BRAKE SYSTEM SERVICE NOTES
Disc brake systems are light weight, low maintenance, and perform well in the conditions this vehicle will routinely encounter. There
are a few things to remember when replacing disc brake pads or performing brake system service to ensure proper system function
and maximum pad service life.
• Optional pads are available to suit conditions in your area. Select a pad to fit riding style and environment.
• Do not over-fill the master cylinder fluid reservoir.
• Make sure the brake pedal returns freely and completely.
• Adjust stop pin on front caliper after pad service.
• Check and adjust master cylinder reservoir fluid level after pad service.
• Make sure atmospheric vent on reservoir is unobstructed.
• Test for brake drag after any brake system service and investigate cause if brake drag is evident.
• Make sure caliper moves freely on guide pins (where applicable).
• Inspect caliper piston seals for foreign material that could prevent caliper pistons from returning freely.
• Perform a brake burnishing procedure after installing new pads to maximize service life.
• DO NOT lubricate or clean the brake components with aerosol or petroleum products. Use only approved brake cleaning
products.
BRAKE NOISE TROUBLESHOOTING
Dirt or dust buildup on the brake pads and disc is the most common cause of brake noise (squeal caused by vibration). If cleaning
does not reduce the occurrence of brake noise, Permatex™ Disc Brake Quiet (PN 2872113) can be applied to the back of the pads.
Follow directions on the package. This will keep pads in contact with caliper piston(s) to reduce the chance of squeaks caused by
dirt or dust.
Brake Noise Troubleshooting
Possible Cause Remedy
Dirt, dust, or imbedded material on pads or disc
Spray disc and pads with CRC Brakeleen™ or an equivalent
non-flammable aerosol brake cleaner. Remove pads and/or disc
hub to clean imbedded material from disc or pads.
Pad(s) dragging on disc (noise or premature pad wear) because
of improper adjustment
Master cylinder reservoir overfilled
Master cylinder compensating port restricted
Master cylinder piston not returning completely
Caliper piston(s) not returning
Operator error (riding the brake)
Adjust pad stop (front calipers)
Set to proper level
Clean compensating port
Inspect. Repair as necessary
Clean piston(s) seal
Educate operator
Loose wheel hub or bearings Check wheel and hub for abnormal movement.
Brake disc warped or excessively worn Replace disc
Brake disc misaligned or loose Inspect and repair as necessary
Noise is from other source (axle, hub, disc or wheel)
If noise does not change when brake is applied check other
sources. Inspect and repair as necessary
Wrong pad for conditions Change to a softer or harder pad
