• I'm new to the world of disc brakes & getting a bit confused.

    Bike has only done about 500km but in often fairly grubby UK off road conditions. Noticed by the end of a ride on Saturday that lever travel had increased significantly since the start of the ride, having a look at the bike a minute ago the lever can now be pulled so the shifter paddle reaches the bars which doesn't seem ideal.

    Brakes are Force AXS HRD. Is this likely to be pad wear increasing piston travel or pressure loss in the system? Pads on the front do look fairly worn so can replace these. Is this likely to fix the problem or do I need to purchase a bleed kit? Should I be adjusting contact point throughout the wear of the pads?

  • You wouldn’t be the first to wear down a set of pads after a ride in the wet UK grit.

    Three usual issues would be:

    1) air in the line (needing a brake bleed), 2) the pads need adjusting, or
    3) the pads need replacing.

    For 1)...
    Stand your bike horizontal-ish and pump the lever(s) 6-12 times. If the lever action doesn’t improve see other replies in the previous couple of pages for adjusting pads. If the levers did get firmer, leave the bike horizontal for an hour, then pull the lever once. If the lever action went mushy again, then you need a bleed. If it stayed firm, leave for a day and repeat. If it then goes mushy, you need a bleed. If it stays firm, then sounds like it’s fixed and you’re welcome.
