Broken Brake Cooling fins
« on: 26 Jan 2023 at 19:18 »
So I started cleaning up the 90+ today, a good jet wash has revealed the cooling fin ring part on the front brake has cracked, I'm guessing this is a cast alloy rather than a machined alloy part?
Does any one have a spare good one or know if this one could be repaired?
The material looks to be fairly fragile and degraded around the break.

Whenever I run into a problem like this, I take it to either the local aircraft welder
(there is almost always one at smaller airports) or the local stainless guy - who is a bike enthusiast.
They can usually advise how to proceed further.

It will require some considerable cleaning to be weldable.
But may just be possible without unlacing the wheel - if those fins are not structural.
A dab hand with a mig will probably do it in 3 or 4 short bursts, so as not to overheat things.

A quick google in your vicinity turns up these 2

As long as its not structural ...
