On my last ride I overheated my rear brakes on a KTM 300 on a steep decent, to the point that they stoped working, should I be replacing the brake fluid now if the system got that hot, how often dose brake fluid need replacing anyway, could somebody give me some advice
Yes you should but get some motul 600 it has one of the highest boiling points of any brake fluid about $30 odd dollars for 500ml but well worth it.
