| Uneven Pad Wear | Misaligned mounting bracket. | Ensure the mounting bolts are torqued to spec. If the caliper sits at an angle, the pads will wear unevenly and reduce stopping power. |
| Low Fluid Warning | Leak at the banjo bolt. | Check the torque on the banjo bolt. If it’s tight and still leaking, the copper washers likely haven't "crushed" enough to form a seal. |
