These bolts should not be removed for any
reason! If you have the proper tool, you can
check that the torque is 50-55 In. Lbs.
Otherwise, don’t touch them!
About the Spreader Clip:
Avid’s TYPE N Ball Bearing Disc Brakes utilize a pad spreader clip that sits between the pads (instead of magnets) to
keep them retracted. The original spreader clip had two ears with loops that protruded from the caliper, but we have
since changed the design. The new clip works exactly the same way, but has nothing sticking out of the caliper.
