Bedding In New Brakes

[venomx]

Is it a myth or is it best to bed in new brakes ( discs and pads )  by going a certain speed, then braking and repeating this a few times ?
I hear it's only necessary on high end brakes

 

Is 50mph to 20mph a few times good enough, whilst leaving 30 seconds between each brake ?

Under normal driving conditions / circumstances no particular care or bedding In is needed. They may grasp a little bit on the first couple of times of use but after that they should behave as normal. I having riveted on new liners and heading down two miles of twisted steep mountainside narrow road with a full load on and I could smell the new liners burning 🥵😂. They hadn’t had the time to bed in.😂🤣.

No disc brakes on my cars in those days, but cars were simple to work on if you had a rudimentary knowledge of how things worked.

Brakes don't really need any special bedding in procedures as such, just take it easy with them and leave extra braking distance while they 'bed in'.

The idea is, when you put on new pads with old rotors (discs), the discs will be all grooved up, not smooth, and it takes a while before the brake pads 'wear in' to the grooves on the disc. Until that happens, you won't get full braking force under light/medium brake pressure as the pad will only be clamping against the top of the grooves, not the full face, so it's just a matter of being a bit more careful.

You can force them to bed in faster by doing a few hard brakes as you describe, but TBH it's not necessary and just a) wears down the pads prematurely and b) risks warping your brake discs by overheating if you do it repeatedly.

Last time I did that was on an Austin 7.

Don’t do this or you are risking to destroy your new brake parts. Just take it easy first 500 miles, avoid hard braking, and do check temperature if any excessive heat happening after driving, anything over 50-60 C° will indicate wrong fitting. Very important for brakes before fitted is all metal parts (hub, callipers) to be cleaned from any rust and brake dust, slider pins to be lubricated correctly and no any other grease to be used anywhere. Clean wheels mounting surfaces with wire brush too and torque tighten up the bolts to specs.
