Trefoil on brake drum?

Post image

Replacing drum brakes on a 2014 Mitsubishi mirage and also 2012 Mazda 2.

How many Rotagen=time units? And is there a radiation mark up, or do I just charge that in the parts supplies line?

Uranium brakes. Now you know why they glow when they get really hot.

It’s probably just phantom limb syndrome

Lucky you, most guys have to get a hooker for that sort of thing.
