Hydraulic brakes that use DOT fluid, such as Formula, Avid and Hayes should be flushed and re-bled periodically.
DOT fluid is hydrophilic, meaning it absorbs water. Atmospheric moisture gets through the seals and around the pistons of the brake which causes performance to degrade. This can actually produce bubbles in the system as the moisture boils under hard braking.
Bottom line: For best performance of DOT systems, consider changing the fluid and replacing the pads at the same time.
Suspension Pivots and Linkages
Suspension pivots, linkages, and shock bushings that are not maintained can cause extra wear on the bearings and mounting points. Often, unmaintained pivot hardware will seize to the bearings, causing creaking. Commonly, unmaintained bearings will develop play. This can cause them to literally fall apart as the balls corrode and lose surface area.
Bottom line: Suspension pivots and linkages should be disassembled, cleaned, have bearings inspected, greased or treated with loctite, then re-assembled to torque spec once a year. Or more often with wet riding.
