First 200 mi
Bedding in new brake pads is a one-time procedure: find a low-traffic road, do 8–10 moderate-to-firm stops from about 35 mph down to 5 mph, with 20+ seconds of rolling between each stop to let the pads cool. Then drive normally for 20+ minutes without hard braking. This deposits a thin layer of pad material onto the rotors, which is the actual contact surface that does the braking. Without bedding, you get noise, vibration, and weak initial bite.
🔎 Why Bedding Matters
REASON 01
Pad transfer layer
Brake pads and rotors don't directly contact - they slide against a thin layer of transferred pad material. Bedding creates this uniform layer.
REASON 02
Prevents pad glazing
Hard braking on cold pads with no transfer layer can glaze (overheat and harden) the pad surface, ruining the friction material.
REASON 03
Avoids brake shudder
Uneven pad deposits cause vibration in the brake pedal at highway speeds. Proper bedding lays material evenly.
REASON 04
Maximizes braking power
Bedded brakes have 20–30% more bite than un-bedded brakes. The difference is dramatic in panic-stop situations.
REASON 05
Reduces noise
Bedded pads run quieter. Skipping bedding can cause squeals, groans, and chatter that persist for thousands of miles.
REASON 06
Even rotor wear
Uniform bedding prevents the hot/cold spots that cause uneven rotor wear and the dreaded "warped rotor" pedal pulsation.
⚠ Don't bed-in on the highwayDon't do high-speed, full-pressure stops - that overheats pads before they're ready. The bedding range is 35–5 mph, firm but not panic-level pressure. And don't hold the brake pedal at the end of each stop - let the car roll a few seconds to dissipate heat evenly.

❓ Frequently Asked Questions
What if I forgot to bed-in my new brakes?
You can still bed them in - find a safe road and do the 8–10 stop procedure. You may need a second cycle to clean up any glazing from the missed bedding.
Does new pads + old rotors need bedding?
Yes - especially. New pads on used rotors may have an uneven existing transfer layer. Bedding helps the new pads adapt to the existing rotor surface.
Are ceramic pads different to bed in?
Slightly - ceramic pads can take 10–12 stops for full bedding, and they create less visible dust transfer than semi-metallic. The procedure is the same.
What about new rotors with new pads?
Same procedure. The rotors are clean and the pads are fresh - 8–10 moderate stops establishes the transfer layer.
Why do my new brakes squeal?
Likely from missed or incomplete bedding, or from a need for brake-pad shim grease at the back of the pad. Re-bedding often fixes light squeal.
How long until brakes feel "right"?
After bedding, brakes feel near-optimal in 50 miles and fully settled in 200–500 miles. Avoid hard stops in this period to let the transfer layer mature.
