Hi,
FYI, a Copy of the Brake Pad Bedding Procedure taken from PAGID's Advert in the 2006 CDOC Performance Catalog:
Brake Bedding Procedure
Why Bedding?
● To Transfer a layer of Friction material onto the Brake Disc faces to achieve maximum performance.
● To stabilize compressible materials to avoid a
Spongy Pedal.
● To Boil-Off volatile elements in the Friction Compound in order to have the inital
Green fading during Bedding In and not in Actual use.
● To align the Pad surface with the Brake Disc surface to have full contact.
If Pads are not Bedded properly and/or are used hard right out of the box, they will likely become
Glazed. Pad Glazing is a condition where the resins in the Pad crystalize on both the Pad Friction surface and the Brake Disc surface, resulting in poor Stopping Performance, Brake Shudder, and Vibrations. Also, rapidly escaping volatile elements and moisture from the resin would seek an immediate escape route out of the Friction Compound, creating small fissures that would lead shortly to cracking and chunking.
1) Basic Bedding In
To initiate some heat in the Brake Discs and Pads
● 4 to 6 stops with Medium Brake Pressure from approximately 150km/h (90MPH) to approximately 80km/h (50MPH) - without allowing Brakes to Lock!
● Distance between each Brake stop approximately 300-400 meters (300-400 yards).
● The Pads should not reach temperatures above 400° C (550° F).
● No Dragging!
● Blocking any Air Ducts might be helpful to reach appropriate temperatures more quickly.
2) Immediately after Basic Bedding at High Speed
● One stop with Medium to Heavy Brake Pressure, without allowing the Brakes to Lock from approximately 180 km/h (110MPH) to approximately 80km/h (50MPH).
● No Dragging!
● Recovery Stops with light Brake Pressure 3 to 4 times. (Cleaning Procedure)
● Repeat the High-Speed stops, including Recover Stops, 2 to 3 times.
● Allow a Cool-Off distance of approximately 500m (500 yards) between High Speed Stops.
Brake Discs
If possible, Pads should be bedded on used, but NOT worn-out, Brake Discs. PAGID Brake Pad Material can be used either on Solid, Grooved, or Cross-Drilled Discs. For Disc Bedding, please refer to Disc Manufacturers' own instructions.
Mounting New Pads on Used Discs
Edges of Pad surface should be filed roughly to 45° to ensure that the Pad carries fully and evenly and is not touching the edge of the Disc. Do not use Discs which are
Pre-Bedded or have been used with Friction Material other than PAGID.
Now, obviously, at the speeds recommended, an appropriate road should be selected and sufficient caution should be excercised. If such conditions do not exists close to you, consider changing the Pads when you arrive at a suitable location. Hope this helps...
Happy Motoring!... Jim'99
