"When installing parts in a disc brake you have to make sure to use the proper
lubricant, a lubricant that will not affect the seals. The fluid used in the
system whether it is DOT or Mineral oil is a great lubricant."
great article, the only exception I have is the above information. DOT or
Mineral Oil are not lubricants but brake fluids
the correct seal lubricant (whether a seal in the MC or Caliper) is high-
temperature silicon grease
using DOT fluid to 'lubricate' the piston seals feels fine when rebuilding but
does nothing in the long term to address piston drag, which was a notorious
problem for older Hayes disc brakes with their ceramic pistons
the silicon grease is the correct lubricant and ensures great long term
performance with minimal piston issues going forward; just make sure to
degrease each caliper half (after pushing the pistons home) with ISO Alchohol
after using silicon grease as you don't want any excess getting onto the brake
pads or rotor..
