bubbles are seen on the 4
th
or 5
th
attempt. If bubbles are seen repeat until
no bubbles appear.
4. Minimize the caliper volume.
Using channel locking pliers, or
similar, squeeze the caliper as
shown to push the piston back
as far as possible into the
caliper. While squeezing, open
and close the caliper bleeder
looking for bubbles. Repeat at
least three times looking for
bubbles. If bubbles are seen
repeat until not bubbles
appear.
5. Overfill the master cylinder to minimize the amount of air in the reservoir
before reinstalling the cap. Yes, you will loose some fluid when the cap
goes on. Have the rubber in the cap pushed up to minimize its volume.
Front Brakes
Bleeding of the front brakes is
similar but step 4 requires the use
of a screwdriver to force the pads
& pistons back into the caliper.
Proper adjustment requires the
following steps.
1. Remove the protective rubber
boot that covers the system.
2. Adjust the lever to the desired
‘home’ position by using the
Position Adjustment Screw.
3. Ensure that there is freeplay at the location shown in the picture below, by
adjusting the Freeplay Adjustment Knob.
NOTE:
There is a small set screw (2mm allen) on the lever, toward the grip, that allows the
Freeplay Adjustment Knob to be locked into position.
4. At this point, if the brakes do not have a solid enough feel try; 1) bleeding the
brake system, and 2) replacing older brake pads with new ones.
NOTE:
If a more solid brake feel is desired, it may be possible to tighten up the
adjustment by eliminating the freeplay with the Freeplay Adjustment Knob but
this should only be done in conjunction with removing the master cylinder
reservoir cap to ensure that the fluid returns to the master cylinder.
