Bed in brakes

[John Beedham]

I would just check that they are working or not … or not …. then decide … in 20 years of riding mtbs with disc brakes I have never had a problem with bedding in new pads or rotors… new or newly cleaned.

I know it's important to bed in new pads but when the rotors is cleaned is it any point to bed in again.

When you first bed-in pads it's to match the surface of the disc( groove/lines )
The only time you need to re-bed pads is if you sand down the pads .

I get mixed information looks like everyone have their own opinions or/and procedures.
Reckon I stick to the way I always have done - bed in new pads, no bed in after cleaning it works for me and I also stick to Galfer purple which for me last longer and give me better modulation and stop power in sunny and rainy days even though some say sintered pads are better when raining

100% with you on the Galfer purple. Found them the best around for wear and performance.
I'm riding in Northern Irish slop 75% of the year for the comparison.

This is a good read and explains a few things. ( to me anyway)

Mountain Bike Brake Pads Explained | Organic vs Metallic vs Semi-Metallic vs Ceramic

When replacing your mountain bike's brake pads, you might be confused with the vast amount of compound types. Picking the right type of MTB brake pad compound is important for the best performance and experience on the trail. Compound options are sintered metallic, semi-metallic, organic, and...

I probably use the mid compound for pads (Magura Preformance) and they seem to preform well for the type of riding I face.

The ceramic compound seem interesting though.

Agree, I`ll never ride again anything else than Galfer purple.

Shimano says:

To prevent noise and ensure the best performance, perform the bed-in procedure after replacing the brake pads or disc brake rotor.

How to perform bed-in
To optimize the performance of the brake pads and disc brake rotor, perform the bed-in procedure as explained in the steps below:
1. Ride your bicycle in a flat and safe area without obstacles and accelerate to a moderate speed.
2. Operate the brake lever until you slow down to walking speed. Do this only with one brake lever at a time. Be careful when performing this procedure. Always operate your brake lever with moderation, especially when you bed in the front brake.
3. Repeat steps 1 and 2 for at least 20 times for both the front and rear brakes. While repeating the process, the brake force will increase.

I had magura ebike pads .
Didn't last 2 months before they were down to metal with the conditions here in Northern Ireland.

I always wondered about this, because the same is of course true for car brakes. Now, is this done at the factory before the car is sold to the customer? Because if not, I suspect 99% of cars on the road have not done this procedure. I certainly never see people doing repeated emergency stops on the road...

I once followed the bed in procedure when fitting new brakes and pads on one of my previous cars, which required going out late at night to a deserted stretch of motorway and doing hard stops from high speed with my eyes glued to my rear view mirrors.

The advice there was to do something like 10 emergency stops from motorway speeds, but of course just bring the car to a crawl, not actually stop it. A good sign was supposedly to have smoke coming off the brakes by the end.

It does make me wonder though, if this is performed on all new cars at the factory... What about when people have their brakes replaced? I've never had a garage advise me to do this and doing so on public roads is very impractical.

After bedding my brakes in they worked no better or worse than the worn out brakes they had replaced, which suggests the bed in doesn't really do anything or that the car came bedded in from the factory.

If the factory doesn't do it, the people loading and unloading your new car at the port will do the initial bedding

How about bedding in pads when it's raining every day - possible or not?

If the rotor gets hot then yes.
