Stress Crack
ISSUEPads cannot slide freely or correctly within caliper
RESULTING CONDITION Warping of the back plate
CORRECTIONReplace pads, clean and lubricatecaliper brackets and guide pins
Uneven Wear on Pad Surface
ISSUEDeformed pad surface caused by irregularly worn or corroded brake disc (wear lip)
RESULTING CONDITIONBrake squeal, pulsing pedal, premature pad wear
CORRECTION Replace pads and rotors
Metal Residue
ISSUE
Water absorbed by porous rotorresults in release of metal fragments which embed themselves into the pad material
RESULTING CONDITIONBrake squeal, grinding noise, possible rotor damage
CORRECTION Replace pads and rotors
Charred Friction Material
ISSUEProlonged extreme temperature from excessive use or driver dragging foot on brake pedal
RESULTING CONDITIONReduced braking effi ciency, excessive deterioration and wear of friction material, abnormal wear
CORRECTIONReplace pads if friction materialis brittle

Glazed Surface
ISSUEPads are submitted to intermittent periods of excessive temperature. Inadequate break-in
RESULTING CONDITIONTemporary reduction in braking performance
CORRECTIONNormal use will restore braking performance. Replace pads if overly glazed or problem reoccurs
Damaged Back Plate
ISSUEFaulty assembly or disproportionate use of force during installation
RESULTING CONDITIONDecreased braking performance, noise, premature wear or pad can no longer be installed into caliper
CORRECTION Replace pads
Worn Out Brake Pad
ISSUELack of periodic inspections of pad wear and brake maintenance
RESULTING CONDITIONNoticeable squealing, grinding, vehicle pulling to one side when applying brakes, damaged rotor
CORRECTIONReplace pads, replace rotorif damaged
Contaminated Surface
ISSUEFriction material contaminated with brake fl uid, grease or oil during maintenance
RESULTING CONDITIONVehicle pulls to one sideduring braking and reducedbraking performance
CORRECTION Replace pads

Tapered Friction Surface
ISSUECrooked caliper, excessive caliper clearance, sticking caliper pistonor slides
RESULTING CONDI-TION
Friction material excessively and unevenly worn, uneven braking performance
CORRECTIONReplace pads, caliper maintenance and/or replacement
Corrosion
ISSUEVehicle unused for a longperiod of time or exposure to corrosive substances
RESULTING CONDITIONFriction noise, uneven wearof the braking surface
CORRECTION
Resurface the brakingcomponents (pads and disc)or replace the componentsif corrosion is too advanced
Unevenly Worn Set of Pads
ISSUEOne of the two pads cannot slide freely or correctly within caliper
RESULTING CONDITIONNoise and vibration during brakingand increased pad wear
CORRECTION Replace pads
