Help, need thread size for a broken bleeder valve on the rear brake....

If your bike is a GasGas, the thread is 10 x 1.0 .

You can see it on this link:

Hello APK,

If you are talking about the rear caliper bleed nipple, this thread is M6 x 1.0 (6mm diameter, 1mm pitch) The pre PRO models have a larger nipple arrangement.

If it has seized in place, be real careful when drilling out that you are precise in getting your 5mm tapping drill exactly in the centre, also you need to know how deep to go as the end of the nipple has a bevel surface that seats up against a similar bevel inside the caliper. Best to measure the new nipple first to gauge the drill depth so as not to cut past the origina bevel in the caliper.

Bye, PeterB.
