How To Break In New Brakes
Breaking in, or bedding in, a new set of brakes is very important right after they have been replaced. Immediately following installation, your new brakes will most likely feel stiff and a little bit harder to use than you remembered.
How Will I Know When My Brakes Are Properly Bedded In?
Along with completing the break in process for your new set of brakes, it is equally as important to check your work and make sure that you have done so properly. Take a look at the list down below to find some tell-tale signs that your bed in efforts were a success.
How to stop brake squealing?
Anti-noise aerosol brake sprays can often reduce or eliminate an annoying brake squeal with worn brakes, but they won’t provide a permanent fix – and should not be used with new brake pads. The only surefire cure for most brake noise problems is to replace the pads (NAO and ceramic pads are typically quieter than semi-metallic pads), resurface or replace the rotors (a nondirectional finish helps reduce noise), replace worn, missing or corroded disc brake hardware such as pad mounting clips and anti-rattle shims, and to lubricate the backs of the pads, caliper mountings, slides and bushings with high-temperature brake grease.
What is brake quiet spray?
A. Aerosol “brake quiet” products can be sprayed on the face of the rotors to temporarily reduce brake squeal. The spray leaves a thin film on the rotors that reduces friction and helps dampen pad vibrations and squeal – until it wears off, then it has to be reapplied again. Advertisement.
How to clean anti-corrosion rotors?
If the rotors have an oily anti-corrosion coating, wash off the coating with brake cleaner or by scrubbing with a brush and hot soapy water. If a new set of rotors has an anti-corrosion phosphate coating on the wear surfaces, a few normal stops will rub off most of the coating.
What happens if rotors are not in good condition?
If the rotors are not in good condition, they need to be resurfaced or replaced. Also, the rotors must be clean. This can’t be emphasized enough because dirt, rust, grease, brake fluid or metallic residue left over from resurfacing the rotors can interfere with the seating process and cause noise, pad contamination and/or uneven braking.
Can you overheat brake pads?
One thing to avoid with new pads is hard panic stops or high-speed braking until the pads have fully seated. Slamming on the brakes with a brand new set of pads can overheat the pads and rotors, which can glaze the pads. This will make the pads noisy and reduce braking effectiveness.
Find an empty parking lot or street
All your break-in tests should be done in an empty area where you can reach speeds up to 65 miles per hour (mph) without traffic around. We’ve found that empty parking lots and streets are the best places to do this. So if you’re looking to break in those new brakes, find an empty parking lot as soon as you can!
Engage hard braking at 40mph
What is hard braking? Hard braking is when you press hard on your brake pedal. Driving schools consider this a bad practice. However, when you are breaking in brake pads, it’s a necessary step. Hard braking at 40mph allows you to engage the brakes and warm them up for more efficient use. When braking hard, avoid coming to a complete stop.
Go 50mph and jam the brakes until ABS engages
Much like step 2, you’ll have to employ hard braking with this step. In this case, once you reach 50mph, slow your car down hard and fast enough for the ABS to engage. Doing this will essentially wear down what needs to be worn down quickly.
Reach 65mph, then slow the car down to 15mph
If you feel like it would be safer to reach higher speeds, then do so with the right safety precautions in mind. After reaching 65 mph, slow the car down to 15mph as fast as possible without reaching a full stop. Full stops are detrimental to the new brake pads and their break-in period .
Let your brakes rest for 20 minutes
After any good exercise, a car will need a good cool down. Put your car in park and let it rest for about 20 minutes. This will allow the brakes to cool down and settle into their new form. So what’s happened at this point? You shaved off most of the parts that needed to be shaved off, effectively breaking in your brake pads.
Conclusion
Breaking in your brake pads is necessary to prevent brake rotor warping. New brake pads are always hard. Therefore, using them casually while they’re brand new may warp your rotors over time. This is completely preventable if you perform the steps mentioned above .
What Happens If You Don’t Break in Your Brakes?
If your brake pads are worn down unevenly, thus depositing the transfer layer unevenly, you will notice your car vibrating and shaking when you brake . This is due to the brake pads developing high and low spots where they have been worn more in certain spots than others. The high and low spots will become more and more exaggerated over time, causing the vibrating to worsen until you either have your rotors resurfaced, or you replace your brakes altogether. If you don’t break in your brakes, you’ll notice yourself needing to replace the pads and rotors more often.
How fast can you go when you break in brakes?
How to break in new brakes: Start driving, and speed up to 60 mph. Brake quickly to slow down to 20 mph. Immediately speed back up to 60 mph.
How to maintain brakes?
Keeping your brake full reservoir full and transport tubes clean ensure that there is enough pressure to squeeze together your brake pads when you hit the pedal, and your brake pads and rotors should be regularly replaced or serviced.
What happens when you apply pressure to brakes?
As described above, while applying pressure to the brake pedal, the brake pads are squeezing your rotor on either side and the entire braking system is heating up. The surface of the brake pads is wearing off of the pads themselves and being deposited on the rotor. This creates the transfer layer.
Why are brakes cooling down?
Your brakes, which aren’t in use, are cooling down as friction between the rotors and brake pads is decreasing. The cooling and reduction of friction in your brakes combined with the high speed to rotation in your rotor allows an even layer of brake pad material to be deposited.
Why is it important to break in brake pads?
Breaking in your brakes is important, because your brake pads leave behind a layer of material, the transfer layer, on the rotors due to the friction when braking. The initial break-in process establishes an even deposition of the transfer layer on the rotors, by letting the brakes cool down while the car, and the rotors, are still in motion. By establishing this even transfer layer on the rotors, you are also ensuring that the brake pads don’t wear unevenly.
How to wear down brake pads at 60 mph?
Once you’ve reached your target high speed of 60 mph, apply moderate pressure to your brake pedal . You should be pressing the pedal down about halfway to apply the proper amount of friction between your brake pads and rotor. This step is where you begin wearing down your brake pads and building up the transfer layer on your rotor.
