"Bedding-In" your Pads
No, not sleeping with them!
When installing new pads you need to "bed" them in properly.
This means when you first install brake pads, braking is not at its optimal level (read "grippiest") until the pads create a small film layer between the rotor and the pads.
- After installing new brake pads, make 6 to 10 stops from approximately 30-35 mph applying moderate pressure.
- Make an additional 2 to 3 hard stops from approximately 40 to 45 mph.
- DO NOT DRAG BRAKES!
- Allow 15 minutes for brake system to cool down.
Your new pads are now ready to rumble.
Description and Operation OEM Braking System
Front and Rear Disc Brakes- The disc brakes are of a ventilated disc type which features high heat dissipation and superb braking stability. In addition, the front brakes quickly restores their original braking performance even when they get wet.
- Ventilated discs are used only on the front wheels.
- On STi models, ventilated discs are on both the frontand rear wheels.
- Each disc rotor, which is fitted on the outside of the hub, is secured together with the wheel using the hub bolts. This facilitates its removal and installation.
- The inner brake pad is provided with a wear indicator.
PAD WEAR INDICATOR
A wear indicator is provided on the inner disc brake pads. When the pad wears down to 1.5 mm (0.059 inch) the tip of the wear indicator comes into contact with the disc rotor, and makes a squeaking sound as the wheel rotates. This alerts the driver to the situation.
FRICTIONAL MATERIAL OF BRAKE PADS
The brake pads materials do not contain any asbestos which is harmful to human body.
Technical Service Bulletin
Brakes - Vibration Diagnostics
NUMBER: 06-32-03
DATE: 11/01/03
APPLICABILITY:
All Models; All Years
SUBJECT:
Brake Vibration Diagnostics and Revised Flat Rate Time
INTRODUCTION
The purpose of this bulletin is two-fold:
Studies confirm that rarely is it necessary to resurface Brake Rotors and/or Drums on all four wheels when a confirmed brake vibration exists. With proper diagnostics, front or rear brake vibrations can be isolated eliminating the need to resurface all four rotors and/or rear brake drums.
Warranty policy states that only the actual source of the issue is warrantable and preventative repairs for what might occur in the future are not a matter for warranty. Therefore, it is required that each brake vibration complaint be narrowed to the source and only that repair be completed.
ADJUSTMENT TO FLAT RATE TIME ALLOWANCES
With the introduction of on-car brake resurfacing equipment and even more recent advances of this equipment that reduce the times necessary for set-up / calibration, measurement and use, the flat rate time allowances will be reduced. The reductions in flat rate time allowances will become effective January 1, 2004.
Please provide the following information to the appropriate personnel at your dealership.
The labor operation numbers for brake rotor resurfacing on vehicles has not changed. Listed below is the new time allowance.
REPAIR PROCEDURE
Use the following procedure along with the troubleshooting chart.
Road test the vehicle to confirm brake vibration. If vibration is felt where braking, verify at what speed. Typically, front rotor vibration is felt at higher speeds (above 50mph) and in the steering wheel (circumference direction and/or side to side). If this is the case, the front rotors and pads will need to be inspected.
Typically, rear brake vibration is felt at lower speeds (below 50mph). Vibration will also be felt in the floor of the vehicle, pedal, seats and dash. If this is the case, the rear rotors and pads will need to be inspected.
To check for rear drum vibration, road test the vehicle at lower speeds. Be extremely careful not to lock the rear brakes. With the parking brake release button pushed in, pull the parking brake lever slowly and gently, which applies the rear parking brakes. If vibration is felt, the rear drums and shoes will need to be inspected.
Always refer to the applicable service manual for brake, brake drum, and rotor specifications. When resurfacing always check rotor/drum thickness before and after. These measurements must be noted on the repair order. If the rotor/drum is out of specification after resurfacing, it will need to be replaced.
BRAKE VIBRATION TROUBLESHOOTING CHART
Diagnostics:
Whenever diagnosing for vibration, the first items that should be checked are; worn and/or loose suspension components, axles, tire pressure, conditions of tires and check that all tires are of the correct/same size. In some cases tires out of balance can also cause vibration. Always refer to the applicable Service Manual for vehicle specifications.
