Bought an MTB and it has these fins/wings on brakes, can’t figure out what they are or what they do. Any ideas?

Heat dissipation
fins that dissipate heat from the braking surface to prevent brake fade on long descents
Those are radiator fins, ostensibly to help reduce heat.
I’m not sure how well they actually work – the reviews and forums I found in a quick search seem very mixed, with them really only being needed for specific edge cases.
your brake calipers are incorrectly installed, the self-aligning washers go on the outside of the caliper, not the inside
Aftermarket pads. They are a monstrosity. Swap for regular Shimano finned pads.
Heat sinks to prevent the pads and rotors from overheating on steep long descents
I’d really like to see a simulation of these things under the expected thermal load to see how much of an effect they really have. Those fins look way too thick to be very efficient heat dissipators.
We are cooked….
Seems like a dissipator, like on some PC gaming component that have useless dissipator.
Next step will be RGB rainbow LED…
Heatsink. Problem is very little heat is transferred to the pad when braking, friction material is a poor heat conductor most of the heat is transferred to the coldest part, the brake disc to be dissipated.
It’s not even in the airflow.
The real versions are part of a lineup called Shimano Ice Tech. I had some when i used to run saints and my brakes didnt overheat doing race runs down morzine wheras lots of other models did. Only time ive ever seen evidence of them being useful. Maybe for ebikes too ig.
Heat sink to help cool the brakes.
Difficult to see but it seems too far away from the parts that get hot to be very effective.
Ostensibly they would be for heat dissipation, but realistically, they don’t do anything
Plasma shield generators
I see you’ve been helped regarding the brakes
It’s A MTB, not AN MTB
You wouldn’t say “I got an mountain bike yesterday”
Cheers
