MATCO brake discs

[benjam]

Hi All,

Can anyone offer advice on the tool to remove the bolts from this MATCO discs?

Torx drive, but T27 is too small, and (next size up) T30 too big?

What would you replace them with if you accidentally flogged it out trying to tighten it up? The black bolt on the right is high tensile but a different drive head.

asking for a friend…

any advice out there please?

I had those internal-caliper Matcos for many years on my -6 and the rotors were retained by Allen button heads (like your black one). Just be sure to get new Nord-Lock washers.

It MIGHT be a Torx Plus

This is only a point-out, may not be correct.
Good Luck
