    Brake and shift lever bolt question.

    Hi Gang,

    Getting ready to replace the brake & shift lever bolts.

    Is the best practice to heat the bolts prior to extraction?

    (I thought I saw a "how to" post in the past, but I couldn't find it.)

    Thank you!

    I don't know if it's best or not, but I applied heat to mine.... down a metal pipe to keep the heat localised. I believe it softens the sealing compound

    They are tightened to 22 Nm, so it should not be a problem for their extraction. I have never used heat to extrude those screws and they always work out fine.

    Conversely,  I know of a few owners who had them snap as they attempted to remove them !

    If it is true that the times I have been removing those screws, it was not because of a fall.

    Just do the one time solution and be done with them.
