Brake Bedding/Burnish procedure

Jonnydz · 02-26-2019, 08:30 PM

Per the track prep guide it has us doing 75 brakes. Holly hell. Do I really need to do that many? And how often? Before every event or? Whats everyone doing? I am running a stock setup

Just once per set of pads.. If you change pads or rotors, you will need to repeat

Go on Ferodo website and follow their recommendation given their pads come with the car. A much simpler process, yet completely sufficient and effective.

Anyone else? How did u guy bed them before your first track day? Mine is coming up soon.

Do a few threshold braking events from 65-10mph and they will smoke a bit. 8-10 will suffice. The pedal will get mushy after those stops. Drive for 15 mins for the brakes to cool and they will be fine. Go to the track and have fun!

Basically what Stephen said above. I do mine just a bit differently starting with half a dozen 50mph to a roll (never stopping) at half pressure to create pad transfer onto rotors but avoiding glazing them. Then i do half a dozen 65mph to a roll with full and quick pressure. The latter will produce some fade and may produce some smoke. Both are fine. Then i get back to speed to cool things down for about 15mins without using brakes at all. Then park and dont set e brake if possible. You're done.

The fade is from boiling the fluid right? Does the mushy pedal feel go away after it cools down?

Most brakes I have worked hard, never quite have the same firm pedal feel again afterwards.

No it usually is pad fade vs fluid (if any). In other words the pedal remains hard and doesnt go down. Yes, everything returns back to normal after cooling. If you boil the fluid and pedal goes down best to replace fluid asap. But this shouldnt happen and hence no bedding in procedure ever calls for it.

I did not.

And here is instruction from Ferodo site, for high performance "tuning" (vs racing pads like DSUNO), which applies well to stock pads:
"A series of applications, building from light pressure (x 5 applications) to medium pressures (x5 applications) on a quiet road from slow (initially) to moderate speeds.

The applications should not be separated from each other by more than 30 seconds. There is no need for the vehicle to come to rest on each application.

Allow the brakes to cool (this will occur during normal driving anyway, but do not, for example, go straight into a steep hill descent as the first use of the brakes) and the pads will be bedded."
