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, a product such as Permatex® Disc Brake
Quiet 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 Brakleen or
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)
Adjust pad stop
Insufficient lever or pedal
clearance
Set to proper level
Master cylinder reservoir
overfilled
Check brake fluid level,
adjust as needed
Master cylinder
compensating port
restricted, Master cylinder
piston not returning
completely, Caliper piston
(s) not returning
Clean piston(s) seal
Operator error (riding the
brake / park brake
applied)
Educate operator
Loose wheel hub or
bearings
Tighten wheel, hub nuts or
replace bearings if worn
Brake disc warped or
excessively worn
Replace disc
Brake disc misaligned or
loose
Inspect and repair as
necessary
Noise is from other source
(chain, 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 (if available)
Brake Bleeding / Fluid Change
NOTE: When bleeding the brakes or replacing the
fluid, always start with the caliper farthest from the
master cylinder.
CAUTION
Always wear safety glasses during these procedures.
Brake fluid will damage finished surfaces. Do not allow
brake fluid to come in contact with finished surfaces.
NOTE: Do not remove brake lever when reservoir
fluid level is low.
This procedure should be used to change fluid or bleed
brakes during regular maintenance.
1. Clean reservoir cover thoroughly.
2. Remove screws, cover and diaphragm (C) from
reservoir.
3. Inspect vent slots (A) in cover and remove any debris
or blockage.
4. If changing fluid, remove old fluid from reservoir with
a Mity Vac® pump (PN 2870975) or similar tool.
